General Information  
2.1  
Technology  
PROTECT 1. is an Uninterruptible Power  
Supply (UPS) for essential loads such as small  
data centres, servers, network components,  
telecommunications equipment and similar  
units. It consists of:  
i
Mains filter with overvoltage protection (appliance  
protection / class D) and mains energy backfeed  
protection  
Rectifier section with PFC logic  
(power factor correction unit)  
Separate battery charger with  
switch mode power supply technology  
IGBT inverter for continuous supply of connected loads  
with sinusoidal AC voltage  
Automatic electronic bypass (SBS)  
as additional, passive redundancy  
SBS = Static Bypass Switch  
Manual bypass for maintenance and  
service purposes (with automatic  
SBS activation upon actuation)  
Control unit  
on the basis of digital signal processor technology  
7
 
2.2  
System Description  
The UPS is connected between the public utility mains and  
the loads to be protected.  
The power section of the rectifier converts the mains voltage to  
DC voltage for supplying the inverter. The circuit technology  
used (PFC) enables sinusoidal current consumption and  
therefore operation with little system disturbance. A separate,  
second rectifier (charging REC set up using switch mode power  
supply technology) is responsible for charging or trickle-charging  
the battery connected in the intermediate circuit. The  
configuration of this charging REC means the harmonic content  
of the charging current for the battery is almost zero, which  
increases the service life of the battery even more. The inverter  
is responsible for converting the DC voltage into a sinusoidal  
output voltage. A microprocessor-driven control based on a  
pulse-width modulation (PWM) guarantees, in conjunction with  
digital signal processor technology and extremely fast pulsating  
8
 
IGBT power semiconductors of the inverter, a voltage system of  
the highest quality and availability on the secured busbar.  
In the event of mains faults (such as e.g. current failures), the  
voltage continues to be supplied from the inverter to the load  
without any interruption. From this point onwards, the inverter  
draws its power from the battery instead of the rectifier. Since no  
switching operations are necessary, there is no interruption in  
the supply to the load.  
The automatic electronic bypass serves to increase the reliability  
of the supply further, especially in the case of individual systems.  
It switches the public mains directly through to the load without  
any interruption, e.g. when there is an inverter malfunction. As a  
result, the automatic bypass represents an extra passive  
redundancy for the load.  
An integrated, manually operated bypass unit ensures an  
uninterrupted supply to the connected loads in the case of  
maintenance and/or service work. The internal electronic part  
(with the exception of the metal-clad manual bypass) can be  
disconnected via the mains input miniature circuit breakers.  
The greatest possible supply reliability of connected loads is  
attained by the parallel connection of up to max. three  
PROTECT 1. UPS systems. The n+x technology thus  
guarantees maximum reliability through up to double active  
redundancy on the one hand as well as on the other hand the  
possibility of increased power with simple redundancy or even  
only higher UPS power without any redundancy. The relationship  
between the available output power and the degree of active  
redundancy can be seen in the following overview:

and operating conditions of the PROTECT 1.,  
capable of recognising and preventing dangers.  
Regulations and definitions for qualified personnel can be  
found in DIN 57105/VDE 0105 Part 1.  
3.4  
Safety Instructions for PROTECT 1.  
The UPS is live, and the voltage can be  
dangerous. The unit may only be installed and  
if necessary opened by trained and qualified  
personnel. Repairs may only be carried out by  
qualified customer service staff!  
The output can be live, even when the UPS is not  
connected to the mains supply!  
16  
 
For health and safety reasons, the unit must be  
earthed correctly!  
The PROTECT 1. may only be operated with or connected to  
a three-phase power system with protective grounding using  
a mains connection cable with PE conductor that has been  
tested according to German standards (VDE).  
Risk of burning!  
The battery has powerful short-circuit currents.  
Incorrect connection or isolation faults can lead to  
melting of the plug connections, sparking potential  
and severe burns!  
The unit has a warning signal that sounds when  
the battery voltage of PROTECT 1. is exhausted  
or when the UPS is not working in its normal  
mode (see also chapter 8 "Signalling”, page 47  
and the following).  
Observe the following safety instructions to  
ensure permanent operational safety of and safe  
work with the UPS and the battery modules  
(special accessories):  
Do not dismantle the UPS!  
(The UPS does not contain any parts that require  
regular maintenance. Bear in mind that the warranty  
will be invalidated if the unit is opened!)  
Do not install the unit in direct sunshine or in close  
proximity of heaters!  
The unit is designed to be installed inside in heated  
rooms. Never install the housing in the vicinity of water  
or in an excessively damp environment!  
Condensation may occur if the UPS is brought from a  
cold environment into the room where it is to be  
installed. The UPS must be absolutely dry prior to start-  
up. As a result, leave it to acclimate for at least two  
hours.  
Never connect the mains input and the UPS output!  
17  
 
Ensure that no fluids or foreign bodies can penetrate  
the housing!  
Do not block the air vents of the unit! Make sure, for  
example, that children do not insert any objects in the  
ventilation openings!  
Do not connect household appliances such as  
hairdryers to the UPS! Also take care when working  
with motor loads. It is essential to avoid back-feeding  
the inverter, e.g. if the load is intermittently operated in  
regenerative mode.  
Danger! Electric shocks!  
Even after the mains voltage has been  
disconnected, the components within the UPS  
remain connected to the battery and can thus  
cause electric shocks. It is therefore imperative  
to disconnect the battery circuit before carrying  
out any maintenance or repair work!  
If it is necessary to replace the battery or carry  
out maintenance work, this must be done by or  
under the supervision of a specialist familiar  
with batteries and the necessary safety  
precautions!  
Only authorized persons are allowed in the  
vicinity of the batteries!  
When replacing the batteries, the following must be observed:  
Only ever use identical, maintenance-free sealed lead  
batteries with the same data as the original batteries.  
Danger! Explosive!  
Never throw batteries into open fire.  
Never open or damage batteries. (Electrolyte  
may leak out and damage skin and eyes. It may  
be toxic!)  
Batteries can cause electric shocks and high  
short-circuit currents.  
18  
 
Therefore, take the following safety precautions when working  
with batteries:  
Take off watches, rings and other metallic objects!  
Only use tools with insulated handles!  
Avoid using multiple outlet adapters with a  
central on/off switch as protection against  
uncontrolled load switch-off as well as for  
avoiding peak inrush currents.  
i
Switch OFF the UPS using its main switch if you do not intend  
to use it for some time. PROTECT 1. must be switched off  
every evening if the electricity supply in your company is  
switched off every night. Otherwise, the battery will be  
discharged. Frequent and exhaustive discharging of the  
battery leads to a shorter service life of the battery and should  
therefore be avoided!  
For personal safety reasons, never switch on  
the main switch when the mains connector of  
PROTECT 1. is disconnected!

the weight. It may be necessary to engage the help of a  
second person.  
4.2  
Transport to Installation Site  
The PROTECT 1. is equipped with transport rolls for easy  
transport to the intended installation site. It is recommended  
to install the UPS where:  
The connection work can be conveniently carried out;  
There is enough space for proper operation and, if  
necessary, for periodic and extraordinary maintenance  
work; in this regard, the connection cables should be  
long enough to move the UPS (to open the UPS if  
necessary) without having to switch it off.  
The use of an external manual bypass is recommended  
The UPS is protected against external atmospheric  
influences;  
The humidity and the ambient temperature are within  
the limits;  
The fire protection standards are observed.  
The battery service life strongly depends on the ambient  
temperature. Ambient temperatures between+15° and +25°C  
are optimum.  
Attention!  
Only transport the PROTECT 1. in an upright  
position! Never tilt or cant it; avoid displacing  
the centre of gravity!  
Make sure that no magnetic storage media are stored and/or  
operated close to PROTECT 1.  
22  
 
4.3  
Set-Up  
Note the following points when setting up the UPS system  
and its external battery units (special accessories):  
The contact surface must be smooth and level. It must  
also be sufficiently strong and sturdy to avoid vibration  
and shocks.  
Make sure that the mounting is able to support the  
weight, especially in conjunction with external battery  
units (special accessories).  
Set up the units so that adequate air circulation is  
assured. There must be at least 200 mm clearance  
behind the rear fans for ventilation purposes. Do not  
block the intake openings on the front and, if present,  
on the side of the unit. There must be a gap of at least  
50 mm here.  
External battery units must be placed on the side of the  
UPS system. To ensure the greatest possible  
mechanical stability, do not place the external battery  
unit(s) above or below the UPS system.  
Avoid extreme temperatures! We recommend an  
ambient temperature from 15°C to 25°C in order to  
maximize the service life of the batteries. Do not  
expose the units to direct sunlight or operate them  
close to other heat sources such as radiators.  
Protect the units against external effects (in particular  
moisture and dust). In this regard, please also refer to  
the instructions in chapter 3, page 15 in these operating  
instructions.  
If you transport the unit from a cold room into a warm one, or  
if the room temperature suddenly drops, then condensation  
may form inside the unit. To avoid any damage due to  
condensation, let the unit acclimate for 2 hours before you  
switch it on.

Electrical Connection  
Caution  
Prior to commencing work, ensure that the  
connection cables are de-energised and that it  
is not possible to activate the power supply.  
In order to avoid deformation of the supporting  
rail and to protect the base of the connection  
terminal against torsional forces, it is advisable  
to hold the cable in position when tightening the  
clamping screw.  
i
The protective measure of earth connection serves to prevent  
excessive touch voltage on freely accessible metal parts. The  
PROTECT 1. is earthed by the provided earthing bolts (  
/
PE). Prior to start-up, it must be ensured that the PROTECT 1. is  
earthed in accordance with valid regulations, e.g. VDE 0100.  
Before the connection work is carried out, check that:  
The values of the nominal voltage (input voltage) and  
frequency match those on the nameplate of the UPS.  
The earth connection matches the prescribed IEC  
standards or the local regulations,  
The UPS is connected to the electrical mains via a  
separate supply line equipped with fuses on the supply-  
side MI distribution.  
The power fuse in the MI distribution has the same or  
higher value as the one indicated on the nameplate of  
the UPS system.  
28  
 
5.1  
Safety of Personnel  
Note the following points when setting up the UPS system  
and its external battery units (special accessories):  
Disconnect the unit from the power supply  
Secure the unit against being switched back on  
Verify that the unit is disconnected from the power  
supply  
Earth and short-circuit the unit  
Provide protection by covers or barriers for any  
neighbouring live parts  
5.2  
5.3  
Mains Connection (General)  
In order to ensure the correct functioning of the UPS and its  
additional equipment, it is necessary to equip the mains cable  
with the corresponding fuses.  
Checklist for Cable Connections  
The connection and earthing terminals of all PROTECT 1.  
units are structured in a similar way. The cables are  
connected as follows:  
Remove terminal cover (retain the four screws).  
Insert the cables to be connected into the terminal  
space of the PROTECT 1. from the rear.  
Connect the wires of the supply lines to the  
corresponding terminal block. Connect the PE to the  
terminal block of the PROTECT 1.100 or to the strain  
relief unit of the PROTECT 1.150 or 1.200.  
Fasten the supplied cable clamping unit (no. 9, p. 26/27)  
with the previously removed screws.  
In the case of the PROTECT 1.150 and 1.200, also  
remove the lateral earthing bolts beforehand and use them  
to fasten the cable clamping unit as well.  
Check to ensure that the cables are secured correctly  
and tighten the fixing bolts if necessary.  
Remove any cable debris, tools, bolts, etc. from the  
connection panel.  
29  
 
Mechanically secure the cables with the strain relief  
clamps of the cable clamping unit.  
Mount the connection cover of the cable clamping unit.

Mains Connection  
5.4.1  
Preparation for the three-phase mains connection  
Before connection work is performed on the UPS, make sure  
that:  
The values of the nominal voltage (supply) and  
frequency match those on the nameplate of the UPS.  
The earth connection matches the prescribed IEC  
standards or the local regulations,  
The UPS can be connected to the electrical mains via a  
separate supply line equipped with fuses in the supply-  
side MI distribution.  
Back-up fuses or line safety switches are used that  
correspond to the values listed in chapter 5.2.2.  
The connection cable from the back-up fuse to the UPS  
is configured with a minimum cross-section acc. to  
chapter 5.2.2 “Connection Cross-Sections and Fuse  
Protection”.  
The UPS can be live, and the voltage can be  
dangerous. The unit may only be installed and  
if necessary opened by trained and qualified  
personnel. Repairs may only be carried out by  
qualified customer service staff!  
5.4.2  
Connection of the Three-Phase Input Mains Voltage  
In order to ensure the safety of personnel during installation  
work, make sure that the connections are made under the  
following conditions:  
No mains voltage present.  
The loads are switched off.  
The PROTECT 1. is switched off (display completely  
blank).  
To disconnect the PROTECT 1, carry out the following steps  
as well:  
31  
 
Place the “maintenance switch” manual bypass on the  
back of the UPS in the “bypass” position. To do this, first  
remove the 4 screws of the cover (no.3, p. 26/27).  
Put the mains input miniature circuit breaker (no.2,  
p. 26/27) in the “OFF” position.  
Connect the UPS terminal “  
/ PE“  
(earth)  
with  
the  
corresponding earth terminal in the distribution cabinet.  
Connect the supply cable from the MI distribution to the  
terminals 1.1 of the UPS that are marked with “INPUT”:  
/ PE

Ground  
N
Neutral conductor  
Phases  
L1/L2/L3 =  
Check the jumper between “JP1” and “JP2”  
(terminal designation “JUMPER”).  
Only remove the cable if you want to use the UPS  
in parallel operation with further PROTECT 1. units  
of the same type (see also chapter 9).  
5.4.3  
Preparation of the Output Cabling  
Before you connect the loads to the UPS, the nominal output  
listed on the nameplate must be greater than or equal to the  
sum of the load power outputs.  
The output of the PROTECT 1. should supply further separate  
circuits in a subdistribution. Make sure that the fuse protection is  
selectively designed (see also chapter 5.2.2).  
For the connection between the PROTECT 1. and the  
subdistribution, cable cross-sections acc. to the table  
“Connection Cross-Sections and Fuse Protection” on p. 30  
must be used. In the subdistribution, note at least the  
following information:  
Maximum permissible total load  
Maximum permissible load of the individual load circuits  
In the case of a common distribution cabinet  
(circuits with mains as well as UPS voltage), label  
each circuit with the respective supply (mains or  
UPS).

5.4.4  
Connection of the Loads  
In order to ensure the safety of personnel during installation  
work, make sure that the connections are made under the  
following conditions:  
No mains voltage present.  
The loads are switched off.  
UPS is switched off (display completely blank).  
To disconnect the PROTECT 1., carry out the following steps:  
Place the “maintenance switch” manual bypass on  
the back of the UPS in the “bypass” position. For  
this purpose, first remove the 4 screws of the  
cover (no. 3, p. 26/27).  
Put the mains input miniature circuit breaker (no.2, p.  
26/27) to the “OFF” position.  
Connect the loads as follows (terminals 1.3, p. 26/27):  
Connect the UPS terminals  
/PE = ground, N = neutral  
conductor, L = phase that are marked with “OUTPUT” with the  
corresponding terminals of your UPS subdistribution.  
5.5  
Connection of External Battery Modules  
The PROTECT 1. requires the use of at least one external  
battery module. Two preconfigured battery cubicle types are  
available. Both versions guarantee an increase in the  
attainable standby time due to their parallel connection  
capability (see also chapter 2.3).

using the PROTECT 1.BP20.  
33  
 
5.5.1  
Connection of the Battery Cubicle PROTECT 1.100 BP  
This battery cubicle is completely preconfigured. The  
connection to the UPS unit is ready to be plugged in as a  
result of the supplied battery connection cable.  
PROTECT 1.100 with 1 battery unit PROTECT 1.100 BP  
PROTECT 1.100 BP is only intended  
for connection to the UPS type PROTECT 1.100.  
i
Connect further battery cubicles of identical design (!) to the  
second battery connection socket of the neighbouring battery  
cubicle. Insert the battery connection plugs quickly and firmly  
into the battery connectors.  
34  
 
5.5.2  
Connection of the Battery Cubicle PROTECT 1. BP20  
Fig.: Rear view of the PROTECT 1.BP20 with cover removed.  
The battery cubicle is supplied with a separate battery string  
and separately enclosed battery fuses for safety and transport  
protection reasons. Please also note the separate  
documentation enclosed with the battery cubicle.  
After the battery cubicle has been removed from the pallet,  
first remove the rear cover. Now create the electrical  
connections with the enclosed connectors (see also circuit  
diagram X1/X2/X3) and ꢁ  
The PROTECT 1.100 is connected to the UPS at the socket  
using the special battery connection cable enclosed with  
the UPS, and in the case of the PROTECT 1.150 or  
PROTECT 1.200 with the battery connection cables enclosed  
with the battery cubicle at the terminals. Make sure to observe  
the terminal block assignment concerning the correct polarity  
"+" and "-" as well as an earth-fault- and short-circuit-proof  
routing, in addition to the proper earthing of the battery  
cubicle.  
35  
 
If the battery cubicle is used in connection with the  
PROTECT 1.1.50 or PROTECT 1.200, the strain relief is  
implemented with clamps.  
The battery system can now be activated. To do this, insert  
the two fuses .  
As the last step, fasten each cover that was initially removed.  
Fig.: PROTECT 1.BP20 in connection with the PROTECT 1.100  
PROTECT 1.100 & 1.BP20: When connecting  
the battery connection cable, make sure that the

battery connectors.  
i
Prepare further PROTECT 1.BP20 battery cubicles as  
described above and then connect them to the terminals ꢁ  
(X2 and X3) of the previously installed battery cubicle with the  
enclosed battery connection cables. Observe the correct  
polarity "+" and "-" as well as an earth-fault- and short-circuit-  
proof routing during connection.  
5.6  
Mechanical Blocking of PROTECT 1.  
After completing the connection work, fasten the connection  
terminal cover again. At the final installation site, block the  
cubicles against slipping.  
36

Start-Up  
Compare the setting of the nominal output voltage of the UPS  
with the rated voltage valid in your country. The factory  
presetting is 230 V. Changes to 220 VAC or 240 VAC can be  
made with the software “CompuWatch”.  
Switching on the PROTECT 1. on the mains  
1.  
Make sure that all connections have been made  
according to the installation instructions.  
2.  
3.  
Make sure that all loads are switched off.  
Put the “maintenance switch” manual bypass  
switch (no. 3, p. 26/27) on the back of the UPS  
back to the “USVposition. Next fasten the cover  
again with the 4 previously removed screws.  
4.  
5.  
Now insert the back-up fuse in your low-voltage main  
distribution (where the UPS system is connected to  
the mains on the input side) or switch on the  
corresponding line protection switch there.  
Next actuate the mains input miniature circuit  
breakers on the UPS (no. 2, p. 26/27). Move this  
to the "ON" position.  
Factory presetting: The loads are supplied via  
the integrated bypass, which connects the  
phase L1 with the UPS output. Do not switch on  
your loads yet, however.  
i
6.  
7.  
Now switch on the inverter of the UPS. To do this,  
press the ON pushbutton for approx. 2 seconds.  
After switching on, the UPS carries out a self-test,  
during which the LED’s for load and battery state  
go on and off consecutively in increasing order.  
After the successful synchronization of the  
inverter, the Inverter LED lights up a few seconds  
later, whereby the UPS is now in normal  
operating mode. When the mains supply is intact  
(mains within tolerance), the "Line" LED also  
lights up.  
37  
 
Please shut down the entire system again if you  
cannot solve a problem that occurs. To do this,  
press the OFF pushbutton for approx. 2 seconds.  
Disconnect the UPS from the mains by actuating  
the mains input miniature circuit breaker (no. 2,  
p. 26/27). Please contact our hotline (see p. 4).  
i
8.  
When the displays are correctly lit as described,  
switch on your loads one after the other. When  
doing this, take care not to exceed the maximum  
permitted load capacity of the UPS.

Once you have connected the UPS to a suitable mains  
connection, you can start operation using the UPS main  
switch. Normally, the UPS operates continuously. The UPS  
now supplies the output with voltage, which is signalled by the  
mains symbol (Line LED) and the inverter symbol (Inverter  
LED) being lit.  
This operating mode, generally referred to as “online” mode,  
ensures the greatest protection, in particular when there are  
mains fluctuations and mains failures, because the loads are  
38  
 
continuously supplied with reliable and “clean” voltage with no  
interruptions in this operating mode.  
The bar graph LED (LED chain above the pictograph)  
indicates the current capacity utilisation of the UPS in this  
operating mode (see chapter 8, p. 45).

The mains is not within the required tolerance range or has  
failed. In this case, power is supplied to the inverter from the  
charged battery without interruption. The power supply to the  
loads is therefore also ensured in the event of a mains failure.  
This drains the capacity of the battery and it is discharged.  
This status is signalled by the battery symbol lighting up  
(Battery LED), as well as an intermittent acoustic signal, at  
first every 4 seconds and then every second shortly before  
switching off. The initial alarm can be suppressed by pressing  
the “Alarm off” button. The alarm is automatically reactivated  
when the battery capacity decreases. Depending on the  
expansion level, age and condition of the battery and in  
particular on the load to be supplied, the standby time can  
vary from a few minutes to several hours.  
39  
 
The inverter is switched off if the battery voltage drops below  
a factory-set minimum voltage value.  
Never store the unit in this condition! The discharged battery  
system should be recharged within a week at the latest.  
When the voltage and frequency are within the tolerance  
range again after the mains is restored, the rectifiers switch  
back on automatically. The supply of the inverter through the  
mains is resumed and the battery charger charges the  
battery.  
The bar graph LED (LED chain above the pictograph)  
indicates the remaining battery capacity during this operating  
mode (see chapter 8, p. 45).

Load  
If the inverter is overloaded or if overtemperature is detected,  
e.g. also if an inverter defect is detected, voltage is supplied  
to the load without interruption via the static bypass switch  
(SBS) that switches on automatically. This is signalled by the  
Bypass LED.  
40  
 
This so-called passive redundancy protects against the total  
failure of the voltage supply on the secured busbar; however,  
in this operating mode, mains faults would directly affect the  
load. As a result, the electronics continuously attempt to  
switch back to "online" / normal operating mode (e.g. when  
the overload or overtemperature goes away).  
The bypass consists of an inverse-parallel thyristor stack and  
functions as an extremely rapidly switching link between a  
load and the mains. The synchronization unit ensures that the  
frequency and phase of the inverter voltage is synchronized  
with the mains and can therefore be switched over without  
interruption (within the tolerance limits).  
The bar graph LED functions as the display of  
the UPS capacity utilisation. The acoustic signal  
sounds every 2 seconds during this operating  
mode.  
i
6.1.4  
Manual Bypass  
41  
 
The manual bypass enables maintenance and service  
personnel to perform work on the PROTECT 1. without  
having to switch off the load circuit.  
If the current supply fails while the manual  
bypass is active, a total failure of the load supply  
results. For this reason, it should be switched  
back to normal operating mode as soon as  
possible.  
6.1.5  
Unit overload  
The load on the UPS should never exceed the specified rated  
load of the unit. If a unit overload occurs nevertheless (from  
105% of the specified unit rated load) then the Fault LED lights  
up and an acoustic signal sounds (twice per second). The  
connected loads continue to be supplied for a certain length of  
time depending on the level of the overload. However, the  
connected load must be reduced without delay.  
Non-observance of the "unit overload" condition may cause  
the total loss of all UPS functions!  
Also avoid short-term unit overloads, which may, for example,  
occur when connecting a laser printer or laser fax machine.  
Do not connect any household appliances or machine tools to  
the UPS.  
Never connect or switch on any additional loads  
to the UPS if there is a mains failure, i.e. if the  
UPS is working in emergency power mode!  
As a rule, if there has never been an overload during normal  
mode, there will not be one in battery mode either.  
When the Fault LED lights up in connection with  
a continuous acoustic signal, this is an indication  
of a deactivating fault. Follow the instructions on  
page 49.

Interfaces and Communication  
7.1  
Computer Interface RS232  
For the control of the UPS and convenient reading of status  
messages and measured values, various interfaces are  
available. The interface protocol is designed for operation with  
the "CompuWatch" shutdown and UPS management software  
from AEG. Use the supplied RS232 communication cable to  
connect your PC. Plug the cable into a corresponding serial  
port on your PC.  
RS232 interface: The RS232 is connected via the 9-pin Sub-D  
socket strip on the back of the unit (no. 8, p. 26/27). Pin  
assignment: 2 = TxD; 3 = RxD; 5 = GND.  
7.2  
Communication Slot  
On the back of the UPS, there is a cover (see p. 26/2727, no.  
7). When this is removed, additional, optionally available  
communication components can be installed there, e.g.:  
AS/400 board: Slot board with status messages, realised via  
potential-free relay contacts  
USB board: Slot board for communication via USB  
SNMP board: Slot board for direct connection of the UPS to  
the Ethernet network with RJ 45 (TCP/IP)  
Details can be found in the description enclosed with the  
particular optional component. Other boards in preparation.  
Using the communication slot deactivates the  
RS232 interface from chapter 7.1.  
i
7.3  
Shutdown and UPS Management Software  
The "CompuWatch" software specially developed for these  
purposes by AEG continuously checks the mains supply and  
the UPS status.  
In conjunction with the “intelligent” UPS, this guarantees the  
availability of the EDP components as well as the data  
security.  
43  
 
The "CompuWatch" shutdown software supports different  
operating systems, e.g. Windows 98SE/ME, Windows  
NT/2000/XP, Windows Vista, Linux, Novell Netware, IBM AIX,  
HP-UX, SUN Solaris, Mac OS X, and others.

Parallel Operation  
9.1  
Principle of Operation  
PROTECT 1. has been designed for parallel operation with n+x  
technology (“n” here stands for the number of units required for  
load supply, “x” for the degree of redundancy). Up to 3 units of the  
same type can be connected in parallel here to increase the  
output power and/or achieve higher availability.

51  
 
The actively redundant parallel operation automatically  
switches to power-increasing operation if the output power  
requirement exceeds the UPS single block power, i.e. the  
degree of redundancy is decreased or is completely eliminated.  
Conversely, the active UPS redundancy degree automatically  
increases again when the power consumption decreases.  
The connection normally takes place in the low-voltage main  
distribution, which also contains the external manual bypass  
and the following subdistribution of connected load circuits.  
Such a parallel board can be purchased in a wall housing incl.  
external HU as well as feeder and load distribution board from  
AEG Power Solutions via your specialist dealer.  
9.2  
Set-up / Connection of Parallel Operation Board  
The mains connection of each individual UPS takes place in  
the same way as described in chapter 5.  
The three-phase mains connection secured for  
each UPS must always have the same phase  
sequence, i.e. all UPS units are supplied at the  
input terminals L1, L2 and L3 by the same  
phase each time (no mix!).  
In UPS bypass mode, the phase L1 is used to  
connect the single-phase load with the mains.  
The central external manual bypass, which must  
have an all-pole design, must also be supplied  
by this phase L1.  
The UPS outputs are each connected with the parallel  
operation busbar via an isolator. The instructions from  
chapter 5 apply here too.  
The following always holds true for the UPS input and output  
conductors: The difference in length in conductors up to 20 m  
per UPS can be max. 20% and max. 10% for lengths > 20 m  
per UPS.  
The jumper installed between “JP1” and “JP2” on the  
connection panel of every UPS at the factory must be  
removed. The UPS output distribution also has to take place  
according to the instructions in chapter 5. In particular, make  
sure that the individual switching elements are correctly  
labelled, in order to prevent operating errors later as well. The  
52  
 
communication of the units switched in parallel takes place  
via the 25-pin parallel operation cable(s) included in the scope  
of delivery.  
For this purpose, first remove the parallel port covers  
(no. 5, p. 26/27) and connect the UPS units with each other  
with one parallel operation cable each. Use one parallel  
operation cable for 2 units and two parallel operation cables for  
3 units (do not create a ring structure!).  
(Communicative) parallel operating connection  
... for 2 units:  
... for 3 units:  
After connecting the parallel operation cables, fasten the  
previously removed parallel port covers. Turn these by 180°  
so that the slot of the cover is facing downwards.  
The hardware-related installation is now complete.  
9.3  
Operation of the UPS in a parallel system  
The start-up process is uncomplicated, does not require any  
prior knowledge and is basically oriented to the procedure  
described in chapter 6. If you have obtained the parallel  
operation board from AEG Power Solutions, you can find  
further special instructions there. The displays in the parallel  
system function the same way as described for the individual  
UPS units in chapter 8.  
9.3.1  
Start-Up  
1.  
Make sure that all connections have been made  
according to the installation instructions.  
2.  
3.  
Make sure that all loads are switched off.  
Make sure that all “maintenance switch” manual  
bypass switches (no. 3, p. 26/27) on the back of  
53  
 
each UPS are in the “Bypass” position and all  
mains input miniature circuit breakers (no. 2, p.  
26/27) on the back of each UPS are in the “OFF”  
position.  
4.  
5.  
6.  
Check the position of the central external manual  
bypass. This must be in the “Bypass” position, i.e.  
supply of the load busbar by the supplying mains.  
Now close all isolators in the output of each UPS,  
i.e. connect the output of each UPS with the  
parallel operation busbar.  
Now insert the back-up fuses in your low-voltage  
main distribution (where the central external manual  
bypass as well as the individual UPS systems are  
connected to the mains on the input side) or switch  
on the corresponding line protection switches there.  
The load supply now takes place via the central  
external manual bypass, and the parallel  
operation busbar is supplied with power via the  
integrated manual bypasses of each UPS.  
However, the parallel operation busbar and load  
busbar are not yet connected to each other at  
this time!  
i
54  
 
7.  
8.  
Now actuate the mains input miniature circuit breakers  
(no. 2, p. 26/27) on each UPS one after the other.  
Move them to the "ON" position.  
Move the “maintenance switch” manual bypass  
switches (no. 3, p. 26/27) on the back of each  
UPS to the “UPS” position. Finally, fasten the  
covers on each UPS again using the 4 respective  
screws that were previously removed.  
The voltage supply of the parallel operation  
busbar now takes place via the integrated  
electronic bypass switches of the UPS systems  
used. Check this operating state on the display  
panel of each UPS = Bypass (chapter 6.1.3).  
i
9.  
Now actuate your central external manual bypass:  
Switch from the “Bypass” position to “UPS operation”,  
i.e. connect your load busbar to the UPS parallel  
operation busbar.  
This is done using a manual bypass switch with  
overlapping switching contacts without any  
interruption in the load voltage, i.e. completely  
interruption-free.  
i
10.  
Now switch on the inverters of the UPS systems.  
To do this, press the ON pushbutton of each UPS  
for approx. 2 seconds one after the other.  
After switching on, each UPS carries out a self-  
test and synchronizes itself with the parallel  
operation busbar, while the LED’s for load and  
battery state switch on and off consecutively in  
i
increasing  
order.  
After  
the  
successful  
synchronization of all inverters, the Inverter LED  
on each UPS lights up a few seconds later,  
whereby the UPS systems now work in parallel  
normal operating mode and supply the parallel  
operation / load busbar with UPS voltage.  
The central external manual bypass switch must  
be protected against accidental actuation. Never  
actuate it when the UPS systems are in inverter  
mode.  
55  
 
11.  
When the displays are lit as described, switch on  
your loads one after the other. When doing this,  
take care not to exceed the maximum permitted  
load capacity of the UPS systems. Also take into  
account the reserve capacities if active  
redundancy should be required.  
9.3.2  
Changes to the parallel system  
If you would like to add a UPS to the parallel system or  
remove a UPS from the parallel system, this step is always  
done by returning the UPS systems to BYPASS operating  
mode.  
Load supply through mains operation!  
(No UPS protection during this measure).  
i
First, switch off the inverters of the UPS systems one after the  
other (actuate the “OFF” pushbuttons). All UPS systems  
function in SBS/bypass operation. Check the operating state  
on the operating panels. Next, active the integrated manual  
bypasses (no. 3, p. 26/27) on the back of each UPS. To do  
this, first remove the 4 screws of the covers on the back.  
Put the mains input miniature circuit breakers of each UPS  
(no. 2, p. 26/27) to “OFF” position. Use your central external  
manual bypass to bypass the loads, i.e. activate the bypass  
operation and remove the load supply from the UPS busbar.  
The voltage of each UPS is disconnected in its low-voltage  
main distribution. You can now expand or reduce your parallel  
system. Pay attention to the jumpers “JP1” / “JP2” and the  
parallel operation cables. The subsequent start-up is carried  
out as described in chapter 9.3.1.  
If you only want to switch off a UPS in the  
parallel system, press the “OFF” pushbutton  
twice in succession to do this. In this way,  
individual UPS systems can be disconnected  
from the parallel operation busbar.

Maintenance  
The PROTECT 1. consists of state-of-the-art, non-wearing  
components. We do, however, recommend visual checks  
(above all battery and fan checks) at regular intervals (at least  
every 6 months) to maintain continuous availability and  
operational reliability.  
CAUTION!  
Ensure that the work area is cordoned off and  
always observe the safety instructions!  
10.1  
10.2  
Charging the Battery  
The battery is automatically charged when the mains is  
connected, irrespective of the operating mode. This is  
signalled by the Load LED’s lighting up (see also chapter  
4.4.2).  
The complete charging time of the battery after a long  
discharge time depends especially on the number of  
additional external battery units (see chapter 2.3).  
Checks  
The following maintenance work should be performed:  
Task  
Interval  
Described in  
Chapter 10.2.1  
Chapter 0 / 0  
Visual check  
Battery/fan check  
6 months  
6 months  
10.2.1 Visual Check  
When visually inspecting the unit, check whether …  
there is any mechanical damage or foreign bodies can  
be found in the system,  
any conductive dirt or dust has accumulated in the unit,  
accumulation of dust affects heat supply and  
dissipation.  
57  
 
CAUTION!  
PROTECT 1. must be disconnected from the  
power supply prior to carrying out the following  
work.  
If large quantities of dust have accumulated, the unit should,  
as a precaution, be cleaned with dry compressed air, in order  
to ensure adequate heat dissipation.  
The intervals at which visual checks should be performed are  
largely determined by the site conditions.  
10.2.2 Checking the Battery  
Progressive ageing of the battery system can be detected by  
regular capacity checks. Every months, perform  
6
measurements to compare the achievable standby times, e.g.  
by simulating a mains failure. In this case, the load should  
always have approximately the same capacity demand.  
Please contact our hotline if the time drops drastically  
compared to the previous measurement (see p. 4).  
10.2.3 Fan Check  
Regularly check the fans for dust build-up and noticeably  
untypical noise development. Blocked intake openings must  
be cleaned. In the case of unusually loud or uneven running,  
please contact our hotline (see p. 4).  
58  
 
11  
Storage, Dismantling and Disposal  
11.1  
Storage  
Long storage times without charging or  
discharging the battery at regular intervals may  
lead to permanent damage of the battery.  
If the battery is stored at room temperature (20 C to 30 C), it  
will automatically discharge at a rate of 3-6% per month due  
to internal reactions. Storing the battery at temperatures  
above room temperature should be avoided. A high storage  
temperature also means greater battery self-discharge.  
Batteries that are stored at room temperature should be  
recharged every six months to maintain their full capacity and  
service life.  
Connect PROTECT 1. to the mains before  
putting it into storage, in order to make sure that  
the battery is fully charged. The charging time  
should at least match the time specified in  
chapter 10.1.  
i
11.2  
11.3  
Dismantling  
The system is dismantled in reverse order of the installation  
instructions.  
Disposal  
In the interest of environmental protection and recycling,  
please dispose of the individual system components in  
accordance with the regulations and legal guidelines when  
permanently taking the system out of operation. Please  
consider that infringements to these regulations may result in  
prosecution.
