1. Safety instructions and waste disposal rules
Warning!
Because several components of operating electrical devices are charged by dangerous voltage, the
improper handling of electrical devices may be the cause of accidents involving electrocution, injury,
or material damages.
•Operation and maintenance of electrical devices must be performed by qualified skilled
personnel such as electricians in accordance with EN 50110-1 or IEC 60950.
•Install the module only in areas with limited access to unskilled personnel.
•Before starting work, the electrical device must be disconnected from mains. Make sure that it
is earthed.
•Do not touch connector pins as they can be charged with dangerous voltage up to 30 seconds
after disconnection.
•Only spare parts approved by the manufacturer must be used.
All electric devices must be disposed of separate from domestic waste at collecting points that have
been set up by the government or municipal authority.
“Separate collection is the precondition to ensure specific treatment and recycling of WEEE and is
necessary to achieve the chosen level of protection of human health and the environment in the
Community.”
The above statement from EU directive 2002/96/EC applies to all electric devices installed within
EU countries.
In countries outside the EU, different rules may apply regarding waste disposal of electric devices.

2. General information
The PWS inverter family (1kVA–5kVA, 24V version max. 2.5kVA) is equipped with a 50Hz isolation trans-
former following a primary side pulse-width modulation stage and is available as 19”-compatible rack
(PWS-F) or wall mounted cabinet (PWS-W).
PWS inverters are especially suited for applications in power plants, industrial, railroad and shipping AC
power supplies. The combination of rugged mechanical construction, high overload ability and electrical
isolation between input and output offers a very high flexibility in system configuration.
The inverters can be operated as single unit or in parallel connection (as option) to provide power
increase or further improved reliability by (n+1)-redundancy. The operation in combination with a static
bypass switch (UNB) is also possible.
The PWS-F is fitted with a rear side connector, the PWS-W is fitted with screw terminals at the
bottom. All operation and indication elements are arranged at the front side.
The wall cabinet version includes all necessary input and output fuses and can be directly mounted
beside the load distribution. Optionally, versions with an included static bypass switch, special output
voltages, special output frequency or further special models are available on request.

2.6 Cooling and air flow direction
The PWS units are cooled with an internal fan. The airflow is from the front to rear side (PWS-F version),
from bottom to top (PWS wall cabinet version). The fan is monitored and speed-controlled dependent
on module temperature. To provide sufficient air flow, a minimum space (see figure 6a), item “A”) of 50
mm is required between the rear panel of the module and the rear cabinet wall as well as an unob-
structed supply of air to the front of the module. For PWS-W a minimum space of 2U (approx. 90mm)
above the top of the module (see figure 6b), item “A”) is recommended.

3. Handling
3.1 Storage
The modules must be stored in a dry, dust free environment with a storage temperature in accordance
with the technical specifications (see section 6).
3.2 Commissioning
Note: Before commissioning the module make sure that the input voltage level corresponds to the
nominal input voltage of the unit according to the type plate.
To mount the inverter in a 19’’ compatible cabinet, a mounting set is necessary (see figure 7).
After unpacking the unit put it upon the rails and slide in the unit carefully over the rails until the mod-
ule connector gets in touch with the backplane connector. Increase the pressure a little bit until the
unit fits in completely. Please avoid too much pressure. If the unit does not fit in please start again with
the complete slide-in process.
Mount the unit with 4 screws (M4x12).
Figure 7) - Mounting set for PWS-F (the picture shows not a PWS but a similar module)
For the connection of DC input and AC output the PWS-F is fitted with a backside panel connector (the
PWS-W is fitted with screw terminals at the bottom). The DC input is protected against incorrect
polarity (if the polarity is reversed, the unit does not switch on).
The PWS-W serially is equipped with an internal input and output fuse (see section 6.2 “Specific data”).
The PWS-F has no internal fuses. Therefore the module is to be fused with external fuses according to
section 6.2 “Specific data”.
Check the load current before connecting the module.
A permanent overload is not allowed and decreases the inverters lifetime. Especially the inrush cur-
rents of consumer loads have to be observed (e.g. the inrush current of a common used computer
monitor can be more than 50 A!).
For the safety of individuals, the connection of a non-fused protective earth conductor generally is
required. Due to the specific overload and short circuit behaviour of the PWS, additional safety meas-
ures are to be arranged at the output (e. g. ground fault circuit interrupter).

ELTEK VALERE INDUSTRIAL ©2008 UM_PWS_E_R1.2
Connect the input, output and signalling wires according to section 2.5 “Electrical connectors”. Wires in
accordance with VDE 0100 or equal standard are to be used. To decrease voltage losses on cables the
usage of larger wire cross sections as specified is recommended. For instance, a high voltage loss on
battery wires can decrease the backup time.
Following installation rules should be observed:
3.2.1 Single inverter
1. check the system wiring ( polarity of DC- supply line )
2. check that the inverter is switched off
3. connect DC input with open DC busbar fuses
4. connect AC loads
5. close the DC busbar fuses
6. switch on the unit with front side switch S1. The rear side switch S2*must be in position “I”.
7. switch on the load
* REMARK: For more information about switch S2, see section 3.6.
3.2.2 Operation in parallel
REMARK: For parallel operation of PWS inverters it is necessary to use parallel operation chokes at the
outputs of the inverters as shown in figure 1+2). The article codes of the parallel operation chokes are
listed in section 2.3 “Available options”.
1. make shure that the inverters to be paralleled are identical in type.
2. check the system wiring (polarity of DC- supply line, synchronous bus)
3. check that the inverters are switched off
4. connect DC input with open DC busbar fuses
5. check the wiring between the inverters (synchronization wires)
6. connect AC loads
7. close DC busbar fuses
8. switch on the units with front side switches (rear side switch S2 in position “0” for remote switch-
on function in combination with a static bypass switch UNB).
9. switch on the load
One of the paralleled inverters operates as master and synchronizes the other inverters to a given
frequency.
Note: The unit which first of all feeds in is the master. If the master unit fails or is switched off, another
unit overtakes the master function.
If paralleled inverters operate in combination with a static bypass switch (UNB), the UNB automatically
is the master. The connected inverters are synchronized by the UNB via the control wire SYNC-STAT.
For a faultless function it is important that the wiring between the inverters (and static bypass switch)
is correct.
The inverters connect themselves to the AC output (over an internal output-side contactor) not till
then the output voltage reaches the nominal value.
REMARK: Due to the connected parallel operation chokes in combination with the resistance of the
wiring the short circuit detection of the units will be affected.
For this application, it is recommended to check individually the short circuit behavior of the system.
Due to the voltage losses at the inductance of the parallel operation choke, the voltage deviation value
exceeds the specified data of the data sheet of the PWS.

Input voltage <85% (±2%) Vi nom.
LED “Vi<” = ON.
The module automatically undelayed
switches off. It automatically
switches on when the input voltage
reaches 103% (±2%) Vi nom. The
hysteresis prevents oscillating of the
automatic switch-off.
DC input voltage
Input voltage >128% (±2%) Vi nom.
LED “Vi>” = ON.
The module automatically undelayed
switches off (overvoltage protec-
tion). It automatically switches on
when the input voltage decreases to
125% (±2%) Vi nom.
AC output voltage Output voltage <90% Vout nom.
LED “ERROR” = ON.
The module automatically switches
off, time delay = 2.5s. An automatic

lows after 15s. Due to this the mod-
ule is continuous short circuit proof.
Over-
load/temperature*
Heat sink temperature of the power
amplifier of the inverter >90°C.
LED “OVERLOAD/TEMP.>” = ON.
The module automatically switches
off if the temperature does not de-
crease. It automatically switches on
when the heat sink cools down to
≤70°C.
* Possible reasons: Elevated ambient temperature, continuous overload (approx. 20-25%) or a defec-
tive fan. Overload capability: See section 6 “Technical specification”.
REMARK: Keep the maximum allowed overload time because the module does not automatically switch
off.
3.5 Potentiometer
Below the LED indicators the PWS-F is fitted with a potentiometer for fine adjustment of the AC output
voltage.
Potentiometer
With the potentiometer the AC output voltage can be fine adjusted
(e.g. for the compensation of voltage losses at the parallel opera-
tion choke). Adjustment range: ±2VAC.
Testjack
The output voltage can be measured at the testjack. Ratio= 1:100
(1V =100V). But it is recommended to measure the output voltage
at the output of the module with consideration of possible voltage
losses at the internal wiring and parallel operation choke.

3.6 Rear-side switch S2 (remote switch-on function)
The remote switch-on function is designed to switch on/off all paralleled PWS-F inverters simultane-
ously.
For this function the DC input voltage monitoring function of the static bypass switch UNB is used. If
the UNB detects “DC input voltage is okay” the signal for remote switch-on is sent via the wire con-
nected to pin 9 (pin 12 respectively) of the PWS connector.
In reverse: If the DC input voltage is not okay, the remote switch-off signal is sent.
With switch S2 (see figure 9)) fitted on the rear side of the PWS-F it is possible to enable/disable the
remote switch-on function depending on the intended use.
Figure 9) - Detail: Rear side switch S2
Switch 2 position “1”= remote switch-on function disabled. In this position, the module can be switched
ON and OFF with the front side switch S1.
Switch 2 position “O”= remote switch-on function enabled. In this position, the module can be remotely
switched ON and OFF by the static bypass switch UNB.
Table “Function of switch 1 and switch 2”:
Switch position of
S1 S2 Function
0 1 Module manually switched OFF, remote switch-on function disabled.
1 1 Module switched ON, remote switch-on function disabled (stand-alone mode)
0 0*Module manually switched OFF, remote switch-on function enabled.
1 0*Module switched ON, remote switch-on function enabled.
* REMARK: When the PWS is used as stand alone module, it can not be switched ON with S1 if the
position of S2 is “0”.
For a faultless remote switch on function it is important that the wiring between the inverters and
static bypass switch (remote switch on wire) is correct.
INFO: The PWS-F series is serially fitted with the rear side switch since August 2008 (date of
manufacture).
