"UniVert 2" inverter  
Individual INV operation:  
Here an INV is supplied with DC and itself supplies the AC load. In  
the event of INV fault or switch-off, the load is no longer supplied.  
Parallel INV operation:  
In order to increase redundancy or performance, up to 8 INVs of the  
same type and the same output can be connected in parallel. Note  
that if one or several of the INVs fail, the remaining INVs take over  
the load. Overload of the remaining INVs can be prevented by  
choosing the right number of redundant INVs. If the number of INVs  
that fail or are switched off exceeds the number of available  
redundant INVs, the remaining INVs switch off together.  
When the INVs are switched back on by connecting the DC, they do  
not switch on their output contactors at the same time until a sufficient  
number of INVs (in accordance with the redundancy setting) are  
available to take over the load.  
INVs for parallel operation need a choke between INV output and  
busbar.  
Individual or parallel operation with SBS:  
If one or more INVs are combined with an SPS, switchover of the  
loads from the mains to the INV and vice versa is possible without  
any interruption. With parallel operation systems, the load is  
distributed to the remaining INVs if one or several INVs fail. The  
system may switch over to the mains when a voltage drop occurs on  
the load busbar as a result of the failure of one INV, or if the number  
of INVs still operating is insufficient (redundancy setting). In order to  
switch the load back from the mains to the INVs, n-R INVs must be in  
operation (where R = redundant INVs).  
2.2  
Function of the System  
Individual INV operation:  
The INV as an individual unit supplies the loads. If it is switched off or  
disturbed, either by internal faults of the INV or by failure of the  
DC supply or by a DC voltage deviation, the AC loads are no longer  
supplied. The INV is not synchronised with the mains or other  
AC voltage sources. The INV can be connected to the DC voltage  
using a switching device on the input (miniature circuit-breaker,  
contactor). An internal softstart device limits the current to values  
below the rated current. If the INV is switched to the DC, the control  
unit starts operating. The INV supplies the output voltage if the unit is  
additionally switched on using the ON/OFF switch. If the supplying  
mains fails, the battery of the power supply system is discharged  
(also) by the INV. When the DC undervoltage monitoring value is  
reached, the INV is switched off. If the battery is charged after the  
mains voltage has returned, the INV is automatically started when a  
limit value of the DC undervoltage monitoring is exceeded.  
Page 11 of 42  
8000012364 BAL, en  
 
"UniVert 2" inverter  
Parallel INV operation:  
Prerequisite for parallel operation is that the INVs on the DC and AC  
side are connected in parallel, interconnected via CAN bus (16-pin,  
X7) and correctly addressed. The general behaviour of an individual  
INV is as described in the previous paragraph.  
The loads are only supplied with voltage when n-R INVs are switched  
on. The K7 output contactors of the INVs switch on simultaneously.  
The load is distributed equally to all the INVs in operation. If an INV is  
switched off or becomes faulty, the remaining INVs supply the load.  
The INVs are not synchronised with the mains.  
When the DC undervoltage monitoring value is reached, the INVs are  
switched off. If the battery is charged after the mains voltage has  
returned, the INVs are automatically started when a limit value of the  
DC undervoltage monitoring is exceeded. The K7 output contactors of  
the INVs are switched on when n-R INVs are in operation.  
In order to be able to remove one INV from the interconnected  
system for maintenance or repair work, we recommend providing a  
DC and an AC fuse for each INV.  
Individual or parallel operation with SBS:  
Prerequisite for operation with SBS is that the INV and SBS are  
connected in parallel on the AC side, interconnected via  
CAN bus (X7) and correctly addressed. The general behaviour of an  
individual INV is as described in the two previous paragraphs.  
Under normal conditions, the INVs are operating synchronously with  
the mains and supply the AC loads. In the event of a voltage drop on  
the load busbar caused by the short circuit of an AC load or the  
failure, switch-off or overload of the INVs, the thyristor contactor of  
the SBS is fired and the K7 output contactors of the INVs are  
switched off. The loads are supplied by the mains. When the required  
number of INVs is available again, the loads are switched back from  
the mains to the INVs without interruption. If the SBS is blocked, e.g.  
because of mains voltage deviations, it is not possible to switch from  
INV to mains or vice versa.  
In order to be able to disconnect the SBS from the mains and the  
AC busbar for maintenance or repair work, we recommend providing  
an AC fuse for both sides and supply the loads via the manual  
bypass.

Description of the INV  
Its electronic high-performance components make the INV suitable  
for universal applications. It has a very high degree of operational  
reliability, optimum efficiency and excellent communication capability  
with other systems thanks to integrated interfaces.  
The control electronics of the INV have been designed on the basis of  
state-of-the-art microcontroller technology. By using parameters in  
the software, the main unit characteristics are determined.

Figure 2 illustrates the principle of an INV.  
In normal operation, the load is supplied "Online" by the INV. With  
systems comprising several parallel INVs, the load current is divided  
in accordance with the number of INVs. Depending on the system  
design, a power supply using up to 8 INVs can be realised. In addition  
to the parallel operation of several INVs, the reliability of supply can  
be further increased by integrating a static bypass switch, SBS. In the  
event of a failure of several INVs, switchover to the mains takes place  
without any interruption. Apart from power cabling, a bus line is  
required for control purposes between the units for systems  
comprising several INVs (and SBSs). The bus line has to be  
terminated at both ends with a resistor.  
ATTENTION:  
This INV must not be connected in parallel to the mains on the output  
side!  
2.4  
Principle of Operation of the INV, Electrical  
After connection of the DC voltage, the DC filter capacitors are  
charged via the softstart device. The control unit activates a bridging  
contactor as soon as the capacitor charging process is finished. The  
DOU displays measured values (output voltage/output current) on the  
LCD and the unit status via LEDs. The INV is switched on using the  
ON/OFF switch on the DOU. When the INV has been switched on, it  
can be started or stopped by connecting or disconnecting the  
DC voltage supply.  
The transistor INV set, pulsed with approx. 20 kHz, transforms the  
direct voltage into a single-phase sinusoidal AC voltage. The voltage  
is transformed electrically isolated to the required AC output voltage  
using a transformer. The secondary voltage is led to the load  
terminals via the AC filter, a miniature circuit-breaker, a current  
transformer and the INV output contactor. The stabilised output  
voltage of the INV is short-circuit-proof and can supply loads from  
capacitive through ohmic to inductive, as well a non-linear loads with  
a high crest factor. The INV also supplies high starting currents for  
motor loads. Refer to chapter "Technical data" for the exact  
specifications. The entire control and monitoring process is carried  
out using a microprocessor. LEDs and relays show the unit status,  
whilst output voltage and output current are displayed on an LCD.  
INVs for parallel operation need a choke between the INV output and  
the busbar. When several INVs are operated in parallel, or one or  
more INVs are operated with an SBS, a CAN bus is required between  
the units for control purposes. An additional CAN bus allows the unit  
to be integrated in a power supply system and connected to a central  
control and monitoring unit (PSM).  
With individual units, the INV immediately starts after actuating the  
ON/OFF switch. With an INV with SBS and presence of the mains,  
the INV starts immediately, but the output contactor is only switched  
on after synchronisation with the mains. With systems comprising  
several INVs, these synchronise to the mains and then jointly switch  
on the output contactor. The INV can be switched off in every  
operating status without delay using the ON/OFF switch.

2.5  
Description of the SBS  
Its electronic high-performance components make the SBS highly  
overload-resistant and thus capable of quickly eliminating load short  
circuits.  
The SBS can be used as the central SBS for parallel operation of up  
to 8 INVs.  
Another outstanding characteristic of the SBS is its communication  
capability with other systems via integrated interfaces.  
The control electronics of the SBS have been designed on the basis  
of state-of-the-art microcontroller technology. By using parameters in  
the software, the main unit characteristics are determined.

Figure 3 illustrates the principle of an SBS.  
In normal operation, the SBS is not fired, the load is supplied "Online"  
by the INV or INVs. If the supply of the load is no longer guaranteed  
by the INVs or the load voltage has dropped below a permitted value  
due to a load short circuit, the load is switched over to the mains  
without interruption.  
Apart from power cabling, a bus line is required for the SBS for  
process control purposes between the INV/INVs and the SBS. The  
bus line has to be terminated at both ends with a resistor.

2.6  
Principle of Operation of the SBS, Electrical  
If the SBS is supplied by connecting the mains or the load voltage,  
the corresponding operating status is automatically activated after  
3 to 5 seconds.  
With mains operation, the DOU displays load voltage and SBS  
current. With all other operating statuses, in addition to the load  
voltage the corresponding status (ready, blocked, fault) is displayed.  
The toggle switch on the DOU serves exclusively to acknowledge  
SBS faults.  
The SBS control unit continually monitors the load voltage and, in the  
event of a load voltage deviation, initiates switchover of the loads  
from the INV/INVs to the SBS without interruption. Then the loads are  
automatically switched back to the INV/INVs. The thyristors of the  
SBS only quench when the supply of the loads is guaranteed by the  
activation of the output contactors of the INV/INVs.  
When the SBS is fired, both antiparallel thyristors are triggered over  
the whole period ensuring reliable operation of the SBS in the entire  
range from inductive to capacitive load.  
The entire control and monitoring process is carried out using a  
microprocessor. LEDs and relays show the unit status, whilst the  
output voltage and output current are displayed on an LCD. If the  
SBS is operated with one or more INVs connected in parallel, a CAN  
bus is required between the units for control purposes. An additional  
CAN bus allows the unit to be integrated in a power supply system  
and connected to a central control and monitoring unit (PSM).

Function of the Inverter  
For technical data or unit settings, refer to the Technical Data Sheet  
in chapter 8.  
3.1  
DC Input  
The inverter is operated with 48 V (or 60 V) DC voltage. The input  
voltage is fuse-protected outside the INV. For details, refer to the  
technical data.  
An integrated softstart device limits the making current of the inverter  
to a value smaller than the rated input current. The input voltage is  
continuously monitored. (See chapter 3.3.)  
3.2  
3.3  
AC Output  
The INV output voltage is regulated to 230 V 50 H (see chapter 3.9)  
and monitored (see chapter 3.5). With an output voltage present and  
the INV in operation, the green LED lights up "UO OK".  
DC Input Monitoring System  
If a value falls below the "DC undervoltage, switch-off" threshold, the  
INV is immediately switched off. If the input voltage rises above the  
acknowledgement value, the INV is switched back on. If the  
monitoring system is triggered, the red "UI<" LED lights up.  
It the "DC overvoltage, switch-off" threshold is exceeded, the red  
"UI>" LED lights up and the INV is immediately switched off. If the  
value falls below the "DC overvoltage, switch-off" acknowledgement  
value, acknowledgement is made after a delay of 15 seconds.  
3.4  
3.5  
Temperature Monitoring System  
Overtemperature is signalled by the red "ϑ>" LED if the heat sink  
temperature exceeds critical values. The faulty unit switches off after  
40 seconds. Acknowledgement is made when it has cooled down.  
Overtemperature can result from e.g. high ambient temperature,  
constant overload of the INV or from fan failure.  
Output Voltage Monitoring System  
The INV output voltage is regulated to 230 V 50 Hz (see chapter 3.9)  
and monitored. With an output voltage present and the INV in  
operation, the green "UO OK" LED lights up. When the output voltage  
drops below 90% of the rated value, e.g. due to overload, short circuit  
or the triggering of a miniature circuit-breaker, the INV switches off  
after 2.5 seconds. The unit is not automatically switched back on.  
3.6  
Monitoring of Functions  
After connecting the input voltage, the self-test of the microcontroller  
control system is carried out automatically.  
Page 17 of 42  
8000012364 BAL, en  
 
"UniVert 2" inverter  
3.7  
3.8  
ON/OFF Switch  
The inverter is set ready for operation using the DOU switch on the  
front panel. The monitoring functions with their respective messages  
are only active when the inverter is switched on. After switch-off, all  
faults are acknowledged. The settings of the DIL switches are only  
accepted if the unit is switched off!  
CAN Bus Interfaces X6 / X7  
The unit can be controlled and monitored using the 10-pin CAN bus  
connector X6 if the INV is installed in a power supply cabinet with  
PSM control unit.  
The CAN bus connector X7 has no significance if one inverter in  
single operation operated without SBS. Both ends of the bus have to  
be connected to a terminating resistor when several INVs are  
operated in parallel!  
For operation with SBS, only the end of the bus on the INV must have  
a terminating resistor connected; a bus terminating resistor is  
integrated in the SBS! (See Figure 1.)  
3.9  
DIL Switch  
An 8-pin DIL switch is arranged below the LCD. All settings of /  
changes to the DIL switch are only activated after the INV has been  
switched off using the ON/OFF switch. It is counted from the left S2.1  
to the right S2.8, switches that are pushed in at the bottom signify  
"open"! The setting of the switches is shown on the display as a  
check whenever a change is made; 0 = open; 1 = closed.  
Switches S2.1, S2.2 and S2.3: Number of parallel INVs in the  
system  
The settings must be the same on all INVs and the SBS!

INV output miniature circuit-breaker  
The unit is equipped with a liquid-crystal display. When the unit is  
switched off, the LCD shows "OFF", when the unit is switched on it  
shows the INV output voltage and output current. While the INV starts  
up and output contactor K7 is still switched off, "READY" is signalled.  
In the event of a fault, the 1st display row shows "FAULT" and the  
2nd display row shows the type of fault.  
The INV voltage and current values are displayed with three decimals  
before and one decimal after the decimal point. The display accuracy  
corresponds to class 1 with respect to the rated output value of the  
unit.  
Remote signalling is carried out by means of potential-free contacts  
via a Combicon connector on the front of the unit.  
Assignment of the signal terminals:  
INV fault:  
In the event of a signal, X10.2 – X10.3 or X3.2 – X3.3 close.  
No fault: X10.2 – X10.1 or X3.2 – X3.1.  
When the INV is disconnected from the power supply (no DC supply),  
a fault is signalled!  
The remote signals are designed for safe isolation. The minimum load  
should not be below 12 V and 0.1 A.

Function of the SBS (optional)  
For the technical data or unit settings, refer to the chapter “Technical  
Data”.  
4.1  
Operating Statuses  
The following operating statuses are possible:  
"PowerUp":  
Status after PowerUp or Reset. The control system checks the  
ambient conditions.  
"on":  
Mains operation: The SBS supplies the load.  
"ready":  
In the event of load voltage deviation or INV failure / switch-off, the  
SBS takes over the load without interruption, i.e. the SBS control  
system switches over to the "on" operating status.  
"blocked":  
The SBS control unit is blocked. In the event of load voltage deviation  
or INV failure / switch-off, the SBS does not take over the load, i.e.  
the SBS control system remains in the "blocked" operating status.  
The operating status "blocked" is activated in the event of mains  
failures or phase deviations.  
"Fault":  
A fault has occurred in the SBS. This fault must be remedied and  
acknowledged using the Reset button.  
ATTENTION:  
If the INV is switched off in the event of a blocked or faulty SBS, the  
loads are no longer supplied with power.  
4.2  
Switchback Attempts  
Should the load voltage deviate excessively e.g. due to overload of  
the INVs or load short circuits (see chapter 4.4), the loads are  
automatically switched over to the SBS without interruption. Then the  
loads are also automatically switched back to the INV. It this  
switchback attempt fails, the SBS continues to supply the loads. After  
3 unsuccessful switchback attempts within 1 minute, the INV is  
switched off and the loads remain supplied by the SBS.  
Page 21 of 42  
8000012364 BAL, en  
 
"UniVert 2" inverter  
4.3  
AC Mains Input (X1)  
The SBS is connected to a 230 V AC mains.  
The input voltage is fuse protected outside the SBS. For details refer  
to the technical data.  
The input voltage is continuously monitored (see chapter 4.4).  
When the mains voltage is present, the green "mains present" LED  
lights up.  
4.4  
4.5  
AC Busbar (X2)  
The AC busbar is either supplied by the INV output voltage or the  
SBS output voltage which corresponds to the SBS circuit voltage.  
The INV output voltage is regulated to 230 V 50 H (see chapter 3.9)  
and monitored (see chapter 3.5).  
The load is only switched over to the SBS circuit if it lies within the  
defined tolerances and if a load voltage deviation is detected.  
AC Mains Monitoring System  
When the mains voltage is no longer within the tolerance range, the  
"mains present" LED goes off.  
The SBS changes the operating status from "ready" to "blocked".  
If the SBS is fired, the operating status does not change!  
The acknowledgement is carried out automatically as soon as the  
mains voltage is back within the tolerance range. The green "mains  
present" LED is lit, the SBS changes from "blocked" to "ready".  
4.6  
4.7  
AC Busbar Monitoring System  
If the load voltage leaves the tolerance range, the load is switched  
over to the SBS circuit without interruption. For this switchover, the  
SBS must be in the "ready" operating status.  
Temperature Monitoring System  
Overtemperature is signalled by the red "collective fault" LED if the  
heat sink temperature exceeds critical values. Acknowledgement is  
made when it has cooled down.  
Overtemperature can result from e.g. high ambient temperature,  
constant overload of the SBS or from fan failure.  
4.8  
4.9  
Monitoring of Functions  
After connecting the input voltage, the self-test of the microcontroller  
control system is carried out automatically.  
Reset Button  
The Reset button is used to acknowledge SBS faults. The Reset  
button must also be pressed to accept the settings of the  
DIL switches.  
Page 22 of 42  
8000012364 BAL, en  
 
"UniVert 2" inverter  
4.10  
CAN Bus Interfaces (X6, X7)  
The unit can be controlled and monitored via the 10-pin CAN bus  
connector X6, if the SBS is installed in a power supply cabinet with  
PSM control unit.  
The CAN bus connector X7 is always required for communication  
with the INV when operated with SBS. In this case, only the end of  
the bus on the INV must have a terminating resistor connected; a bus  
terminating resistor is integrated in the SBS! (See Figure 1.)  
4.11  
DIL Switch  
An 8-pin DIL switch is located below the LCD. All settings of/ changes  
to the DIL switch are only activated at mains operation, i.e. when the  
operating status is "on". Also press the Reset button to take over the  
settings of the DIL switches. It is counted from the left S3.1 to the  
right S3.8, switches that are pushed in at the bottom signify "open"!  
The setting of the switches is shown on the display as a check  
whenever a change is made; 0 = open; 1 = closed.  
Switches S3.1, S3.2 and S3.3: Number of parallel INVs in the  
system  
The settings must be the same on all INVs and the SBS!  
Example: 4 INVs are in the system, at least 3 INVs should run,  
i.e. 1 INV is redundant: S3.1=0; S3.2=1; S3.3=1; S3.7=0; S3.8=1

via a Combicon connector on the front of the unit.  
Assignment of the signal terminals:  
SBS fault:  
In the event of a signal, X4.2 – X4.3 close, no fault: X4.2 – X4.1  
When the SBS is disconnected from the power supply (no mains /  
INV supply), a fault is signalled!  
INV operation:  
In the event of a signal, X4.4 – X4.5 close  
The remote signals are designed for safe isolation. The minimum load  
should not be below 12 V and 0.1 A.  
4.13  
Operating modes  
Two operating modes can be selected using the DIL switches  
(see chapter 4.11).  
Switchover without gap:  
The switchover from INV to SBS is always carried out without  
interruption. If the INV and SBS circuit are not synchronous, the SBS  
blocks. If the INV is switched off due to asynchronism or if it fails, the  
load is not supplied by the SBS.  
This operating mode is set ex works and is recommended.  
NOTE:  
If the mains are poor or the SBS circuit is supplied by a diesel  
generator for example, the SBS can be temporarily blocked due to  
frequency deviations.  
i

8000012364 BAL, en  
"UniVert 2" inverter  
Switchover with gap:  
The switchover from INV to SBS is carried out without interruption if  
the INV and SBS circuit are synchronous. If the INV and SBS circuit  
are not synchronous, the SBS does not block in this operating mode.  
If the INV is switched off due to asynchronism or if it fails, the load is  
supplied by the SBS after a load voltage gap of 140 ms.  
NOTE:  
If the operating mode "Switchover with gap" is selected, the  
connected loads must be able to withstand a gap of 140 ms and a  
phase shift that might follow.

Start-Up  
5.1  
Installation  
When installing the INV, the following regulations must be observed:  
The INV has been designed for use in a dry room, practically free  
of dust.  
It is imperative to observe the specifications concerning ambient  
temperature and site altitude (see chapter “Technical Data”).  
Severe dust accumulation or a chemically aggressive atmosphere  
are not permissible; the system must be especially protected  
against conductive, humid dust deposits and condensation.  
The INV functions with forced air cooling. The supply air  
temperature must not exceed 45°C. The power loss of an INV is  
below 340 W at rated load.  
The inverter must be installed in suitable module racks.  
5.2  
Connection  
Before connecting the unit to the DC supply, ensure that the voltage  
values given on the nameplate correspond to the supplied voltages.  
The load is connected using terminals X2 (L1, N) on the front of the  
unit. The DC supply is connected using terminals X1 (L-, L+). The  
INV has to be earthed using a separate PE connection on the front of  
the unit. The cross-section of the PE conductor must be chosen in  
acc. with VDE 0100 Part 540 depending on the type of installation.  
The discharge current lies below 3.5 mA. Prior to start-up, a  
PE conductor connection must be established.  
With earthed DC systems, only the pole of the INV DC  
connection that is not earthed needs protection.  
Observe correct polarity of the DC lines.  
The load current must be checked before connecting the load; a  
permanent overload is not permissible and has a very negative  
impact on the reliability and the service life of the unit.  
DIL switch (see chapter 3.9 or chapter 4.11)  
CAN bus (see chapter 3.8 or chapter 4.10)  
Remote signals (see chapter 3.10 or chapter 4.12)  
5.3  
Connecting the Loads / DC / Mains  
When all lines have been connected completely, proceed as follows:  
Individual INV operation:  
Switch off the INV, switch on miniature circuit-breaker F1  
Connect the DC supply (The INV has a softstart device that limits  
the charging current in the input capacitors to a value below the  
rated current of the unit.)  
Switch on the INV  
Connect the load  
Page 27 of 42  
8000012364 BAL, en  
 
"UniVert 2" inverter  
Parallel INV operation:  
Switch off the INV, switch on miniature circuit-breaker F1  
Set the DIL switches  
Insert the AC fuses  
Connect the DC supply  
Switch on all INVs one after the other  
(The output contactors K7 of the INVs start at the same time as  
soon as n-R INV have been switched on)  
Connect the load  
Individual or parallel operation with SBS  
Switch off the INVs, switch on miniature circuit-breaker F1  
Set the DIL switches (INV and SBS)  
Engage the AC fuses (INV output)  
Engage the AC mains and output fuses of the SBS  
Disconnect the manual bypass  
Connect the load  
Connect the DC supply  
Switch on all INVs one after the other  
(The K7 output contactors of the INVs start at the same time as soon  
as the last INV has been switched on and the INVs have  
synchronised to the mains.)  
NOTE:  
Before switching on the INVs in parallel operation, or the SBS,  
make sure the setting of the DIL switches is correct (see  
chapters 3.9 and 4.11)!  
INVs in parallel operation must be set to the same output voltage,  
to the same number of INVs in the system and to different  
addresses!  
i
5.4  
Disconnection  
Even when switched off, the inverter can still be live due to charged  
capacitors and external signals. For this reason the terminals must be  
tested prior to dismantling the unit to ensure that they are  
de-energised.  
The capacitors can be discharged via an external resistor on  
terminals X2 or X1: L+ and L-.  
Switch off the INV  
Switch off the AC fuses, if present  
Switch off the DC supply  
Disable interfaces X6, X7, X3  
Disconnect earthing  
NOTE:  
Before switching off an INV in the parallel system, check whether  
the remaining INVs can take over the entire load. If necessary, the  
load current must be reduced by switching off individual loads!

Maintenance  
Attention! Disconnect the unit from the power supply prior to all  
maintenance work. Always observe the safety instructions!  
(See chapter 1.)  
The INV consists of state-of-the-art components which are almost  
non-wearing. We do, however, recommend regular visual and  
functional tests of the unit to maintain its continuous availability and  
operational reliability.  
When visually inspecting the unit, check whether:  
there is any mechanical damage or foreign bodies are present,  
any conductive dirt or dust has accumulated in the unit, and  
whether  
accumulation of dust affects heat supply and dissipation.  
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. The unit must not be operated in  
an aggressive atmosphere.

Troubleshooting  
Attention! All work on the unit may be carried out by specially  
trained qualified personnel only. Always observe the safety  
instructions! (See chapter 1.)  
7.1  
No Output Voltage or Output Current Present  
(with connected load)  
Individual INV operation:  
DC present and correct polarity?  
Are the LCD and the fan working? (Control unit is supplied with  
power)  
Is the INV switched on?  
Is the miniature circuit-breaker F1 switched on?  
Has a monitoring system responded?  
(Switch the INV OFF and back ON)  
With INVs in parallel operation: (additionally)  
LCD shows output voltage but no current:  
AC fuse faulty? Check output voltage of the unit  
INV does not synchronise and does not switch on the output  
contactor  
For systems with SBS: (additionally)  
LCD shows output voltage but no current:  
INV does not synchronise and does not switch on the output  
contactor  
Is the SBS blocked?  
If all aforementioned points are OK, proceed as follows:  
Disconnect the unit and disassemble it (see chapter 5.4)  
Unscrew the cover  
Observe the safety instructions!  
Check fuse F1 on printed circuit board A3.1 (softstart)  
Check fuse F100 on printed circuit board A17  
(INV interface, auxiliary power supply)  
Check fuse F1 on printed circuit board A17  
(INV interface, 24 V for fan, relay, INV control)  
Check plug connections for correct position  
It the fault cannot be eliminated, return the unit to the works for repair  
enclosing a fault description.  
7.2  
Output Voltage Deviation  
Did the INV cause the output voltage deviation?  
Is the unit running with current limiting due to overload?  
Reduce the load!
