Description
Figure 3: Main input connection scheme of cabinet
2.4 DC output
Before the cabinet is put into operation, the DC output
connection to the load application should be established.
!
Note
Take care of sufficient input cable cross section! We
recommend to use at least 150mm² or 2x 75mm² cross
section per output pole for the total 300A of the cabinet.
The load cables are directly screwed to the coppers bars
by M8 screws.
!
Note
Use M8 ring lugs
at the end of the load cables!
Danger to life!
Make sure that all units are switched off before
working on the DC output and that no output volt-
age is still present. Remove the protective cover
carefully!
After connecting the load or changing the con-
figuration, it is imperative to mount the protective
cover again!
3. Operation
3.1 Redundancy
Redundancy becomes active, if one or multiple units dis-
continue operation because of a defect or overheating.
The remaining units will continue to work in such a case,
but nominal power and current of the cabinet can not be
achieved anymore.
3.2 PV operation
The integrated photovoltaics option (PV) enables the device
to simulate solar panel behaviour and thus to run solar
inverter tests.
It is imperative to always adjust all ac-
tive units to the same set values and operation mode.
3.2.1 Manual control
Manual control of the parallel system is not recommended,
because the set values can not be adjusted simultane-
ously here.
3.2.2 Remote control
Identical set values on all units can be achieved by paral-
lel control via the analogue interfaces or optional, digital
interfaces. See example figures in section „4. Wiring sche-
matics“.
We recommend to use CAN digital interfaces, which feature
broadcast message type. It means, one command with
set value, for example current = 200A, is sent to all units
simultaneously.
