Power Modules
3.1 Power Modules Blocksize (PM340)
It must be checked as to whether the Power Module is designed for the correct power
supply - higher supply voltages may not be connected to the Power Module.
After connecting the line and motor feeder cables to the appropriate terminals, it must be
checked that the front covers (only frame sizes FSD and FSF) are closed and latched. Only
then may the Power Module be connected to the power supply.
It must be checked to ensure that suitable protective circuit-breaker/fuses - with the
specified rated currents - are installed between the line supply and the Power Module (refer
to Technical Data).
Only UL-listed copper cables may be used.
After disconnecting all the supply voltages, a hazardous voltage will be present in all
components for another 5 minutes. The cover for the terminals may only be opened after
this time has definitely elapsed.
When opening the protective cover, you must activate the release. A suitable tool (e.g.
screwdriver) must be used for this purpose.
Damaged components must not be used, otherwise this could result in secondary damage
or accidents.
The Power Modules conduct a high leakage current. Because of the high leakage current of
the Power Modules, a protective conductor must be permanently connected to the Power
Modules or permanently connected to the electrical cabinet.
Further, the following measures must be applied acc. to EN 61800-5-1:
Either conductor cross-sections ≥ 10 mm
the same cross-section as the first protective conductor.
