Danger
It must be checked as to whether the Power Module is designed for the correct power supply
voltage - higher supply voltages may not be connected to the Power Module.
Danger
After connecting the line and motor feeder cables to the appropriate terminals, it must be
checked that the front covers (only frame sizes D and F) are closed and latched. Only then
may the power module be connected to the supply voltage.
Danger
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.
Danger
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.
Danger
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.
Measures according to EN 61800-5-1 must be taken (e.g. PE conductor (≥10 mm
an additional connection terminal for a PE conductor with the same cross-section as the
original PE conductor).
