Overvoltage on components:
In case of an earth fault in IT systems, incompatible overvoltages may occur in
the plant.
Possible consequences:
Destruction of the device.
Protective measures:
When using the devices in IT systems, separate the internal connection of
filters to the protective earth. For this purpose carry out the device−specific
measure as described.

Destruction of the device if the mains voltage is too high.
Observe the maximally permissible mains voltage.
Fuse the device correctly on the supply side against mains fluctuations and
voltage peaks.
When the controller is enabled, switching operations may lead to a response
of the controller monitoring functions.
The switching elements on the motor side must be rated for DC voltages
with U = 800 V.
