4.2.4 Switching on the motor side

Switching on the motor side is permissible for an emergency stop
as well as during normal operation.

Please note that when switched with the controller enabled, this
may cause the fault message OC1 (short circuit/earth fault). For
long motor cables, the fault current on the interfering cable
capacitances can become so large that the short circuit monitoring
of the device is triggered. In these cases, a motor filter is necessary
to reduce the fault currents (see page 43).
