Electrical connection

Operating a Power Module on a non-grounded supply system/IT system
If the device is operated on a non-grounded line supply (IT system), the connection clip to
the basic interference suppression module must be removed.
To do so, loosen the two screws ("1" in the following diagram) and remove the connection
bracket. Once you have loosened the screws, turn the connection bracket to the side (to the
right) first and then pull it forwards out of the unit.
