6.5.2 Switchgear mains connection
CAUTION
Material damage due to incorrectly set mains voltage!
The switchgear can be operated at different mains voltages. The mains voltage is set
to 400V at the factory. To use another mains voltage, change the position of the
cable jumper before connection. If the wrong mains voltage is set, the switchgear
will be destroyed!
Insert the connection cable laid by the customer through the threaded cable connec-
tions and secure. Connect the wires to the terminal strip according to the connection
