5. Operation
5.1 Main switch
Before wiring the device, make sure that the main
switch is in position OFF „0“. Herewith, all poles are
disconnected from the mains voltage.
The main switch can be locked following EN81-80.
Before working on the device itself or on a tool connected
to it, the switch must be locked to prevent the device
against unintentional restart.
This can be done by retracting the power cable and
securing it against re-connecting or by locking the
main switch with a personal lock.
After having finished the wiring completely, switch
the device on with main switch in position ON „1“.
