Connection to the supply voltage
•
Before establishing the connection make sure the power supply is switched off.
•
Before commissioning, and also for brief measuring and test purposes, connect the PE protective
conductor
Fig. 4.4:
–
on the earthing screw of the motor controller housing
–
to pin PE [X9.5], power supply.
The cross section of the protective conductor at PE [X9.5] must correspond at least to the cross
section of the external conductor L [X9.1].
