Junction for grounding conductor
At delivery, the connectors are locked with protective cable glands. The cable
gland protects the motor from humidity, dirt and mechanical damage.

Protective cable glands
Remove the protective cable glands right before connecting the mating con‐
nector. Always use protective cable glands, if no plug-connector is connected
(e.g. storage, maintenance, ...).
Observe when connecting the flange socket:
●
Connect or disconnect plug connections only in de-energized, dry and
clean state.
●
Connect the motor with the ready-made connection cable.
