14.11 Opening the contactor manually
Conflicting operation
The requirement of setting the panel to either local or remote control prevents
operating the panel locally and centrally at the same time.
For operating the contactor manually, set the panel to local control, for
example by switching the local-remote switch to LOCAL position.
Unexpected switching noise and vibration
Operating the contactor causes a short loud noise and low vibration.
Expect switching noise and low vibration from inside the contactor.
Manual operation of the contactor is limited to manual opening of the contactor.
Manual closing of the contactor is not possible.
Contactor truck version with mechanical closing latch
Opening the contactor also opens the closing latch.
