NOTICE
Conflicting operation
Operating the contactor electrically is possible locally or from a central control.
The requirement of setting the panel to either local or remote control prevents
operating the panel locally and centrally at the same time.
Depending on the intended operating mode, set the panel to either local or
remote control (for example by switching the local-remote switch).
INFORMATION
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.
