Operating the circuit-breaker panel
62 NXAIR / ≤ 40 kA 110-0134.9 / 14
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 charging the spring energy store manually, set the panel to local
control, for example by switching the local-remote switch to LOCAL
position.
Rhythmical noises
Turning the hand crank for charging the spring energy store in the circuit-breaker
causes rhythmical noises and low vibration.
