Panels with motor operating mechanism control
NOTICE
Maloperation
Racking the withdrawable circuit-breaker / circuit-breaker truck is only permissible
if the circuit-breaker is in OPEN position.
Check if the circuit-breaker is in OPEN position.
If required, switch the circuit-breaker to OPEN position before racking.
NOTICE
Maloperation
Racking the withdrawable circuit-breaker / circuit-breaker truck is only permissible
if the feeder earthing switch is in OPEN position.
Check if the feeder earthing switch is in OPEN position.
If required, switch the feeder earthing switch to OPEN position before
racking.
NOTICE
Maloperation
Electrically racking the withdrawable circuit-breaker / circuit-breaker truck is only
possible when both the high-voltage door and the control door are closed. If the
control door is open during an electrical racking procedure, the motor stops
immediately.
Do not open the control door during an electrical racking procedure.
NOTICE
Conflicting operation
Racking the withdrawable circuit-breaker / circuit-breaker truck 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).
