7.6.6 Manually Charging the Closing Spring
• Check the operating state of the circuit breaker and the
mechanism:
- Closing spring discharged.
- Breaker either in closed or open position.
- Control voltage disconnected.
• Open the door of the mechanism.
• Using the hand crank (70.53), turn the gearing clockwise until the
spring position indicator shows "closing spring charged“.
• In this position the gearing is in idling position and can be turned
further.
• While the closing spring is being charged, the return stop
prevents the crank wheel from slipping backwards when manual
charging is interrupted or stopped.
• Close the cabinet door.
