@experts: Topic shared between DOCA0284, DOCA0285 and DOCA0266; indicate if comments do not apply to both guides

Closing Conditions

To close the circuit breaker, the following conditions must be met:

  • Circuit breaker is open (O).

  • Closing spring is charged.

  • The circuit breaker is ready to close, OK is displayed.

NOTE: An opening order always takes priority over a closing order. The circuit breaker cannot be closed while an opening order is being received. If OK is crossed-out on the ready-to-close indicator, an order to open is being received (either electrically or mechanically) and must be ended before OK can be displayed.
DANGER
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH
Do not re-close the device on an electrical fault. First inspect and, if necessary, repair the downstream equipment.
Failure to follow these instructions will result in death or serious injury.
