7.3.3 The earth leakage breaker relay has activated
In the event the earth leakage breaker relay has activated, the earth leakage indicating lamp
Turns ON and the 3-Phase earth leakage breaker (lever) trips off to be positioned in the middle
between ON and OFF positions.
In the above condition, even though you stop the engine once and start it again, the 3-Phase
Circuit breaker (lever) does not restore to ON or OFF, and the reset button does not function,
because the device keeps detecting current leakage.
Stop the engine promptly and find the leakage point to repair. After repairing the leakage
point(s), proceed with the following restoration steps. (In the case the earth leakage indicating
lamp does not turn to ON simultaneously, the cause is Over-Loaded or Short-Circuit.)
Push the reset button or stop the engine.
Restore (Push-down) the 3-Phase circuit breaker (lever) and the 1-Phase circuit
breaker (lever) to OFF position.
By the above procedure, you can reset the breakers to ON positions.
