Danger: Electric Shock

Before connecting or disconnecting a load cable from the receptacles,
always turn the circuit breakers (MAIN CB, 15A, 30A) to [OFF] position. And
always stop engine, and remove the engine key. The person performing the
maintenance should always keep the key.

Ground the grounding terminal to the earth as set out in the manual. If left
unconnected by mistake or accident, it will be much more dangerous for
human than the NO-RELAY case, because leaking current inevitably goes
through the body. (Refer to『5-7. Earth Leakage Relay』)

Even though all the current leakage relays in the loads have been grounded
to the earth, the earth grounding terminal and the canopy should also be
grounded to the earth.

Grounding should be made after the engine is stopped.

If the current leakage breaker activates, repair the fault first.

Caution: Injuries

Be sure to connect to the receptacles, after confirming that all the switches
in the loads are positioned to [OFF].
