9-3. Operation
Danger: Electric Shock
●Before connection or disconnecting a load cable from the receptacle, always turn the circuit breakers
(3-P and 1-P) to OFF. And stop engine and remove the engine key. A person to perform it should
always keep the key.
●Ground every grounding terminal to the earth as set in the manual.
If even one of all is unconnected, by mistake or accident, it must be much more dangerous for human
body than NO CONNECTION, because a leaking current inevitably goes through the body.
●Even though all the current leakage relays in the loads have been grounded to the earth, the
grounding terminal and the bonnet (canopy) should be grounded to the earth.
●Grounding should be made after the engine is stopped.
●Whenever the current leakage breaker activates, you should repair the leaking point first of all.
Caution: Injuries
●Be sure to connect to the output terminals or insert a plug to a receptacle, after confirming that all the
switches in the loads are positioned at OFF.
●Be sure to select the correct frequency, designated in the loads.
Caution: Damage to the property – Aftermath
●Whenever connecting to use medical equipment or appliances, be sure to consult
with the medical equipment company, doctor or hospital personnel.
●Be sure to select the correct frequency, designated in the loads.
Otherwise the loads may be damaged.
