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.
29
Caution
●The AC volt meter reads 3-P 200/200V apart from the circuit breakers position at ON or OFF
when the engine driving.
After the engine starts Refer to 7-1.Starting , operate as per the following procedures.
1 Turn the power switch off on the load.
2 Check and confirm the breakers position at OFF .
3 Select the correct frequency, designated in the loads.
4 Connect the loads to receptacle or terminals.
5 Close the terminal cover and fix it with the bolts.
6 Turn the breakers to ON .
■ Return -The circuit breaker has activated due to overload
Caution: Injuries
●Be sure to turn the power switch to OFF on the load when returning the circuit breaker to ON again,
when the circuit breaker has activated.
When the electric supply exceeds the rated output, the breaker activates to trip in order to shut down the
circuit. Check the breakers when the load stops operation.
ELCB lamp is to turn OFF in the case of overload shutdown. When the lamp keeps ON, refer to 5-6.
ELCB and Grounding .
When any breaker has activated, return the circuit breaker per the followings procedure.
1 Turn OFF all the power switches on the loads.
2 Once push down the breaker lever to OFF , push up the lever to ON .
Caution
●Take care for overload, referring to 9-2 Output Limitation
●The breaker activates when having used AC output in the selector switch at ECO position. In the
case stop using AC supply and return the breaker as above.
