4 -3 Connecting the load

ELECTRIC SHOCK can kill.

■ Do not touch the output terminals during operation

to prevent decease due to electric shock.

* When a wiring work is required, be sure to turn OFF

the circuit breaker and stop the machine.

When operating the engine, close the output terminal cover.

Tighten the fixing bolts before operating the machine.

■ Do not use damaged cables to prevent electric shock.

Insufficient tightening of bolts will generate heat at

connections which may result in fire accidents.

* When connecting, make sure the connecting cables are

normal and connected firmly to the output terminals.

CAUTION

Connection to house wiring

■ Before connecting this machine to any building’s electrical system, a licensed

electrician must install an isoIation(transfer) switch.

* Serious injury or death may result without this transfer switch.
