z Be sure to use the frequency designated in the equipment incorporated in mercury lamp or
induction motor.
z The load incorporated in motor may require bigger power than the rated power consumption.
Therefore, consult with our authorized distributor or our engineering section to clarify.
z When connecting 2 or more sets to use, start the load one by one, not to start them simultaneously.
z When switching a Mercury bulb ON again, wait for 15 minutes (about) until it cools down.
z A Mercury bulb may flicker sometimes.

9-3 Operation
Danger : Electric Shock
z Before connecting or disconnecting a load cable from output terminals, always turn a circuit
breaker to 『OFF』 position.
z All the grounding terminals must be grounded. If one of them is not grounded, human body
may get a serious electric shock by leaked current. (Refer to『5-3 Earth Leakage Breaker』)
z Grounding should be made after the engine is stopped.
z Whenever the earth leakage breaker activates, you should repair the leaking place first of all.
Caution : Injuries
z Be sure to connect to output terminals or insert a plug to a receptacle, after confirming that all
the switches in the loads are positioned to 『OFF』.

Caution : Damage to the equipment or other properties
z In the event using the equipment to computers, microcomputers incorporated loads and precision equipment, there is a possibility for them to be mal-functioned or broken down.

z Be sure to use the power cord with crimping terminal to connect to output terminals.
z Volt meter reads the 3-Phase figures, even if the circuit breaker is positioned to『OFF』, when
the engine is driving.
After the engine starts (Refer to 『7-1 Initializing/Preparation』), operate the equipment as per the
following procedures.
① Turn off the power switch in the load, and then turn the circuit breaker to 『OFF』.
② Connect the load to the output terminals or receptacles.
③ Close the output terminal cover, after finishing connections and fix the cover with bolts.
④ Turn the circuit breaker to 『ON』.
⑤ When finishing the load operation, always turn the circuit breaker to『OFF』.
The Circuit Breaker
Caution : Injuries
z Be sure to turn off the power switch in the load when turning the circuit breaker to 『ON』,
when the circuit breaker has activated.
When the electric supply exceeds the rated output (overload), the circuit breaker activates to trip
off in order to shut off the circuit. When the load in operation stops, check the breaker. When the
circuit breaker is positioned intermediary『ON』and『OFF』, check if the earth leakage indication
lamp turns ON or not. In the case the lamp turning ON, refer to 『5-3 Earth Leakage Breaker』. In
the case the lamp NOT turning ON, follow the next procedures to restore the circuit breaker.
① Turn off all the power switches in the loads.
② Turn (Push) down the circuit breaker to『OFF』once and then turn (push) up the circuit
breaker to『ON』.

z Take care for overload, referring to 『9-2 Output Limitation』.
z When the output selector switch is positioned to ECO and AC power is used, the circuit
breaker trips off to shut down the circuit. Stop using AC power and follow the above procedures to restore the circuit breaker. (DGW311DM only)

10. Simultaneous Use of Welding and Generating
