VOLTAGE REGULATOR OPTION
The electronic voltage regulator controls the output of the generator by regulating the current into the exciter field.
The regulator has three screwdriver adjustable potentiometers that may be adjusted for voltage, stability and voltage
roll-off (U/F). The voltage regulator on your unit is adjusted before shipment from the factory. Contact Generac Mobile
Products for additional information before attempting to adjust the voltage regulator.
CUSTOMER CONVENIENCE RECEPTACLES
The control panel is equipped with multiple receptacles
for running accessories or tools from the generator.
Power is supplied to the receptacles any time the engine
is running and the main circuit breaker is switched to the
ON (I) position.
Note: Do not pull more than 1000W from each receptacle
when the lights are on. This will overload the generator
and cause the main circuit breaker to trip. Should the
breaker trip, switch off the lights, remove some of the load
to the receptacles and wait 10 minutes for the bulbs to
cool before turning them back on.
With all of the lights off, the full generator output may be used with the optional 240V twist-lock receptacle.
SHUTTING DOWN THE UNIT
Prior to shutting down the unit, check with personnel using power supplied by the unit and let them know the power
is going to be turned off. Make sure the power shut down will not create any hazards by accidentally turning off
equipment that needs to be kept on (pumps, compressors, lights, etc.).
When you have finished using the unit, proceed with shut down as follows:
1. Remove any loads from the receptacles.
2. Switch the individual circuit breakers for each light and each receptacle to the OFF (O) position.
3. Switch the main circuit breaker to the OFF (O) position.
4. Turn the Control Power switch to the OFF (O) position.
