APPLYING LOADS TO GENERATOR
When applying electrical loads to the generator, observe these
guidelines:
• Before applying electrical loads, let the generator stabilize
and warm up for a minute or two.
• DO NOT overload the generator.
■ LETTING THE ENGINE STABILIZE
The generator supplies correct rated frequency and voltage
only at the proper governed speed. Some electrical appli¬
ances may be extremely sensitive to voltage and frequency.
Incorrect frequencies and/or voltages can damage those appli¬
ances.
If electrical loads are applied at reduced operating speeds, such
loads imposed on the engine when sufficient power is not avail¬
able may shorten engine life. Never turn ON electrical loads
until after the generator engine has started and stabilized
ON-speed.
■ DO NOT OVERLOAD THE GENERATOR
You can read the rated wattage/amperage capacity of your
generator on the generator data plate (see "Identification
Record" on Page 1).
Applying electrical loads in excess of the unit's rated capac¬
ity will cause the engine-generator to automatically shutdown.
To avoid overloading, add up the wattage of all connected elec¬
trical lighting, appliance, tool and motor loads. This total should
not be greater than the generator's rated wattage capacity.
• Most lighting, appliance, tool and motor loads indicate their
required watts on their nameplate or data plate. For light
bulbs, simply note the wattage rating of the bulb.
• If a load does not show its rated wattage, multiply that load's
rated VOLTS times AMPS to obtain WATTS.
• Induction type motors (such as those that run the vehicle's
furnace fan, refrigerator, air conditioner, etc.) need about 2-
1/2 times more watts of power for starting than for running
(for a few seconds during motor starting). Be sure to allow
for this when connecting electrical loads to the generator.
First, figure the watts needed to start electric motors in the
system. To that figure, add the running wattages of other
items that will be operated by the generator.
• Do not apply heavy electrical loads for the first two or three
hours of operation.
