GENERAL
INFORMATION
1.2 GENERATOIIAPPLIGIBILITY
These generators have been designed and manu­
factured for supplying electrical power for recre­
ational vehicles. You should not modify the gener­
ator or use it for any application other than for
what it was designed. If there are any questions
pertaining to its application, write or call the fac­
tory. Do not use the unit until you have been
advised by a competent authority.
DANGER
A For fire safety, the generator must have been
properly installed in compliance with ANSI
119.2-1975/NFPA 501C-1974, "Standard for
Recreational Vehicles, Part III - Installation of
Electrical Systems." The generator also must
have been installed in strict compliance with
the manufacturer's detailed installation instruc­
tions. After installation, do nothing that might
render the unit in noncompliance with such
codes, standards and instructions.
You can use this generator to supply electrical power
for
operating 120/240-volt, single-phase, 60 Hertz,
AC electrical loads. These loads can require up to
7,500 watts (7.5 kW) of power, but cannot exceed
62.5 AC amps of current at 120 volts, or 31.2 AC
amps at 240 volts.
---------- Mk CAUTION Jk------------------------
A Do not overload the generator. Some installa­
tions may require that electrical loads be alter­
nated to avoid overloading. Applying excessive­
ly high electrical loads may damage the genera­
tor and may shorten its life. Add up the rated
watts of all electrical lighting, appliance, tool
and motor loads the generator will power at
one time. This total should not be greater than
the wattage capacity of the generator. If an
electrical device nameplate gives only volts and
amps, multiply volts times amps to obtain watts
(volts X amps = watts). Some electric motors
require more watts of power (or amps of cur­
rent) for starting than
ifor continuous operation.
13 SAFETY
Before attempting to use the generator set, carefully
read
the “Safety Rules” section of this manual.
Comply strictly with these rules to prevent accidents
and damage to equipment and/or property. We sug­
gest copying and posting the “Safety Rules” in poten­
tial hazard areas of the vehicle. Stress safety to all
operators and potential operators of this equipment.
1.4 GENERATOR AC
CONNEQION SYSTEM
This generator is equipped with dual stator AC power
windings. These two-stator windings supply electri­
cal power to customer electrical loads by means of a
dual two-wire connection system. Note, however, that
the neutral is grounded.
The generator may have been installed so that it pow­
ers 120- and/or 240-volt AC electrical loads (Figure
1.1). It can be rewired to connect 120-volt AC electri­
cal loads only. This procedure should be done by a
Generac Authorized Service Dealer or other qualified
installer. Refer to the installation portion of this man­
ual for more information.

1.S SPECIFICATIONS
♦ 1.5.1 FUEL REQUIREMENTS
The generator is equipped with a diesel fuel system.
Use clean, fresh No. ID or No. 2D diesel fuel with min­
imum Cetane number of 40. It also must conform to
American Society of Testing and Materials (ASTM)
specifications. Never use any dirty or contaminated
fuel. When adding fuel, DO NOT overfill the tank. Allow
room at the top of the tank for fuel expansion.
Depending on the Installation, the generator may have
either a separate fuel tank, or it may “share” the vehi­
cle engine’s fuel tank.
NOTE:
Some installations using a “shared” fuel tank may
have a generator fuel pickup tube that is shorter
than the vehicle engine’s pickup tube. Such an
arrangement causes the generator engine to “run
out of gas” while adequate fuel for the vehicle
remain in the tank.
Also, appropriate care should be taken in applica­
tions where extremely low ambient temperatures
are possible to ensure the temperature of the
diesel fuel is not allowed to fall below levels where
“gelling” could occur.
