GENERAL
INFORMATION
1.2 GENERATOR APPLICABILITY
These generators have been designed and manufac­
tured for supplying electrical power to recreational vehi­
cles. You should neither modify the generator nor 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 factory. 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 NFPA 70 (lat­
est edition), "National Electrical Code", Article
551, and NFPA 1192 (latest edition), "Standard for
Recreational Vehicles". The generator also must
have been installed in strict compliance with the
manufacturer's detailed installation instructions.
After installation, do nothing that might render
the unit In noncompliance with such codes, stan­
dards, and Instructions.
You can use this generator to supply electrical power for
operating 120/240-volt, single-phase, 60-Hertz, AC elec­
trical 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.
•------- M. CAUTION Mr—
A Do not overload the generator. Some installations
may require that electrical loads be alternated to
avoid overloading. Applying excessively high elec­
trical loads may damage the generator and short­
en its life. Add up the rated watts of all electrical
lighting, appliance, tool, and motor loads the gen­
erator 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
current) for starting than for continuous opera­
tion.
1.3 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 dam­
age to equipment and/or property. We suggest copying
and posting the “Safety Rules” in potential hazard areas
of the vehicle. Stress safety to all operators and poten­
tial operators of this equipment.
1.4 GENERATOR AC
CONNECTION SYSTEM
This generator is equipped with dual-stator AC power
windings.
These two-stator windings supply electrical
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 powers
120- and/or 240-volt AC electrical loads (Figure 1.1). It
can be rewired to connect 120-volt AC electrical loads
only. This procedure should be done by a Generac
Authorized Service Dealer or other qualified installer.
Refer to the installation portion of this manual for more
information.

♦ 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 minimum
Cetane number of 40. The diesel fuel must also 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 sepa­
rate fuel tank or “share” the vehicle’s engine fuel tank.
NOTE:
Some installations using a “shared” fuel tank may
have a generator fuel pickup tube that is shorter
than the vehicle’s engine pickup tube. Such an
arrangement causes the generator engine to “run out
of fuel”, while adequate fuel for the vehicle engine
remains 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
