GENERATOR FAMILIARIZATION
GENERATOR APPLICABILITY
Q-55G and Q-70G generators have been designed and
manufactured for supplying electrical power for recrea¬
tional vehicles. You should not modify the generator 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 factory. Do not use the unit
until you have been advised by competent authority.
DANGER: FOR FIRE SAFETY, THE GENERATOR
MUST HAVE BEEN PROPERLY INSTALLED IN
COMPLIANCE WITH (1) ANSI 119.2-1975/NFPA
501C-1974 "STANDARD FOR RECREATIONAL
VEHICLES", PART III, "INSTALLATION OF ELEC¬
TRICAL SYSTEMS." THE GENERATOR ALSO
MUST HAVE BEEN INSTALLED IN STRICT COM¬
PLIANCE WITH THE MANUFACTURER'S DE¬
TAILED INSTALLATION INSTRUCTIONS. AFTER
INSTALLATION, DO NOTHING THAT MIGHT
RENDER THE UNIT IN NON-COMPLIANCE WITH
SUCH CODES, STANDARDS AND INSTRUC¬
TIONS. _
You can use your generator set to supply electrical
power for operating one of the following electrical loads:
• Q-55G:
120 and/or 240 volts, single phase, 60 Hz
electrical loads. These loads can require up to 5500
watts (5.5 kW) of power, but cannot exceed 45.8 AC
amperes of current at 120 volts or exceed 22.9 AC
amperes at 240 volts.
• Q-70G:
120 and/or 240 volts, single phase, 60 Hz
electrical loads. These loads can require up to 7000
watts (7.0 kW) of power, but cannot exceed 58.3 AC
amperes of current at 120 volts or exceed 29.1 AC
amperes at 240 volts.
CAUTION: Do not overload the generator. Some
installations may require that electrical loads be
alternated to avoid overloading. Applying exces¬
sively high electrical loads may damage the gener¬
ator 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 capac¬
ity 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
operation.
INSTALLATION
This Owner's Manual has been prepared under the
assumption that a competent, qualified technician in¬
stalled the generator into an industrial vehicle. We also
assume the installer complied with all applicable codes,
standards and regulations pertaining to installation.
An INSTALLATION MANUAL was shipped with the
generator. That Manual contains manufacturer's in¬
structions and recommendations for installing the unit
into an industrial vehicle. After installation, installers
should forward the Installation Manual to Owners/Oper¬
ators for their information.
Owners/Operators have the responsibility to make sure
that nothing is done that might render the installation
unsafe or in non-compliance with applicable codes,
standards and instructions.
SAFETY
Before using the generator set, carefully read GEN¬
ERAL SAFETY RULES inside the cover. Comply with
these RULES to prevent accidents and damage to
equipment and/or property. Generac suggests copying
and posting the GENERAL SAFETY RULES to potential
operators of this equipment.
GENERATOR AC CONNECTION SYSTEM
These air-cooled Q Series generator sets are equipped
with dual stator AC power windings. These two stator
windings supply electrical power to customer electrical
loads by means of a dual 2-wire connection system.
The generator may have been installed so that units
only power 120 volts AC loads (Figure 1); or you can
wire them to connect both 120 and/or 240 volts AC
electrical loads. Be sure to remove the jumper between
the circuit breakers when connecting for 120/240 volts.
