Section 1 – General Information
PRIMEPACT 50 and 70 (50Hz) Recreational Vehicle Generators
1.2 GENERATOR APPLICABILITY
These generators have been designed and manufac-
tured for supplying electrical power for recreational
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 a competent
authority.
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.
1.2.1 PRIMEPACT 70
Use this generator to supply electrical power for
operating 230-volt, single-phase, 50 Hertz, AC elec-
trical loads. These loads can require up to 7,000
watts (7.0 kW) of power, but cannot exceed 30.4 AC
amperes of current at 230 volts.
1.2.2 PRIMEPACT 50
Use this generator to supply electrical power for
operating 230 volt, single phase, 50 Hertz AC electri-
cal loads. These loads can require up to 5,000 watts
(5.0 kW) of power, but cannot exceed 20.8 amperes of
current at 230 volts.
Do not overload the generator. Some installa-
tions may require that electrical loads be alter-
nated to avoid overloading. Applying exces-
sively high electrical loads may damage the
generator 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 current) for starting than for continuous
operation.
1.3 INSTALLATION
This manual has been prepared under the assump-
tion that a competent, qualified technician installed
the generator into a recreational vehicle. We also
assume the installer complied with all applicable
codes, standards and regulations pertaining to instal-
lation.
Owners/Operators should make sure nothing is done
during installation that might render the unit unsafe
or in noncompliance with applicable codes standards
and instructions. They should be sure the unit has
been installed to allow adequate ventilation for cool-
ing and exhaust air.
1.4 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.
1.5 GENERATOR AC
CONNECTION SYSTEM
This generator set is equipped with dual stator AC
power windings. These two-stator windings supply
electrical power to customer electrical loads.
NOTE:
One side of the winding is grounded.
