5.1 PURPOSE ÄND SCOPE
OF THE MANUAL
These Installation Instructions have been prepared
especially for the purpose of familiarizing installers and
owners of the applicable equipment with the product's
installation requirements. Give serious consideration to
all information and instructions in the manual, both for
safety and for continued reliable operation of the equip­
ment.
Because of the different recreational vehicle models and
the variations between the models, it would be extremely
difficult, if not impractical, to provide detailed instruc­
tions for every possible installation. For that reason,
instructions and illustrations in this manual are general
in nature. Illustrations are not intended to serve as
detailed Installation blueprints.
The installation should comply strictly with all applica­
ble codes, standards and regulations pertaining to the
installation and use of this product. If any portion of
this manual appears to be in conflict with such codes,
standards
or regulations, the applicable codes, stan­
dards or regulations must take precedence over the
manual.
5.2 SAFETY
Before handling, installing, operating or servicing this
equipment, carefully read the "Notice to Installer” and
"Safety Rules” on Pages 18 and 19. Comply with all safe­
ty rules to prevent death, personal injury or damage to
equipment
and/or property. Stress safety to all
installers, operators and service technicians who work
on this equipment.

5.4 EQUiPMENT
DESCRIPTION
Instructions and information in this section pertain to
Generac
air-cooled generators. These generators are
designed specifically for installing in recreational vehi­
cles. They operate 120-volt, single-phase, 60-Hertz, AC
electrical loads that require 40.0 amps (gasoline) or
37.5 amps (LP fuel) at 120 volts.
5.5 GENERATOR ENGINE
OPERATING SPEED
The generator’s revolving field (rotor) is driven by a sin­
gle-cylinder, four-cycle engine through a pulley and drive
belt arrangement. The generator supplies 120 volts AC
at 60 Hertz when the rotor is operating at 3,600
rpm.The drive belt arrangement allows the engine to
operate at a lower speed than the rotor.
5.6 GENERATOR AC
CONNECTION SYSTEM
The generator is equipped with dual stator power wind­
ings as shown in Figure 1.1.
Figure 5.1 - 120-volt Single Voltage Connection
• The AC connection system on all air-cooled
PRIMEPACT series generators uses a GROUNDED
neutral.
• A separate green ground wire is connected to the
recreational vehicle’s junction box.
• For these PRIMEPACT units, loads connected across
T1 (red) to T2 (white), MUST NOT exceed 30
amperes or 3,600 watts, and loads connected across
T3 (black) and T2 (white) MUST NOT exceed 20
amperes or 2,400 watts each at 120 volts. The com­
bined loading of the two breakers should not exceed
5,500 watts.
NOTE:
Do NOT connect loads in excess of circuit
breaker ratings.
