1.1 PURPOSE AND 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 reli­
able operation of the equipment.
Because of the different recreational vehicle models
and the variations between the models, it would be
extremely difficult, if not impractical, to provide
detailed instructions 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
applicable codes, standards and regulations per­
taining to the installation and use of this product.
If any portion of this manual appears to be in con­
flict with such codes, standards or regulations, the
applicable
codes, standards or regulations must
take precedence over the manual.
1.2 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 safety rules to prevent death, per­
sonal injury or damage to equipment and/or prop­
erty. Stress safety to all installers, operators and
service technicians who work on this equipment.

1.4 EQUIPMENT DESCRIPTION
Instructions and information in this section pertain
to Generac air-cooled generators. These generators
are designed specifically for installing in rec|eation-
al vehicles. 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.
1.5 GENERATOR ENGINE
OPERATING SPEED
The generator’s revolving field (rotor) is driven by a
single-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.
1.6 GENERATOR AC
CONNECTION SYSTEM
The generator is equipped with dual stator power
windings as shown in Figure 1.1.
Figure 1.1 - 120-volt Single Voltage Connection
• The AC connection system on all air-cooled gen­
erators uses a GROUNDED neutral.
• A separate green ground wire is connected to the
recreational vehicle’s junction box.
• For the.se 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
combined loading of the two breakers should not
exceed 5,500 watts.
NOTE:
Do NOT connect loads in excess of circuit
breaker ratings.
