1.1 PURPOSE AND SCOPE OF THE
INSTALLATION INSTRUCTIONS
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 seri-
ous 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 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 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,
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”. Comply
with all safety 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.
1.3 STANDARDS BOOKLETS
Installation, use and servicing of this equipment should comply
strictly with published standards, as well as the manufacturer's

1.4 EQUIPMENT DESCRIPTION
Instructions and information in this section pertain to air-cooled
generators. These generators are designed specifically for install-
ing in recreational vehicles. They operate 120-volt, single-phase,
60-Hertz, AC electrical loads.
1.5 GENERATOR ENGINE
OPERATING SPEED
The generator’s revolving field (rotor) is driven by a two-cylinder,
four-cycle engine through a pulley and drive belt arrangement. The
generator supplies 120 volts AC at 60 Hertz when the rotor is oper-
ating 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
These air-cooled 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.
Generators may be installed to provide the following outputs:
1. 120 VAC loads only — two loads each, with a maximum total
wattage requirement equal to half of the generator’s rated
power output (in watts), and 120V across the generator out-
put terminals (see Fig. 1.1).
2. 120/240 VAC loads — one load with a maximum total wattage
requirement equal to the generator’s rated power output, and
240V across the generator output terminals; or two separate
loads, each with a maximum total wattage requirement equal
to half of the generator’s rated power output (in watts), and
120V across the generator output terminals (see Fig. 1.3).
