5.1PURPOSE 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 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.

5.2SAFETY

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.

5.3STANDARDS BOOKLETS

Installation, use and servicing of this equipment should comply strictly with published standards, as well as the manufacturer's recommendations. The following stan- dards booklets (latest revision) are available from the sources indicated:

1.NFPA Standard 501C, “Standard for Recreational Vehicles,” available from the National Fire Protection Association, Batterymarch Park, Quincy, MA 02269.

5.4EQUIPMENT 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 55.0 amps (gasoline) or 51.7 amps (LP fuel) at 120 volts.

5.5GENERATOR 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.

5.6GENERATOR 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 — one load with a maximum total wattage requirement equal to the generator’s rated power output (in watts), and 120V across the generator output terminals. (See Fig. 5.1 below)

2)120/240 VAC loads — one load with a maximum total wattage requirement equal to the generator’s rated power output, and 240 V across the generator output terminals; or two seperate loads, each with a maximum total wattage requirement equal to half of the genera- tor’s rated power output (in watts), and 120 V across the generator output terminals. (See Fig. 5.3 on page 22)
