Section 1 – General Information

Recreational Vehicle Generator

1.1PURPOSE 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 reliable operation of the equipment.

Because of the different recreational vehicle mod- els 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 appli- cable 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 prece- dence over the manual.

1.4EQUIPMENT DESCRIPTION

Instructions and information in this section pertain to air-cooled generators. These generators are designed specifically for installing in recreational 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.

1.5GENERATOR ENGINE

OPERATING SPEED

The generator’s revolving field (rotor) is driven by

asingle-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.

1.2SAFETY

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 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.

Figure 1.1 – 120-volt Single Voltage Connection

•The AC connection system on all air-cooled genera- tors uses a GROUNDED neutral.

•A separate green ground wire is connected to the recreational vehicle’s junction box.

•For these 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.
