PRIMEPACT 50 and 70 (50Hz) Recreational Vehicle Generators

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 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 pertain- ing 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 Generac air-cooled generators. These generators are designed specifically for installing in recreational vehicles. They operate 230-volt, single-phase, 50- Hertz, AC electrical loads that require 20.8 amps (PP50) or 30.4 amps (PP70).

1.5GENERATOR 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 230 volts AC at 50 Hertz when the rotor is operating at 3,000 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.

This generator set is equipped with dual stator AC power windings as shown in Figure 1.1. These two- stator windings supply electrical power to customer electrical loads by means of a dual two-wire connec- tion system. Note, however, that the neutral is grounded.
