QUIETPACT™ 75D 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 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.

1.2SAFETY

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, per- sonal injury, or damage to equipment and/or proper- ty. Stress safety to all installers, operators, and ser- vice technicians who work on this equipment.

1.3STANDARDS BOOKLETS

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

1.4EQUIPMENT DESCRIPTION

Instructions and information in this section pertain to Generac liquid-cooled generators, designed specifically for installing in recreational vehicles. The QUIETPACT 75D operates 120/240-volt, single-phase, 60-Hertz, AC electrical loads that require up to 62.5 amps at 120 volts or 31.2 amps at 240 volts.

1.5GENERATOR ENGINE

OPERATING SPEED

The generator’s two-pole revolving field (rotor) is dri- ven by a three-cylinder, 1.0-liter diesel engine. The generator supplies 120/240 volts AC at 60 Hertz, when the rotor is operating at 3,600 rpm. Engine speed is held nearly constant by a mechanical, fixed speed governor at 1,950 rpm.

1.6GENERATOR AC

CONNECTION SYSTEM

The generator is equipped with dual stator power windings, as shown in Figure 1.1.

Figure 1.1 – Connections for 120/240 Dual

Voltage

•The AC connection system uses a GROUNDED neutral. A separate green ground wire is connected to the recreational vehicle’s junction box.

•For this QUIETPACT™ unit, each stator winding can support 120-volt, 60-Hertz, AC electrical output (3,600 rpm). When the two stator windings are con- nected in series, the unit can generate an output of 240 volts AC.

NOTE:

Do NOT connect loads in excess of circuit breaker ratings.
