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.

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.

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. NFPA 1192, “Standard for Recreational Vehicles”

(replaces ANSI A119.2/NFPA 501C), available

2. NFPA 70, “NFPA Handbook of the National

Electric Code,” available same as Item 1.

able from the State of California, Documents

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.

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.

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

• 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.
