PURPOSE 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.
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

Instructions and information in this section pertain
to Generac Impact air-cooled generators — more
specifically, the installation of Impact-34 plus II and
IMPACT-36 plus II Recreational Vehicle Generators.
These generators are designed specifically for
installing in recreational vehicles.
ENGINE GENERATOR OPERATING
The generators are driven by gasoline-powered, sin-
gle-cylinder engines. The engines drive revolving
fields (rotors), high frequency, permanent magnet
alternators. The generators supply 120 volts AC at 60
Hertz with DC inverter. The generators revolving
fields are driven at a variable speed depending on the
demand for power. Computers monitor that demand
and adjust the engine speed to provide adequate
power to the connected loads.
