Generac Power Systems 00862-1 - Manual (Page 16)

GENERAL INSTALLATION INFORMATION
PURPOSE AND SCOPE OF MANUAL
These Installation Instructions have been prepared
especially for the purpose of familiarizing installers
and owners of the applicable equipment with the pro­
duct's installation requirements. Give serious consid­
eration to all information and instructions in the manu­
al, 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 on every installation possibility.
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 applica­
ble 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, stan­
dards,or regulations must take precedence over the
manual.
SAFETY
Before handling, installing, operating or servicing this
equipment, be sure to read carefully the “Notice to
Installer” and “Safety Rules” at front of this manual.
Comply with all SAFETY RULES to prevent death,
personal injury or damage to equipment and/or prop­
erty. Stress safety to all installers, operators and ser­
vice technicians who work on this equipment.
STANDARDS BOOKLETS
Installation, use and servicing of this equipment
should comply strictly with published standards, as

EQUIPMENT DESCRIPTION
Instructions and information in this section pertain to
Generac air-cooled generators. These generators are
designed specifically for installing in recreational vehi­
cles. They operate 120 volt, single phase, 60 Hertz, AC
electrical loads that require 46.0 amps at 120 volts.
ENGINE GENERATOR
OPERATING SPEED
The generator’s revolving field (rotor) is driven by a
single-cylinder, 4-cycle engine through a pulley and
drive belt arrangement. The generator supplies 120
volts AC at 60 Hertz when the rotor is operating at
3600
rpm.The drive belt arrangement allows the
engine to operate at a lower speed than the rotor.
GENERATOR AC CONNECTION
SYSTEM
The generator is equipped with dual stator power
windings as shown in figure 13.

OROUNDED
NEUTRAL
• The AC connection system on all air-cooled QP series
generators uses a GROUNDED neutral.
• A separate green ground wire is connected to the recre­
ational vehicle’s junction box.
• For these QP55 units, loads connected across T1 (red) to
T2 (white), MUST NOT exceed 30 amperes or 3600 watts
and loads connected across T3 (black) and T2 (white)
MUST NOT exceed 20 amperes or 2400 watts each at
120 volts. The combined loading of the two breakers
should not exceed 5500 watts.
IMPORTANT: DO NOT CONNECT LOADS IN EXCESS OF
CIRCUIT BREAKER RATINGS.
