Generac 0661-4 - 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
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 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.

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.

EQUIPMENT DESCRIPTION
Instructions and information in this section pertain to
Generac air-cooled generators — more specifically,
the installation of NP30 recreational vehicle genera­
tors. These generators are designed specifically for
installing in recreational vehicles.
ENGINE GENERATOR
OPERATING SPEED
The generators are driven by single-cylinder engines.
The engines drive revolving fields (rotors), high fre­
quency, permanent magnet alternators. The genera­
tors supply 120 volts AC at 60 Hertz. The generators
revolving fields are driven at a variable speed
depending on the instantaneous demand for power.
Computers
monitor that demand and adjust the
engine speed to provide adequate power to the con­
nected loads.
GENERATOR AC CONNECTION
SYSTEM
The generators are equipped with single voltage AC
connection systems. The following facts pertain to
such a connection system:
• On the units, the 120 volts, connections system is pro­
tected by a circuit breaker.
• The AC connection system on all air-cooled generators
use a GROUNDED neutral.
• A separate green ground wire is connected to the recre­
ational vehicle's junction box.
