Generac NP-66LPG Recreational Vehicle Generator

GENERATOR APPLICABILITY

These generators have been designed and manufactured for
supplying electrical power for recreational vehicles. You should
not modify the generator or use it for any application other than
for what it was designed. If there are questions pertaining to
its application, write or call the factory. Do not use the unit until

you have been advised by a competent authority.

A

DANGER: FOR FIRE SAFETY, THE GENERATOR

MUST HAVE BEEN PROPERLY INSTALLED IN

COMPLIANCE WITH (1) ANS1119.2-1975/NFPA

501C-1974 "STANDARD FOR RECREATIONAL

VEHICLES", PART III, "INSTALLATION OF ELEC­

TRICAL SYSTEMS." THE GENERATOR ALSO

MUST HAVE BEEN INSTALLED IN STRICT COMPLI­

ANCE WITH THE MANUFACTURER'S DETAILED

INSTALLATION INSTRUCTIONS. AFTER INSTALLA­

TION, DO NOTHING THAT MIGHT RENDER THE

UNIT IN NON-COMPLIANCE WITH SUCH CODES,

STANDARDS AND INSTRUCTIONS.

You can use this generator to supply electrical power for oper­

ating 120/240 volts, single phase, 60 Hertz, AC electrical

loads. These loads can require up to 6600 watts of (6.6 kW)

of power, but cannot exceed 55 AC amperes of current at 120

volts or exceed 27.5 AC amperes at 240 volts.

CAUTION: Do not overload the generator. Some

installations may require that electrical loads be

alternated to avoid overloading. Applying exces­

sively high electrical loads may damage the

generator and may shorten its life. Add up the

rated watts of all electrical lighting, appliance, tool

and motor loads the generator will power at one

time. This total should not be greater than the

wattage capacity of the generator. If an electrical

device nameplate gives only volts and amps, multi­

ply volts times amps to obtain watts (volts x amps

= watts). Some electric motors require more watts
of power (or amps of current) for starting than for

continuous operation.

INSTALLATION

This Owner’s Manual has been prepared under the assump­
tion that a competent, qualified technician installed the

generator into a recreational vehicle. We also assume the

installer complied with all applicable codes, standards and reg­
ulations pertaining to installation.

Owners/Operators should make sure nothing is done during
installation that might render the unit unsafe or in noncompli­
ance with applicable codes, standards and instructions. They

should be sure the unit has been installed to allow adequate
ventilation for cooling and exhaust air.

SAFETY

Before using the generator set, carefully read GENERAL

SAFETY RULES inside the cover. Comply with these RULES

to prevent accidents and damage to equipment and/or prop­
erty. Generac suggests copying and posting the GENER/^L
SAFETY RULES in potential hazard areas of the recreational
vehicle. Safety should be stressed to all operators of this
equipment.

GENERATOR AC CONNECTION SYSTEM

This generator set is equipped with dual Stator a-c power
windings. These two stator windings supply electrical power
to customer electrical loads by means of a dual 2-wire con­

nection system. Note, however, that neutral is grounded.

The generator may have been installed so that units power 120

volts AC loads (Figure 1); or you can wire them to connect both

120 and/or

240

volts AC electrical loads. Be sure to install

jumper wire between the circuit breakers when reconnecting
for 120/240 volts. Refer to the Installation Manual for more infor­

mation.
