GENERAL INFORMA- TION

Generac NP-50LPG 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 any questions pertain- ing to its application, write or call the factory. Do not use the unit until you have been advised by a competent authority.

DANGER: FOR FIRE SAFETY, THE GENERATOR MUST HAVE BEEN PROPERLY INSTALLED IN

COMPLIANCE WITH (1) ANSI 119.2-1975/NFPA 501C-1974 “STANDARD FOR RECREATIONAL VEHICLES, PART III, “INSTALLATION OF ELECTRI- CAL SYSTEMS.” THE GENERATOR ALSO MUST HAVE BEEN INSTALLED IN STRICT COMPLIANCE WITH THE MANUFACTURER’S DETAILED INSTAL- LATION INSTRUCTIONS. AFTER INSTALLATION, DO NOTHING THAT MIGHT RENDER THE UNIT IN NON-COMPLIANCE WITH SUCH CODES, STAN- DARDS 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 4500 watts of (4.5kW) of power, but cannot exceed 37.5 AC amperes of current at 120 volts or exceed 18.8 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. We also assume the installer complied with all applicable codes, standards and regulations pertaining to installation.

Owners/Operators must make sure to do nothing that might render the installation unsafe or in noncompliance with applic- able codes, standards and instructions. They should be sure the unit has been installed to allow adequate ventilation for cool- ing and exhaust air.

SAFETY

Before attempting to use the generator set, carefully read GENERAL SAFETY RULES inside the cover of this Manual. Comply strictly with these RULES to prevent accidents and damage to equipment and/or property. We suggest that copy- ing and posting GENERAL SAFETY RULES in potential hazard areas of the vehicle. Stress safety to all operators and poten- tial operators of this equipment.

GENERATOR AC CONNECTION

SYSTEM

This generator set is equipped with dual stator AC 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 the unit powers 120 volt AC loads (Figure 1); or you can wire them to connect both 120 and/or 240 volt 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 information.
