Section 1 – General Information

PRIMEPACT 66G and 66LP Recreational Vehicle Generators

1.2GENERATOR APPLICABILITY

These generators have been designed and manufac- tured 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 pertaining to its application, write or call the factory. Do not use the unit until you have been advised by competent authority.

For fire safety, the generator must have been properly installed in compliance with ANSI 119.2-1975/NFPA 501C-1974, “Standard for Recreational Vehicles, Part III – Installation of Electrical Systems.” The generator also must have been installed in strict compliance with the manufacturer’s detailed installation instruc- tions. After installation, do nothing that might render the unit in noncompliance with such codes, standards and instructions.

You can use your generator set to supply electrical power for operating one of the following electrical loads:

PRIMEPACT 66G: 120 and/or 240 volts, single phase, 60 Hz electrical loads. These loads can require up to 6600 watts (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.

PRIMEPACT 66LP: 120 and/or 240 volts, single phase, 60 Hz electrical loads. These loads can require up to 6200 watts (6.2 kW) of power, but cannot exceed 51.7 AC amperes of current at 120 volts or exceed 25.8 AC amperes at 240 volts.

Do not overload the generator. Some installa- tions may require that electrical loads be alter- nated 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, multiply 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.

1.3INSTALLATION

This Owner’s Manual has been prepared under the assumption that a competent, qualified technician installed the generator into an industrial vehicle. We also assume the installer complied with all applicable codes, standards and regulations pertaining to instal- lation.

An INSTALLATION MANUAL was shipped with the generator. That Manual contains manufacturer’s instructions and recommendations for installing the unit into an industrial vehicle. After installation, installers should forward the Installation Manual to Owners/Operators for their information.

Owners/Operators have the responsibility to make sure that nothing is done that might render the instal- lation unsafe or in non-compliance with applicable codes, standards and instructions.

1.4SAFETY

Before using the generator set, carefully read GEN- ERAL SAFETY RULES inside the cover. Comply with these RULES to prevent accidents and damage to equipment and/or property. Generac suggests copy- ing and posting the GENERAL SAFETY RULES to potential operators of this equipment.

1.5GENERATOR AC CONNECTION

SYSTEM

These air-cooled generator sets are equipped with dual stator AC power windings. These two stator windings supply electrical power to customer electri- cal loads by means of a dual 2-wire connection sys- tem.

Generators may be installed to provide the following outputs:

1)120 VAC loads only — one load with a maximum total wattage requirement equal to the generator’s rated power output (in watts), and 120V across the generator output terminals. Figure 1.1, page 6, shows the generator lead wire connections for 120VAC ONLY.

2)120/240 VAC loads — one load with a maximum total wattage requirement equal to the generator’s rated power output, and 240V across the generator output terminals; or two seperate loads, each with a maximum total wattage requirement equal to half of the generator’s rated power output (in watts), and 120V across the generator output terminals. Figure 1.2, page 6, shows the generator lead wire connections for 120/240 VAC loads.
