Generac 005411-0 User Manual

These Installation Instructions have been prepared especially for 

the purpose of familiarizing installers and owners of the applicable 

equipment with the product's installation requirements. Give seri-

ous consideration to all information and instructions in the manual, 

both for safety and for continued reliable operation of the equip-

ment.
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 for every possible 

installation. 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 applicable 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, 

standards or regulations must take precedence over the manual.

Before handling, installing, operating or servicing this equipment, 

carefully read the “Notice to Installer” and “Safety Rules”. Comply 

with all safety rules to prevent death, personal injury or damage to 

equipment and/or property. Stress safety to all installers, operators 

and service technicians who work on this equipment.

Installation, use and servicing of this equipment should comply 

strictly with published standards, as well as the manufacturer's 

recommendations. The following standards booklets (latest revi-

sion) are available from the sources indicated:

Instructions and information in this section pertain to air-cooled 

generators. These generators are designed specifically for install-

ing in recreational vehicles. They operate 120-volt, single-phase, 

60-Hertz, AC electrical loads.

The generator’s revolving field (rotor) is driven by a two-cylinder, 

four-cycle engine through a pulley and drive belt arrangement. The 

generator supplies 120 volts AC at 60 Hertz when the rotor is oper-

ating at 3,600 rpm. The drive belt arrangement allows the engine to 

operate at a lower speed than the rotor.

These air-cooled generator sets are 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 connection 

system. 
Generators may be installed to provide the following outputs:
1. 120 VAC loads only — two 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 out-

put terminals (see Fig. 1.1).

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 separate 

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 (see Fig. 1.3).
