standards or regulations, the applicable codes, stan­
dards or regulations must take precedence over the

EQUIPMENT DESCRIPTION
Instructions and information in this section pertain to
Generac Impact air-cooled generators — more specifi­
cally, the installation of Impact-34 plus and Impact-36
plus recreational vehicle generators. These generators
are designed specifically for installing in recreational
vehicles.
ENGINE GENERATOR
OPERATING SPEED
The generators are driven by gasoline-powered, sin­
gle-cylinder engines. The engines drive revolving fields
(rotors), high frequency, permanent magnet alterna­
tors. The generators supply 120 volts AC at 60 Hertz
with DC inverter. The generators revolving fields are
driven at a variable speed depending on the demand
for power. Computers monitor that demand and adjust
the engine speed to provide adequate power to the
connected loads.
