Standard Features:

Heavy duty, 4-cycle, direct injection, turbocharged, air
to air intercooled diesel engine provides maximum
reliability.
Brushless alternator reduces service and maintenance
requirements and meets temperature rise standards for
Class F insulation systems.
Open delta alternator design provides virtually unlimited
excitation for maximum motor starting capability.
Automatic voltage regulator (AVR) provides precise
regulation.
Electronic governor system maintains frequency to
±0.25%.
Full load acceptance of standby nameplate rating in one
step (NFPA 110, para 5-13.2.6).
Internal fuel tank with direct reading fuel gauges are
standard.
Fuel/water separator removes condensation from fuel for
extended engine life.
Heavy duty, 2 stage air filter assembly
Panel mounted, engine idle speed switch
Divided panel enclosure provides separation of DC and
AC components.
Internal mounted document box — inside of the housing
for easy document storage and access.
Complete engine analog instrumentation includes DC
ammeter, oil pressure gauge, water temp. gauge, fuel level
gauge, tachometer/hour meter, manual engine speed
control, and emergency shutdown monitors.
Complete generator analog instrumentation includes
voltage regulator control, ammeter phase selector switch,
voltmeter phase selector switch, AC voltmeter, AC ammeter,
frequency meter, panel light, and circuit breaker.
Automatic safety shutdown system monitors the water
temperature, engine oil pressure, overspeed, and overcrank.
Warning lights indicate abnormal conditions.
Auto start/stop control allows generator to start
automatically in the event of a commercial power failure.
Complete power panel. Fully covered; three-phase
terminals and single phase receptacles allow fast and
convenient hookup for most applications including temporary
power boxes, tools and lighting equipment. All are NEMA
standard.
Sound attenuated, weather resistant, steel housing
provides operation at 63 dB(A) at 23 feet. Fully lockable
enclosure allows safe unattended operation.
Seven stage powder coat paint provides durability and
weather protection.
EPA emissions certified - Tier 3 emissions compliant.

Optional Generator Features:

Battery Charger — provides fully automatic and selfadjusting
charging to the generator's battery system.
Jacket Water Heater — for easy starting in cold weather
climates.
Special Batteries — long life batteries provide extra engine
cranking power.
Spring Isolaters — provides extra vibration protection for
standby applications.
Trailer Mounted Package — meets National Highway
Traffic Safety Administration (NHTSA) regulations. Trailer is
equipped with electronic or surge brakes with double or triple
axle confi guration.

Optional Control Features:

Emergency Stop Switch.
Audible Alarm — alerts operator of abnormal conditions.
Low coolant level shutdown system provides
protection from critically low coolant levels. Includes
control panel warning light.

Ultra-Silent Features:

Low Noise Muffler — Large capacity low noise muffl er
minimizes exhaust sound.
Soundproof Casing — The new design divides the cabinet into
three sections, separating the engine, muffl er and radiator for more
effi cient cooling and reduces noise from the engine and fans.
New Cooling System — An advanced design uses two
separate air intake systems to cool the generator. The engine
fan draws air in to cool the engine and generator housing while
a second electric fan directly cools the radiator. With less air
being drawn into the generator through each fan, considerably
less noise is produced through the top of the generator.
Environmental Design — Constructed using an integrated
environmental skid and fuel tank. This design fully contains fuel
leakage and any liquid that might leak from the engine such as
lube oil or radiator coolant. All potentially hazardous liquids are
contained without contaminating the surrounding area.
