Heavy duty, 4-cycle, direct injection, diesel engine provides  
maximum reliability.  
Automatic start/stop control — automatically starts the  
generator set during a commercial power failure when used  
in conjunction with a transfer switch.  
Brushless alternator reduces service and maintenance  
requirements and meets temperature rise standards for Class  
H insulation systems.  
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.  
Open delta excitation design provides virtually unlimited  
excitation for maximum motor starting capability.  
Automatic voltage regulator (AVR) provides precise regulation.  
Automatic safety shutdown system monitors the water  
temperature, engine oil pressure, overspeed and overcrank.  
Warning lights indicate abnormal conditions.  
Electronic Governor Control (Crystal Sync) — maintains  
frequency to within 0.25% from no load to full load.  
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. The GFCI receptacles  
are NEMA 5-20, and the auxilillary outputs use CS6369 twist-  
lock receptacles.  
Full load acceptance of standby nameplate rating in one step  
(NFPA 110, para 5-13.2.6).  
Sound attenuated, weather resistant, steel housing provides  
operation at 60 dB(A) at 23 feet. Fully lockable enclosure  
allows safe unattended operation.  
Internal fuel tank with direct reading of fuel gauge.  
Simultaneous single and three phase power.  
Seven stage powder coat paint system provides durability  
and weather protection.  
Voltage selector switch offers the operator a wide range of  
voltages that are manually selectable. Fine tuning of the  
output voltage can be accomplished by adjusting the voltage  
regulator control knob to obtain the desired voltage.  
Fuel/water separator removes condensation from fuel for  
extended engine life. Panel mounted alarm light included.  
Complete engine analog instrumentation includes DC  
ammeter, oil pressure gauge, water temp. gauge, fuel level  
gauge, tachometer/hour meter, preheat indicator, emergency  
shutdown monitors.  
EPA emissions certified - Interim Tier 3 emissions compliant.

low noise Muffler — Large capacity low noise muffler  
minimizes exhaust sound.  
OPtiOnal cOntROl FEatUREs  
Emergency stop switch — when manually activated shuts  
down generator in the event of an emergency.  
soundproof casing The new design divides the cabinet into  
three sections, separating the engine, muffler and radiator for more  
efficient cooling and reduces noise from the engine and fans.  
audible alarm alerts operator of abnormal conditions.  
OPtiOnal gEnERatOR FEatUREs  
Electronic governor control (crystal sync) —  
maintains frequency to within 0.25% from no load to full load.  
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.  
Battery charger — provides fully automatic and self-  
adjusting charging to the generator's battery system.  
Jacket Water Heater — for easy starting in cold weather  
climates.  
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.  
special Batteries — long life batteries provide extra engine  
cranking power.  
spring isolaters — provides extra vibration protection for  
standby applications.  
low coolant level shutdown — provides protection  
from critically low coolant levels. Includes control panel  
warning light.  
trailer Mounted Package — meets National Highway  
Traffic Safety Administration (NHTSA) regulations. Trailer is  
equipped with electronic or surge brakes with tandem axle  
configuration.  
OPtiOnal OUtPUt cOnnEctiOns  
cam-lok connectors — provides quick disconnect  
alternative to bolt-on connectors.  
Pin and sleeve connectors — provides industry standard  
connectors for all voltage requirements.  
Output cable — available in any custom length and size  
configuration.
