■ Heavyduty, 4-cycle, direct injection, turbo charged, charge air cooled diesel engine provides
maximum reliability.
■ Brushless alternator reduces service and maintenance requirements and meets temperature rise
standards for Class H insulation systems.
• Open delta excitation design provides virtually unlimited excitation for maximum motor starting
• Automatic voltage regulator (AVR) provides precise regulation.
■ Electronic Governor Control —isochronous control, maintains frequency to within ±0.25% from no load
to full load.
■ Full load acceptance of stand byname plate rating in one step (NFPA 110, para 5-13.2.6).
■ Sound attenuated, weather resistant, steel housing provides operation at 66 dB(A) at 23 feet.
Fully lockable enclosure allows safe unattended operation.
■ Internal fuel tank with direct reading of fuel gauge.
■ E-coat and powder coat paint provides durability and weather protection.
■ Fuel/water separator removes condensation from fuel for extended engine life. Panel mounted
alarmlight included.

gauge, fuel level gauge, tachometer/hour meter, preheat indicator, and emergency shutdown monitors.

failure when used in conjunction with a transfer switch.
■ Completeg enerator analogi nstrumentationi ncludes voltage regulator control, ammeter phase selector
switch, voltmeter phase selector switch, ACvoltmeter, ACammeter, 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.
■ 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 NEMA5-20, and the auxiliary outputs use CS6369 twist-
lock receptacles.
■ 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.
■ EPA emissions certified —Tier 4 final emissions compliant.
■ Spill containment —Bundedd esignp rotects environment by capturing up to 119%of engine fluids.
