Air flow restriction (system) is added to existing restriction fromfactory.2 UL 2200 Listed packages may have oversized generators with a different temperature rise and motor starting characteristics. Generatortemperature rise is based on a 40 degree C ambient per NEMA MG1-32.3 Emissions data measurement procedures are consistent with those described in EPA CFR 40 Part 89, Subpart D & E and ISO8178-1 formeasuring HC, CO, PM, NOx. Data shown is based on steady state operating conditions of 77ºF, 28.42 in HG and number 2 diesel fuelwith 35º API and LHV of 18,390 btu/lb. The nominal emissions data shown is subject to instrumentation, measurement, facility and engineto engine variations. Emissions data is based on 100% load and thus cannot be used to compare to EPA regulations which use valuesbased on a weighted cycle.

RATING DEFINITIONS AND CONDITIONS

Meets or Exceeds International Specifications: AS1359,CSA, IEC60034-1, ISO3046, ISO8528, NEMA MG 1-22,NEMA MG 1-33, UL508A, 72/23/EEC, 98/37/EC,2004/108/ECPrime - Output available with varying load for anunlimited time. Average power output is 70% of theprime power rating. Typical peak demand is 100% ofprime rated ekW with 10% overload capability foremergency use for a maximum of 1 hour in 12. Overloadoperation cannot exceed 25 hours per year. Prime powerin accordance with ISO3046. Prime ambients shownindicate ambient temperature at 100% load which resultsin a coolant top tank temperature just below the alarmtemperature.

Ratings are based on SAE J1349 standard conditions.These ratings also apply at ISO3046 standard conditions.Fuel rates are based on fuel oil of 35º API [16º C (60º F)]gravity having an LHV of 42 780 kJ/kg (18,390 Btu/lb)when used at 29º C (85º F) and weighing 838.9 g/liter(7.001 lbs/U.S. gal.). Additional ratings may be availablefor specific customer requirements, contact yourCaterpillar representative for details. For informationregarding Low Sulfur fuel and Biodiesel capability,please consult your Caterpillar dealer.
