Definitions and Conditions
Note (01)Fuel Rates :Fuel consumption reported in accordance with ISO 3046-1, based on fuel oil of 35 °API [16 °C (60 °F)] gravity having an LHV of 42,780 kJ/kg (18,390 Btu/lb) when used at 15 °C (59 °F) and weighing 850 g/liter (7.0936 lbs/U.S. gal.) All fuel consumption values refer to rated engine power.
Standards and CodesAS 1359, ULC 2200 3rd edition, UL 489, UL 869A, IBC, IEC 60034-1, ISO 3046, ISO 8528, NEMA MG1-22, NEMA MG1-33, 2014/35/EU, 2006/42/EC, 2014/30/EU and facilitates compliance to NFPA 37, NFPA 70, NFPA 99, NFPA 110. Note: Codes may not be available in all model configurations. Please consult your local Cat dealer for availability. Data Center Applications: • All ratings Tier III/Tier IV compliant per Uptime Institute requirements. • All ratings ANSI/TIA-942 compliant for Rated-1 through Rated-4 data centers.
Mission CriticalOutput available with varying load for the duration of the interruption of the normal source power. Average power output is 85% of the mission critical rated ekW. Typical peak demand up to 100% of rated power for up to 5% of the operating time. Typical operation is 200 hours per year, with maximum expected usage of 500 hours per year.
PrimeOutput available with varying load for an unlimited time. Average power output is 70% of the prime power rating. Typical peak demand is 100% of prime rated ekW with 10% overload capability for emergency use for a maximum of 1 hour in 12. Overload operation cannot exceed 25 hours per year.
StandbyOutput available with varying load for the duration of the interruption of the normal source power. Average power output is 70% of the standby rated ekW. Typical operation is 200 hours per year, with maximum expected usage of 500 hours per year.
