DEFINITIONS AND CONDITIONS
1. For ambient and altitude capabilities consult your Cat dealer. Air flow restriction (system) is added to existing
restriction from factory.
2. UL 2200 Listed packages may have oversized generators with a different temperature rise and motor starting
characteristics. Generator temperature rise is based on a 40° 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 for measuring HC, CO, PM, NOx. Data shown is based on steady state operating conditions of
77° F, 28.42 in HG and number 2 diesel fuel with 35° API and LHV of 18,390 btu/lb. The nominal emissions data
shown is subject to instrumentation, measurement, facility and engine to engine variations. Emissions data is based
on 100% load and thus cannot be used to compare to EPA regulations which use values based on a weighted cycle.
