Production tested and delivered to you in a package that is ready to be connected to your fuel and power lines. EPG designer computer sizing available. Supported 100% by your Caterpillar dealer with warranty on parts and labor; extended warranty available in some areas. The generator set was designed and manufactured in an ISO 9001 compliant facility. Generator set and components meet or exceed the following: AS1359, AS2789, BS4999, DIN6271, DIN6280, IEC 34/1, ISO3046/1, NEMA MG1-22. ■ DIESEL STRENGTH BUILT IN Blocks, crankshafts, liners, and connecting rods are common with Cat diesel engines. Gas engine pressures are 40%-50% lower, resulting in extra long life with the conomy of the gaseous fuel. ■ CATERPILLAR® SR4B GENERATOR Single bearing, wye connected, static regulated brushless excited generator designed to match the performance and output characteristics of the Caterpillar engine that drives it. ■ EXCLUSIVE CATERPILLAR VOLTAGE REGULATOR Three-phase sensing and Volts per Hertz regulation with constant voltage in the normal operating range gives precise control and excellent load acceptance.

RATING DEFINITIONS AND CONDITIONS Ratings are based on SAE J1349 standard conditions of 29.61 in Hg (100 kPa) and 77° F (25° C). These ratings also apply at ISO3046/1, DIN6271, and BS5514 standard conditions of 29.61 in Hg (100 kPa) and 81° F (27° C); and API 7B-11C standard conditions of 29.38 in Hg (99 kPa) and 85° F (29° C) also apply. Naturally aspirated engines apply to 500 ft (150 m) and 77° F (25° C). For applications which exceed these limits consult your Caterpillar dealer. Ratings are based on dry natural gas having a low heat value of 905 btu/ft3 (35.22 MJ/m3 ). Variations in altitude, temperature, and gas composition from standard conditions may require a reduction in engine horsepower; consult your Caterpiller dealer. Materials and specifications are subject to change without notice. LEHX7575 Standby — Output available with varying load for the duration of the interruption of the normal source power. Fuel stop power in accordance with ISO3046/1, AS2789, DIN6271, and BS5514. The International System of Units (SI) is used in this publication. © 1997 Caterpillar Inc. Printed in U.S.A.
