Introduction
Note: Caterpillarretail gaseous fueled 175-450 KW generator sets are manufactured with dedicated output voltage, current, KW and frequency ratings, as shipped from the factory. The choice to perform a voltage change over on these generator sets is strictly a business decision for a dealership.Note: The voltage change over process is not supported by Caterpillar Engineering, Caterpillar Dealer Solution Network (DSN), Caterpillar Application and Installation (A&I) or the Caterpillar Customer Service Support.This document provides limited reference information to assist the dealer to implement a voltage change over for these Caterpillar retail gaseous fueled generator sets.There are no technical documents available from Caterpillar Engineering, Caterpillar Dealer Solution Network (DSN), Caterpillar Application and Installation (A&I) or the Caterpillar Customer Service Support to perform a voltage change over. The dealer should use existing published Schematics, Technical Information Bulletins (TIB) and other manuals as provided on Caterpillar Power Net Website, Service Information System (SIS) and Technical Marketing Information (TMI) to create their own process, disassembly and assembly instructions.Precaution
Only 12 lead model alternators are capable of being re-strapped.
Alternator de-rates should be considered when re-strapping the output voltage of an alternator.
The Caterpillar dealership are responsible for action items associated with, the pursuit and implementation of a generator set voltage change over.
The Caterpillar dealership is responsible for determining if there are any necessary iron changes required and identifying the associated service part numbers for any iron changes required, through the dealership parts department, price list, Service Information System (SIS) and Technical Marketing Information (TMI).
The Caterpillar dealership is responsible for determining the necessary alternator re-configuration wiring needed for their specific application and to ensure that the alternator re-configuration is correct and accurately implemented.
The Caterpillar dealership is responsible for all costs and liability associated with re-configuring the alternator.Alternator Wiring Configurations
