Replacement Considerations: Commercial information describes a replacement motor based on the original unit. This does not establish direct interchangeability with another GNA132 variant. The original nameplate, mechanical drawing, electrical characteristics and DC drive configuration must be checked.

Safety Notice: DC motors with separate or shunt field excitation can be subject to dangerous overspeed conditions following field loss. Appropriate field monitoring, drive protection and qualified servicing procedures are required.
