7-Addendum 2 RFP 3809 Variable Frequency Drive (VFD) over 100HP Attachment C.pdf

This document is Addendum #2 - Attachment C for RFP 3809, a Variable Frequency Drive (VFD) project issued by Eastern Municipal Water District (EMWD) for facilities located in Moreno Valley and Perris Valley, California. The addendum includes motor nameplate documentation for specific pumps and equipment at two regional water reclamation facilities: Moreno Valley Regional Water Reclamation Facility (MVRWRF) and Perris Valley Regional Water Reclamation Facility (PVRWRF). The motor nameplates provide technical specifications for motors associated with TEPS 4, IPS 1, IPS 3, Utility Water Pump 4, and IPS Pump, all of which are over 100 HP and designated for inverter duty.

The motor nameplates reveal detailed technical specifications including manufacturer information from NIDEC Motor Corporation, Emerson Motor Company, ABS, and Baldor-Reliance. The documentation includes critical operational details such as voltage (460V), RPM (typically around 1785), horsepower, amperage, temperature ratings, efficiency codes, and specific configuration parameters for variable frequency drive compatibility. These technical specifications are essential for potential bidders to understand the exact motor characteristics and ensure proper replacement or retrofitting of variable frequency drives for the water reclamation facility equipment.
