1. CentriPro 2-Wire motors have Generation 1 and Generation 2 amp ratings, see motor nameplate or motor data sticker that was supplied with motor.
2. Amps are higher than controller overload range - use of these motors will limit current and provide reduced performance.

➀ Supply voltage must be 196 VAC –
265 VAC.
➁ Shaded areas indicate which controller
models can be used with which motors.
Lighter shading indicates combina-
tions where controller will limit peak
performance to 85% of catalog value for
pump/motor.
➂ Circuit Breaker or Dual Element Time De-
lay Fuse Size (Amps) protecting branch
circuit supplying controller.
➃ Minimum size of single phase 240 V
generator required.
