Electrical supply MUST match pump's name-
plate specification. Incorrect voltage can cause
fire or damage to the motor and voids war-
ranty.
Motors without built-in protection MUST be
provided with contactors and thermal over-
loads for single phase motors, or starters with
heaters for three phase motors. See motor
nameplate.
•
Follow motor manufacturer's wiring diagram on the
motor nameplate or terminal cover carefully.
•
Use only copper wire to motor and ground. The
ground wire MUST be at least as large as the wire to
the motor. Wires should be color coded for ease of

maintenance.
