Electrical supply
MUST
match pump’s
nameplate specification. Incorrect voltage can
cause fire or damage to the motor and voids
warranty.
Motors without built-in protection
MUST
be
provided with contactors and thermal overloads
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.
