Installation Wiring Diagrams
Risk of electric shock. Can shock,
burn or kill. Ground control box, all metal
plumbing, and motor frame with copper wire in
compliance with local codes. Use a ground wire
at least as large in gauge as the wires supplying
power to the motor.
Single Phase, 2 Wire
2-wire pumps have two power supply wires
(Black/Black) and one ground wire (Green).
Control box is not required. See Figure 1 for
correct hook-up information for 2-Wire motors.

Single Phase, 3 Wire
Permanently close all unused openings in this
and other equipment enclosures.
Disconnect power to control box before working
on or around control box, pipes, cable, pump,
or motor.
To be sure that starting relay will function and
that overload will not "nuisance trip", install
control box vertically with top side up.
Wire control box as shown in Figure 2 . A 3-wire
pump will not operate without a control box
and will burn out a 3-wire motor.
230V Line

color coding when connecting control box
(Yellow to Y, Red to R, Black to B).
