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 themotor.
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.
Figure 1 - Single phase, 2-wire connections. This
is correct connection information for 115 and
230 volt 2-wire motors only.

Installation must meet United States National
Electrical Code, Canadian Electrical Code,
and local codes for all wiring (as applicable).
If main overload trips, look for:
1. Shorted capacitor
2. Voltage problems
3. Overloaded or locked pump.
