Wiring Connections
Fire hazard.
Incorrect voltage can cause a fire
or seriously damage the motor and voids the warranty. The
supply voltage must be within ±10% of the motor nameplate
voltage.
NOTICE:
Dual-voltage motors are factory wired for 230 volts.
If necessary, reconnect the motor for 115 volts, as shown. Do
not alter the wiring in single voltage motors.
Install, ground, wire, and maintain your pump in compliance
with the National Electrical Code (NEC) or the Canadian
Electrical Code (CEC), as applicable, and with all local codes
and ordinances that apply. Consult your local building inspec-
tor for code information.
Connection Procedure:
1. Connect the ground wire first as shown in Figure 6. The
ground wire must be a solid copper wire at least as large
as the power supply wires.
2. There must be a solid metal connection between the pres-
sure switch and the motor for motor grounding protection.
If the pressure switch is not connected to the motor, con-
nect the green ground screw in the switch to the green
ground screw under the motor end cover. Use a solid cop-
per wire at least as large as the power supply wires.
3. Connect the ground wire to a grounded lead in a service
panel, to a metal underground water pipe, to a metal well
casing at least ten feet (3M) long, or to a ground electrode
provided by the power company or the hydro authority.
4. Connect the power supply wires to the pressure switch as
shown in Figure 6.
