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 may be set for 115V or 230V. If necessary,

reset the motor to the desired voltage, 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 inspector for code information.

Connection Procedure:

1. Connect the ground wire first as shown in Figure 14. 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 pressure switch

and the motor for motor grounding protection. If the pressure switch

is not connected to the motor, connect the green ground screw in the

switch to the green ground screw under the motor end cover. Use a

solid copper 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

(3m) 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14.

You have just completed the wiring for your pump.
