WIRING CONNECTIONS

Fire hazard. Incorrect voltage can cause a
fire or seriously damage the motor and voids the warran-
ty. 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 compli-
ance with the United States 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:

Step 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.

Step 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.
Step 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.
Step 4. Connect the power supply wires to the pressure
switch as shown in Figure 6.
You have just completed the wiring for your
pump.
