WIRING CONNECTIONS
,AWARNING] 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 name-
plate 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 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:

230 Volt: Connect 2 hot wires(black andred)
here andcap the white(neutral) wire. It does

115 Volt: Connect onehot wire (black or red)
to one of these screws (it'doesn'tmatter

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 protec-
tion. 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.

5.
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.
Connect the power supply wires to the pressure switch
as shown in Figure 6.
Reinstall the pressure switch cover.
