Wiring Connections
1. Install, ground, wire and maintain this pump in
compliance with the National Electrical Code (NEC)
or the Canadian Electrical Code (CEC) and with all
local codes and ordinances that apply. Consult your
local building inspector for local code information.
2. Make sure that the voltage, frequency and phase
(single phase) of the power supply agree with that
stamped on the motor nameplate. If in doubt, check
with the power company.
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
comliance 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 local code information.
NOTICE Clamp the power cable to prevent strain on the
terminal screws.
NOTICE Voltage setting (under the motor end cover)
options are shown in Figure 6 and 7. Do not change
motor wiring if line voltage is 230 volts. Connect power
supply as shown for your supply voltage.
Grounding the Motor
Ground the pump permanently using a wire of size and
type specified by local or National Electrical Code.
1. Connect ground wire first. Connect the ground first,
then to green grounding terminal provided under
motor canopy (see Figure 6) identified as GRD.
Make ground connection to this terminal. Do not
connect motor to electrical power supply until unit
ispermanentlygrounded;otherwiseseriousorfatal
electrical shock hazard may be caused.
2. For best ground connection, connect to a grounded
lead in the service panel or to a metal underground
water pipe or well casing at least 10 ft. long. If
plastic pipe or insulated fittings are used, run ground
wire directly to the metal well casing or use ground
electrode furnished by the power company.
