ELECTRICAL
Figure 10 – 115/230 volt motor wiring
connections.
Dual voltage motors come factory wired for 230 volt
operation. Inset shows 115 Volt conversion.
Do not alter wiring on single voltage motors.
Match motor voltage to power supply voltage.
Risk of serious or fatal
electrical shock.
Connect motor ground wire
before connecting power
supply wires.
Do not ground to a gas sup-
ply line.
Turn off power before work-
ing on pump or motor.
Match motor voltage and power supply voltage.
Supply
voltage must be within ±10% of motor nameplate voltage.
Incorrect voltage can cause fire or seriously damage motor
and voids warranty. If in doubt, consult a licensed electri-
cian.
Use wire size specified in wiring chart.
If possible, con-
nect pump to a separate branch circuit with no other appli-
ances on it.
1. Install, ground, wire and maintain pump in accordance
with your local electrical code and all other codes/ordi-
nances that apply. Consult your local building inspector
for code information.
2. Connect ground wire first as shown at left. Ground wire
must be a solid copper wire at least as large as power sup-
ply wires.
• Connect ground wire to grounded lead in service panel,
metal underground water pipe, well casing at least 10’
(3M) long, or to ground electrode provided by power
company.
3. Connect power supply wires as shown at left.
