Connection diagram for dual voltage, single-phase
motors. Your dual-voltage motor's terminal board (under
the motor end cover) will match one of the diagrams
below. Follow that diagram if necessary to convert motor
to 115 Volt power.
Connect power supply wires to L1 and L2. For 3-phase
motors, or if motor does not match these pictures, follow
the connection diagram on the motor nameplate.
MOTOR SWITCH SETTINGS
Dual-voltage motors (motors that can operate at either
115 or 230 volts), are set at the factory to 230 volts. Do
not change motor voltage setting if line voltage is 230
volts, or if you have a single voltage motor.
NOTE: Never wire a 115 volt motor to a 230 volt line.
REMOVE MOTOR END COVER
If you have a dual-voltage motor, and will connect it to
115 volts, follow the procedure below.

Figure 6: Removing Motor End Cover
You will need to remove the motor end cover to change
the voltage setting.
Your motor terminal board (located under the motor end
cover) should look like one of those below.

To change to 115 volts:
1. Make sure power is off.
2. Pull the plug straight up.
3. Move and attach the plug at the 115 volt position.
The plug will now cover 2 metal tabs. The arrow on
the plug will point to 115V.
4. Attach the power lead wires to the power lead
terminals. Make sure the wires are secure.

To change to 115 volts:
1. Make sure power is off.
2. Turn the dial counter-clockwise until 115 shows in
the dial window.
3. Attach the power lead wires to the power lead
terminals. Make sure the wires are secure.
4. Attach the ground wire to the green ground screw
5. Reinstall the Motor end cover

Hazardous voltage. Can shock, burn,
or cause death. Disconnect power to motor before
working on pump or motor. Ground motor before
connecting to power supply.
For All 3­phase Motors: Follow the wiring diagram on
the motor junction box or on the motor nameplate. For
575 volt installations, consult a licensed electrician.

WIRING CONNECTIONS

Ground motor before connecting to electrical
power supply. Failure to ground motor can cause
severe or fatal electrical shock hazard.
Do not ground to a gas supply line.
To avoid dangerous or fatal electrical shock, turn
OFF power to motor before working on electrical
connections.
Supply voltage must be within ±10% of nameplate
voltage. Incorrect voltage can cause fire or damage
motor and voids warranty. If in doubt consult a licensed
electrician.
Use wire size specified in Wiring Chart, Page 7. If
possible, connect pump to a separate branch circuit
with no other appliances on it.
Wire motor according to diagram on motor
nameplate. If nameplate diagram differs from
diagrams above, follow nameplate diagram.
