WIRING CONNECTIONS
WARNING
: Rick of electric shock. can shock, burn or kill.
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. 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.
Step 1. Install, ground, wire and maintain this pump in accordance with electrical code requirements. Consult your local
building inspector for information about codes.
Step 2. Provide a correctly fused disconnect switch for protection while working on motor. Consult local or national
electrical codes for switch requirements.
Step 3. Disconnect power before servicing motor or pump. If the disconnect switch is out of sight of pump, lock it open
and tag it to prevent unexpected power application.
Step 4. Ground the pump permanently using a wire of the same size as that specified in wiring chart, below. Make
ground connection to green grounding terminal under motor canopy marked GRD. Or
Step 5. Connect ground wire to a grounded lead in the service panel or to a metal underground water pipe or well casing
at least 10 feet long. Do not connect to plastic pipe or insulated fittings.
Step 6. Protect current carrying and grounding conductors from cuts, grease, heat, oil, and chemicals.
Step 7. Connect current carrying conductors to terminals L1 and L2 under motor canopy. When replacing motor, check
wiring diagram on motor nameplate against Figure 4. If the motor wiring diagram does not match Figure 4, follow
the diagram on the motor.
NOTICE: 115/230 Volt single phase models are shipped from factory with motor wired for 230 volts. If power supply is
115 volts, remove motor canopy and reconnect motor as shown in Figure 4. Do not try to run motor as received
on 115 volt current.
Step 8. Motor has automatic internal thermal overload protection. If motor has stopped for unknown reasons, thermal
overload may restart it unexpectedly, which could cause injury or property damage. Disconnect power before
servicing motor.
Step 9. If this procedure or the wiring diagrams are confusing, consult a licensed electrician.
