WIRING
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 dam-
age 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 cir-
cuit with no other appliances on it.
Wire motor according to diagram on motor name- plate. 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 informa- tion about codes.
Step 2. Provide a correctly fused disconnect switch for pro- tection 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 unex- pected 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 ground- ing 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 conduc- tors 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 the diagram, follow the diagram on the motor.
IMPORTANT: 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 change switch dial on 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 unex- pectedly, which could cause injury or property damage. Disconnect power before servicing motor.
Step 9. If this procedure or the wiring diagrams are con- fusing, consult a licensed electrician.
