Wiring
Risk 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 (below). 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 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
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.
