ELECTRICAL (Continued)
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.
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 @.
5. Connect ground wire to a grounded lead in the service
panel or to a metal underground water pipe or well caS-
ing at least 10 feet long. Do not connect to plastic pipe or
insulated fittings.
6. Protect current carrying and grounding conductors from
cuts, grease, heat, oil, and chemicals.
7. Connect current carrying conductors to terminals L1 and
L2 under motor canopy. When replacing motor, check
wiring diagram on motor nameplate against Figure6. Ifthe
motor wiring diagram does not match the diagrams in
Figure 6, 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 re-
connect motor as shown in Figure 6. Do not try to run motor
as received on 115 volt current.
8. Motor has automatic internal thermal overload protec-
tion. If motor has stopped for unknown reasons, thermal
overload may restart it unexpectedly, which could cause
injury or property damage. Disconnect power before ser-
vicing motor.
9. If this procedure or the wiring diagrams are confusing,
consult a licensed electrician.
