WIRING CONNECTIONS
Ground motor before connecting to electrical
power supply. Failure to ground motor can cause severe or fatal
electrical shock hazard.
EXPLOSION HAZARD. Do not ground to a gas
supply line.
To avoid dangerous or fatal electrical shock, turn
power OFF to motor before working on electrical connections.
Supply voltage must be within ±10% of nameplate voltage.
Incorrect voltage can cause fire or serious damage to motor and
voids warranty. If in doubt consult a licensed electrician.
For All 3-phase and TEFC Motors: Follow the wiring diagram
on the motor junction box or on the motor nameplate.
Use wire size specified in this manual's 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.
Dual voltage motors without cords are factory wired for 230
volts. If necessary, reconnect the motor for 115 volts, as
shown. All cord connected motors are wired for 115 volts. Do
not alter the wiring in single voltage motors.
Install, ground, wire and maintain this pump in compliance
with the National Electrical Code (NEC) or the Canadian
Electrical Code (CEC) and with all local codes and
ordinances that apply. Consult your local building inspector
for local information.
Make sure that the voltage, frequency and phase (single
phase or three phase) of the power supply agree with that
stamped on the motor nameplate. If in doubt, check with
the power company.
Some models are equipped with three phase motors. Three
phase motors require magnetic starters and can run in
either direction, depending on how they are connected to
the power supply.
TO CHECK FOR PROPER ROTATION – 3 PHASE MOTORS
1.
Be sure power is disconnected to motor when working on
electrical connections.
2.
Remove the motor end cover, exposing motor shaft.
Momentarily start pump. If hookup is correct, the shaft will
rotate clockwise.
3.
If rotation is not clockwise, reverse any two leads to the
starter. The rotation will now be correct.

GROUNDING THE MOTOR
Ground the pump permanently using a wire of size and type
specified by local or National Electrical Code.
Models (HP7C and HP7D Series Only) with factory installed cord
and plug:
This equipment is only for use on 115V and is equipped with an
approved 3-conductor cord and 3-prong, grounding type plug. To
reduce the risk of electric shock, be certain that it is connected
to a properly grounded, grounding type receptacle. Do not
modify or remove plug. Make sure pump circuit meets National
Electrical Code. To avoid dangerous electrical shock hazard,
keep cord dry at
all times.
Models without cord and plug:
1.
Connect ground wire first. Connect the ground first, then to
green grounding terminal provided under motor canopy (see
Figures 6 and 7) identified as GRD. Make ground connection
to this terminal. Do not connect motor to electrical power
supply until unit is permanently grounded; otherwise
serious or fatal electrical shock hazard may be caused.
2.
For best ground connection, connect to a grounded lead in
the service panel or to a metal underground water pipe or
well casing at least 10 ft. long. If plastic pipe or insulated
fittings are used, run ground wire directly to the metal well
casing or use ground electrode furnished by the power
company.
