WIRING CONNECTIONS
1. Install, ground, wire and maintain this pump in com-
pliance 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.
2. Make sure that the voltage, frequency and phase (sin-
gle phase or three phase) of the power supply agree
with that stamped on the motor nameplate. If in
doubt, check with the power company.
3. 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.
NOTICE:
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 (See Page 5). Do not alter the wiring in single
voltage motors.
Install, ground, wire, and maintain your pump in com-
liance with the National Electrical Code (NEC) or the
Canadian Electrical Code (CEC), as applicable, and with
all local codes and ordinances that apply. Consult your
local building inspector for code information.
NOTICE
: Clamp the power cable to prevent strain on the
terminal screws.
NOTICE: Do not change motor wiring if line voltage is
230 volts. Connect power supply as shown for your sup-
ply voltage.
NOTICE:
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
Risk of electrical shock.
1. Be sure power is disconnected to motor when work-
ing 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.
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
con-
nect motor to electrical power supply until unit is per-
manently grounded; otherwise serious or fatal electri-
cal 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 elec-
trode furnished by the power company.
