Motor is supplied with a copper ground wire.
Splice this ground wire to a copper conductor that
matches motor wire size specified in Table III. See
Page 5 for wire splicing instructions.
Permanently ground pump, motor and control box
before connecting power cable to power supply.
Connect ground wire to approved ground first and
then connect to equipment being installed.
Do not ground to a gas supply line.
Fire and electrical shock hazard. If
using a drop wire larger than No. 10 (5.5mm
2
)
(for example, No. 8 (8.4mm
2
) wire) between
pump and control box, run wire to a separate
junction box. Connect junction box to control box
with a No. 10 (5.5mm
2
) or smaller wire (depend-
ing on amp rating of pump – see Table III).
For more information, contact your local code
officials.
WIRING CONNECTIONS:
All wiring must meet National Electrical Code or
Canadian Electrical Code and local code require-
ments.
Use only copper wire when making connections to
pump and control box.
To avoid over-heating wire and excessive voltage
drop at motor, be sure that wire size is at least as
large as size listed in Table III for your horsepower
pump and length of wire run.
NOTICE: When built-in overheating protection is
not provided, use with an approved overload
equipped motor control that matches motor input in
full load amps. Select or adjust overload element(s)
in accordance with control instructions. When
built-in overheating protection is provided, use with
an approved motor control that matches motor
input in full load amperes.

Hazardous voltage. Can shock,
burn, or kill.
Ground control box, all metal plumbing, and motor
frame with copper wire in compliance with local
codes. Use a ground wire at least as large as the
wires supplying power to motor.
Permanently close all unused openings in this and
other equipment.
Disconnect power to control box before working on
or around control box, pipes, cable, pump, or
motor.

All cable lengths meet NEC for jacketed 60°C copper cable. Based on 3-Wire Induction Run requirements; Capacitor Run requirements may vary. Local
code requirements may vary. For aluminum cable, go up two sizes from chart (for example, if the chart calls for No. 10 AWG (6mm
2
) for copper, go to
No. 8 AWG (10mm
2
) for aluminum; the smaller the number, the larger the cable). Use oxidation inhibitors on the connections.
