NOTE:
1. Maximum wire lengths shown maintain motor voltage at 95% of
service entrance voltage, running at maximum nameplate amperes.
If service entrance voltage will be at least motor nameplate voltage
under normal load conditions, 50% additional length is permissable
for all sizes.
2. Sizes given are for copper wire. For aluminum wire go two sizes
larger (i.e., if table lists #12 (3mm
aluminum wire.)
INSTALLATION WIRING INSTRUCTIONS
Single Phase, 3 Wire
Hazardous voltage. Can shock, burn, or kill.
Ground control box, all metal plumbing, and motor frame
with copper wire in compliance with Canadian Electrical Code or National
Electrical Code and local codes. Use ground wire at least as large as the
wires supplying power to motor.
At well head, connect ground wire to grounding terminal that meets
Canadian Electrical Code or National Electrical Code requirements that
apply. For more information, contact local code officials.
Permanently close all unused openings in this and other equipment.
Disconnect power before working on or around control box, pipes, cable,
pump, or motor.
NOTICE: Install control box vertically on wall with top side up.
3-Wire pumps have three power supply wires (Red/Black/Yellow) and one
ground wire (Green).
Attempting to operate 3 wire pump without a control box will burn out the
motor.
Installations must include circuit and component protection in
compliance with U.S. National Electrical Code or Canadian Electrical
Code, Part 1.
If main overload trips, look for:
1. Shorted Capacitor
2. Voltage Problems
3. Overload or locked pump.
NOTICE: Use only control box specified for your 3-wire pump. Make sure
motor and control box match (Table 4). FAILURE TO DO SO WILL VOID
WARRANTY.

2-Wire pumps have two power supply wires (Black) and one ground
wire (Green). DO NOT USE a control box with a 2-wire motor.
See Figure 1B for correct hook-up information for 115 or 230 Volt
2-Wire motors only.
