WIRING
1. Install, ground, wire and maintain this
pump in accordance with your local
electrical code and all other codes
and ordinances that apply. Consult
your local building inspector for local
code information.
2. Ground the pump permanently using
a wire of size and type specified
by local or United States National
Electrical Code. Do not ground to a
gas supply line.
3. Connect ground wire first. Connect
to ground first, then to green
grounding terminal provided on the
motor frame, identified as GRD.
Ground connection MUST be made
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.
4. Connect the other end of the ground
wire to a properly grounded service
panel or to a control panel ground
bar if it is connected to the power
supply ground.
IMPORTANT:
Check local and/or United
States National Electric Codes for proper
grounding information.
Make certain that
the power supply
conforms to the electrical specifications of
the motor supplied. See Motor Data
Charts.
