ELECTRICAL
motor (3 load conductors plus a ground wire), and three
wires when looking at a “2-Wire” motor (2 load conductors
plus a ground wire). “3-Wire” motors require an electrical
disconnect switch plus a Control Center; “2-Wire” motors
use only an electrical disconnect switch.
WIRING
Hazardous voltage. Can shock burn, or
cause death. Install pump with all electrical wiring
and grounding in accordance with your local electri-
cal code.
Install and use pump only in a well application.
Disconnect power before installing pump, pressure switch,
and control center.
Make sure power is off before wiring control center. Follow
wiring diagram, Figures 4 and 5.
Make sure that the line voltage and frequency stamped on
the motor nameplate agree with the voltage and frequency
of the electrical power supply. If in doubt, check with your
electric power company or a licensed electrician.
Check Fusing and Wiring Chart before connecting wires
from pressure switch to electric power. All wiring must
comply with your local electrical code.
See Chart, Page 3.
