1
Turn off the AC power from the main power source circuit breaker.
2
Run the AC power wires to the control box.
3
Remove the junction box cover.
4
Connect the green wire to the earth ground rod wire using a wire nut.
5
Connect the white wire to NEUTRAL using a wire nut.
6
Connect the black wire to HOT using a wire nut.
7
Replace the junction box cover. Ensure the wires are not pinched.
NOTE:
The operator can also be wired for 240 Vac application. Refer to the
Accessory page for more information.
NOTE:
Use copper conductors ONLY.
