POWER WIRING
1. Turn off the AC power from the main power source circuit breaker.
2. Run the AC power wires to the operator.
3. Unplug the transformer.
4. Remove the junction box cover.
5. Run the AC power wires through the knockout in the bottom of the
electrical box.
6. Connect the green wire to the earth ground rod and AC ground using
a wire nut. NOTE: The earth ground rod can be grounded to the
chassis.
7. Connect the white wire to NEUTRAL using a wire nut.
8. Connect the black wire to HOT using a wire nut.
9. Replace the junction box cover. Ensure the wires are not pinched.
10. Plug in the transformer.
11. Turn ON AC power to the operator.
To use a 33AH battery in place of the 7AH battery, follow the
instructions below. The 33AH application requires the 33AH wire
harness (Model K94-37236).
33AH BATTERY
1. Unplug the transformer.
2. Unplug the J15 plug labeled BATT on the control board by squeezing
the plug and pulling it from the control board. This disconnects the
ac/dc power to the control board. Discard this J15 plug and harness.
3. Connect one end of the red (+) wire from the new 33AH wire harness
to the red wire from the new J15 plug as shown. Connect the other
end of the red (+) wire to the positive (+) terminal on the battery as
shown.
4. Connect one end of the black (-) wire from the new 33AH wire
harness kit to the black wire from the new J15 plug as shown.
Connect the other end of the black (-) wire to the negative (-) terminal
on the battery as shown.
5. Reconnect the new J15 plug to the control board. NOTE: You may see
a small spark when plugging the J15 plug into the board.
6. Plug in the transformer.
