Power
To reduce the risk of electric shock, your garage door
opener has a grounding type plug with a third grounding
pin. This plug will only fit into a grounding type outlet.
If the plug doesn’t fit into the outlet you have, contact a
qualified electrician to install the proper outlet.
OPTION A: TYPICAL WIRING
1. Plug in the garage door opener into a grounded outlet.
2. DO NOT run garage door opener at this time.
OPTION B: PERMANENT WIRING CONNECTION
If permanent wiring is required by your local code, refer to
the following procedure.
To make a permanent connection through the 7/8 inch hole
in the back of the garage door opener (according to local
code):
1. Be sure power is NOT connected to the opener, and
disconnect power to circuit.
2. Remove the garage door opener from the torsion bar,
remove cover screws and set the cover aside.
3. Cut the line cord 6" (15.2 cm) above the strain relief.
4. Squeeze the strain relief and push into motor unit,
then remove the strain relief from the line cord.
5. Install a 90° conduit (not provided) or flex cable
adapter (not provided) to the 7/8" hole. Reinstall
garage door opener to torsion bar.
6. Run wires through conduit, cut to proper length and
strip insulation.
7. Strip 1/2" (1.3 cm) of insulation from the existing
black, white and green wires.
8. Connect the line to the black wire and neutral to the
white wire with wire nuts (not provided). Connect
ground wire to the green ground screw.
9. Properly secure wires under plastic ties so that they
do not come into contact with moving parts.
10. Reinstall cover.
To prevent possible SERIOUS INJURY or DEATH from
electrocution or fire:
• Be sure power is NOT connected to the opener, and
disconnect power to circuit BEFORE removing cover
to establish permanent wiring connection.

compliance with ALL local electrical and building
codes.
