Connect Power

To avoid installation difficulties, do not
run the garage door opener at this time.
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.
There are two options for connecting
power:
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.
1. To make a permanent connection
through the 7/8 inch hole in the back
of the garage door opener (according
to local code):
2. Be sure power is NOT connected to
the opener, and disconnect power to
circuit.
3. Remove the garage door opener from
the torsion bar, remove cover screws
and set the cover aside.
4. Cut the line cord 6" (15.2 cm) above
the strain relief.
5. Squeeze the strain relief and push into
garage door opener, then remove the
strain relief from the line cord.
6. Install a 90° conduit (not provided)
or flex cable adapter (not provided)
to the 7/8" hole. Reinstall garage door
opener to torsion bar.
7. Run wires through conduit, cut to
proper length and strip insulation.
8. Strip 1/2" (1.3 cm) of insulation from
the existing black, white and green
wires.
9. 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.
10. Properly secure wires under plastic
ties so that they do not come into
contact with moving parts.
11. Reinstall cover.
