Connect Power

To avoid installation diffi culties, 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 fi t into a grounding type outlet. If
the plug doesn't fi t into the outlet you have,
contact a qualifi ed 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.
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. Remove the attached green ground
terminal.
4. Cut black and white wires and strip
away 1/2 inch (1.3 cm) of insulation,
3 inch (7.6 cm) before spade terminals.
5. Remove the power cord from the
garage door opener.
6. Install a 90° conduit or fl ex cable
adapter to the 7/8 inch hole. Reinstall
garage door opener to torsion bar.
7. Run wires through conduit, cut to
proper length and strip insulation.
8. Attach with wire nuts provided.
9. Properly secure wire under plastic ties
so that wire does not come in contact
with moving parts.
10. Reinstall the cover.
