To avoid installation diffi culties, do
not run the garage door opener at

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

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

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
