INSTALLATION STEP 13

Electrical Requirements

To avoid installation difficulties, do not run the 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 (Models manufactured BEFORE
April 12, 2013)
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 top of the motor unit (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 cover and set aside.
3. Remove the attached green ground terminal.
4. Cut black and white wires and strip away 1/2 inch (1 cm) of
insulation, 3 inch (7.5 cm) before spade terminals.
5. Remove the power cord from opener.
6. Install a conduit or flex cable adapter to the 7/8 inch hole.
7. Run wires through conduit, cut to proper length and strip
insulation.
8. Attach with wire nuts provided. Attach the ground wire to the
green ground screw. The opener must be grounded.
9. Properly secure wire under plastic ties so that wire does not
come in contact with moving parts.
10. Reinstall the cover. DO NOT run garage door opener at
this time.
OPTION B PERMANENT WIRING (Models manufactured AFTER
April 12, 2013)
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 top of the motor unit (according to local
code):
1. Remove the motor unit cover screws and set the cover aside.
2. Remove the attached 3-prong cord.
3. Connect the black (line) wire to the screw on the brass
terminal; the white (neutral) wire to the screw on the silver
terminal; and the ground wire to the green ground screw. The
opener must be grounded.
4. Reinstall the 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.
• Garage door installation and wiring MUST be in compliance
with ALL local electrical and building codes.
• NEVER use an extension cord, 2-wire adapter, or change plug
in ANY way to make it fit outlet. Be sure the opener is
grounded.
