INSTALLATION STEP 7

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.
If permanent wiring is required by your local code,
refer to the following procedure.
RIGHT
To make a permanent connection through the 7/8" hole in
the back of the motor unit (according to local code):
• Remove the opener from the torsion bar, remove cover
screws and set the cover aside.
• Remove the attached green ground terminal.
• Cut black and white wires and strip away 1/2" (1.3 cm)
of insulation, 3" (7.6 cm) before spade terminals.
• Remove the power cord from unit.
• Install a 90 conduit or flex cable adapter to the 7/8"
o
hole. Reinstall opener to torsion bar.
• Run wires through conduit, cut to proper length and strip
insulation.
• Attach with wire nuts provided.
• Properly secure wire under plastic ties so that wire does
not come in contact with moving parts.
• Reinstall the cover.
To avoid installation difficulties, do not run the opener
at this time.
WRONG
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.
