INSTALLATION STEP 9
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.
RIGHT
If permanent wiring is required by your local code, refer to the
following procedure.
To make a permanent connection through the 7/8" hole in the top
of the motor unit:
• Remove the motor unit cover screws and set the cover aside.
• Remove the attached 3-prong cord.
• 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.
• 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.
