INSTALLATION STEP 10

Electrical Requirements

To avoid installation diffi culties, 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 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.

If permanent wiring is required by your local code, refer
to the following procedure.

To make a permanent connection through the 7/8" (2 cm)
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 diffi culties, do not run the opener
at this time.

To prevent possible SERIOUS INJURY or DEATH from
electrocution or fi re:
• Disconnect ALL electric and battery power BEFORE

performing ANY service or maintenance.

• 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 fi t outlet. Be
sure the opener is grounded.
