Electrical and Wiring 10 - Permanent Wiring
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
l
permanent wiring connection.
Garage door installation and wiring MUST be in compliance with ALL local electrical and building codes.
l
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.
l
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 align the safety reversing sensors, see Electrical and Wiring step 13 in the Installation Manual. If LEDs
are still flashing or not glowing, follow the directions below.
Electrical and Wiring 14 - Align the Safety Reversing Sensors
The door will not close if the sensors have not been installed and aligned correctly. The LEDs in both sensors will glow steadily if
they are aligned and wired correctly.
If the amber LED on the sending sensor is not glowing:
1. Make sure there is power to the garage door opener.
2. Make sure the sensor wire is not shorted/broken.
3. Make sure the sensor has been wired correctly: white wires to white terminal and white/black wires to grey terminal.
