INSTALLATION STEP 10
Electrical Requirements
To avoid installation diffi culties, do not run the opener
until Step 11 below.
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" 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
until Step 11 below.
RIGHT WRONG
To prevent possible SERIOUS INJURY or DEATH from
electrocution or fi re:
• 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 fi t outlet. Be
sure the opener is grounded.

TROUBLESHOOTING THE SAFETY
REVERSING SENSORS
1. If the sending eye indicator light does not glow steadily
after installation, check for:
• Electric power to the opener.
• A short in the white or white/black wires. These can
occur at staples, or at opener connections.
• Incorrect wiring between sensors and opener.
• A broken wire.
2. If the sending eye indicator light glows steadily but the
receiving eye indicator light doesn’t:
• Check alignment.
• Check for an open wire to the receiving eye.
3. If the receiving eye indicator light is dim, realign either
sensor.
NOTE: When the invisible beam path is obstructed or
misaligned while the door is closing, the door will reverse.
If the door is already open, it will not close. The opener
lights will fl ash 10 times. (See page 15.)

ALIGNING THE SAFETY REVERSING SENSORS
• Plug in the opener. The indicator lights in both the
sending and receiving eyes will glow steadily if wiring
connections and alignment are correct.
The sending eye amber indicator light will glow regardless
of alignment or obstruction. If the green indicator light in
the receiving eye is off, dim, or fl ickering (and the invisible
light beam path is not obstructed), alignment is required:
• Loosen the sending eye wing nut and readjust, aiming
directly at the receiving eye. Lock in place.
• Loosen the receiving eye wing nut and adjust the
sensor until it receives the sender’s beam. When the
green indicator light glows steadily, tighten the wing
nut.
