INSTALLATION STEP 11
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.
To make a permanent connection through the 7/8" hole in
the top of the motor unit (according to local code):
• Remove the motor unit cover screws and set the cover
aside.
• Remove the attached green ground terminal.
• Cut black and white wires and strip away 1/2" (1 cm) of
insulation, 3" (7.5 cm) before spade terminals.
• Remove the power cord from opener.
• Install a conduit or flex cable adapter to the 7/8" hole.
• Run wires through conduit, cut to proper length and strip
insulation.
• Attach with wire nuts provided. Attach the ground wire to
the green ground screw. The opener must be grounded.
• 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.
RIGHT
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.

Complete Safety Reversing Sensor
Installation
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 flickering (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
vertically and/or horizontally until it receives the sender’s
beam. When the green indicator light glows steadily,
tighten the wing nut.
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 blink 10 times (if bulbs are not installed, 10 clicks
can be heard). See page 11.
