Installation Step 10
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:
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 until
Step 11 below.
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
If the sending eye indicator light does not glow steadily after
1.
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.
•
If the sending eye indicator light glows steadily but the
2.
receiving eye indicator light doesn’t:
Check alignment.
•
Check for an open wire to the receiving eye.
•
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.
