INSTALLATION STEP 8
Electrical Requirements
To avoid installation difficulties, 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 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 at this time.
To prevent possible SERIOUSINJURYor DEATHfrom
electrocution or fire:
• Besure power is not connectedto the opener,and
disconnect powerto circuit BEFOREremoving cover to
establish permanentwiring connection.
• Garagedoor installation and wiring MUSTbe in compliance
with ALL localelectrical and building codes.
• NEVERusean extensioncord, 2-wire adapter,or change
plug in ANYwayto make it fit outlet. Besurethe opener is
grounded.

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 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 flash 10 times. (See page 15.)
