HNSTALLATHON STEP 8
Electrical Requirements
To avoid installation difficulties, do not run the opener
until Step 9 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,.
To prevent p ossible SERIOUS iNJURY or DEATH from
electrocutionor fire:
• Besure power isnot connectedto the opener,and
disconnectpower to circuit BEFORE removing cover to
establishpermanentwiring connection.
- Garage door installationand wiring MUSTbe in compliance
with ALL local electrica[and building codes
• NEVER use an extensioncord, 2-wire adapter,or change
plugin ANYwayto make it fit outlet 9e sure the opener is
grounded_
PERMANENT WIRING
CONNECTION
If permanent wiring is required by your local code,
refer to the following procedure.
To make a permanent connectionthrough the 7/8" hole in
the top of the motor unit:
• Remove the motor unit cover screws and set the cover
aside_
o 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

installation
ALIGNING THE SAFETY REVERSING SENSORS
- Plug in the opener_ The indicatorlights in both the
sending and receiving eyes will glow steadily if wiring
connections and alignment are correcL
The sending eye amber indicator light will glow regardless
of alignment or obstruction.. I f 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
receivir_g eye indicator tight 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.
ff the door is already open, ff will not close_ The opener
lights will flash 10 times (see page 15),.
