INSTALLATION STEP 8
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 at this time.
To prevent possible SERIOUSINJURY or DEATHfrom
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.
• NEVERuse an extension cord, 2-wire adapter, or
change plug in any way to make it fit outlet. Be sure
the opener is grounded.

Complete the Safety Reversing
Sensor Installation
ALIGNING THE SAFETY 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 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.)
