INSTALLATION STEP 10
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 until Step 11 below.
INSTALLATION STEP 11
Complete the 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 until it receives the sender’s beam. When
the green indicator light
glows steadily
, tighten the
wing nut.
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.

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.)
