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.)
