grounding pin. This plug will onl fit into a grounding
t pe outlet. If the plug doesn't fit into the outlet ou
have, contact a qualified electrician to install the
proper outlet.
If permanen wiring is required by your local
code, refer o he 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 mus be
grounded.
• Reinstall the cover.
To avoid ins alla ion difficul ies, do no run he
opener a his ime.
RIGHT WRONG
To prevent possible SERIOUS IN URY 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.

IMPORTANT INFORMATION ABOUT
THE SAFETY REVERSING SENSOR
When properl connected and aligned, the sensor
will detect an obstacle in the path of its electronic
beam. The sending e e (with an orange indicator
light) transmits an invisible light beam to the
receiving e e (with a green indicator light). If an
obstruction breaks the light beam while the door is
closing, the door will stop and reverse to full open
position, and the opener lights will flash 10 times.
The units must be installed inside the garage so that
the sending and receiving e es face each other
across the door, no more than 6" above the floor.
Either can be installed on the left or right of the door
as long as the sun never shines directl into the
receiving e e lens.
The mounting brackets are designed to clip onto the
track of sectional garage doors without additional
hardware.
If it is necessar to mount the units on the wall, the
brackets must be securel fastened to a solid
surface such as the wall framing. Extension brackets
(see accessories) are available if needed. If
installing in masonr construction, add a piece of
wood at each location to avoid drilling extra holes in
masonr if repositioning is necessar .
The invisible light beam path must be unobstructed.
No part of the garage door (or door tracks, springs,
hinges, rollers or other hardware) ma interrupt the
beam while the door is closing.
• Be sure power is not connected to the garage door
opener BEFORE installing the safety reversing sensor.
• To prevent SERIOUS IN URY or DEATH from a closing
garage door:
– Correctly connect and align the safety reversing
sensor. This required safety device MUST NOT be
disabled.
– Install the safety reversing sensor so beam is NO
HIGHER than 6" above garage floor.

INSTALLING THE BRACKETS
Be sure power o he opener is disconnec ed.
Install and align the brackets so the sensors will face
each other across the garage door, with the beam no
higher than 6" above the floor. The ma be installed
in one of three wa s, as follows.
Garage door track installation (preferred):
• Slip the curved arms over the rounded edge of
each door track, with the curved arms facing the
door. Snap into place against the side of the track.
It should lie flush, with the lip hugging the back
edge of the track, as shown in Figure 1.
If our door track will not support the bracket
securel , wall installation is recommended.
Wall installation:
• Place the bracket against the wall with curved
arms facing the door. Be sure there is enough
clearance for the sensor beam to be unobstructed.
• If additional depth is needed, an extension bracket
(see Accessories) or wood blocks can be used.
• Use bracket mounting holes as a template to
locate and drill (2) 3/16" diameter pilot holes on
the wall at each side of the door, no higher than 6"
above the floor.
• Attach brackets to wall with lag screws
(not provided).
• If using extension brackets or wood blocks, adjust
right and left assemblies to the same distance out
from the mounting surface. Make sure all door
hardware obstructions are cleared.
Floor installation:
• Use wood blocks or extension brackets (see
Accessories) to elevate sensor brackets so the
lenses will be no higher than 6" above the floor.
• Carefull measure and place right and left
assemblies at the same distance out from the wall.
Be sure all door hardware obstructions are
cleared.
• Fasten to the floor with concrete anchors as
shown.

Figure 4MOUNTING AND WIRING THE SAFETY SENSORS
• Slide a 1/4"-20x1/2" carriage bolt head into the slot
on each sensor. Use wing nuts to fasten sensors to
brackets, with lenses pointing toward each other
across the door. Be sure the lens is not obstructed
b a bracket extension (Figure 4).
• Finger tighten the wing nuts.
•Run the wires from both sensors to the opener. Use
insulated staples to secure wire to wall and ceiling.
• Strip 7/16" of insulation from each set of wires.
Separate white and white/black wires sufficientl to
connect to the opener quick-connect terminals.
Twist like colored wires together. Insert wires into
quick-connect holes: white to white and white/black
to black (Figure 5).
ALIGNING THE SAFETY SENSORS
•Plug in the opener. The indicator lights in both the
sending and receiving e es will glow steadily if
wiring connections and alignment are correct.
The sending e e orange 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 e e wing nut and readjust,
aiming directl at the receiving e e. Lock in place.
• Loosen the receiving e e wing nut and adjust
sensor until it receives the sender’s beam. When
the green indicator light glows steadil , tighten the
wing nut.
TROUBLESHOOTING THE SAFETY SENSORS
1. If the sending e e indicator light does not glow
steadil 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 e e indicator light glows steadil but
the receiving e e indicator light doesn't:
• Check alignment.
• Check for an open wire to the receiving e e.
3. If the receiving e e 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 blink 10 times. (If bulbs are not
installed, 10 clicks can be heard. See page 17.

INSTALLATION STEP 11
Fasten the Door Bracket
Follow instructions which appl to our door t pe
as illustrated below or on the following page.
A horizon al reinforcemen brace should be long
enough o be secured o wo or hree ver ical
suppor s. A ver ical reinforcemen brace should
cover he heigh of he op panel.
Figure 1 shows one piece of angle iron as the
horizontal brace. For the vertical brace, 2 pieces of
angle iron are used to create a U-shaped support.
The best solution is to check with our garage door
manufacturer for an opener installation door
reinforcement kit.
NOTE: Many door reinforcement kits provide for
direct attachment of the clevis pin and door arm. In
this case you will not need the door bracket; proceed
to Step 12.
SECTIONAL DOORS
1. Center the door bracket on the previousl marked
vertical centerline used for the header bracket
installation. Note correct UP placement, as
stamped inside the bracket.
2. Position the top edge of the bracket 2"-4" below
the top edge of the door, OR directl below an
structural support across the top of the door.
3. Mark, drill holes and install as follows, depending
on our door’s construction:
Metal or light weight doors sing a vertical angle
iron brace between the door panel s pport and
the door bracket:
• Drill 3/16" fastening holes. Secure the door bracket
using the two 1/4"-14x5/8" self-threading screws.
(Figure 2A)
• Alternatel , use two 5/16" bolts, lock washers and
nuts (not provided). (Figure 2B)
Metal, ins lated or light weight factory reinforced
doors:
• Drill 3/16" fastening holes. Secure the door bracket
using the self-threading screws (Figure 3).
Wood Doors:
• Use top and bottom or side to side door bracket
holes. Drill 5/16" holes through the door and
secure bracket with 5/16"x2" carriage bolts, lock
washers and nuts (not provided). (Figure 4)
NOTE: The 1/4"-14x5/8"
self-threading screws are
not intended for use on
wood doors.
To prevent damage to garage door, reinforce inside of
door with angle iron both vertically and horizontally.
