INSTALLATION STEP 13
CONNECT POWER
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.
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.
THERE ARE TWO OPTIONS FOR CONNECTING POWER:
OPTION A - TYPICAL WIRING
1. Plug in the garage door opener into a grounded outlet.
2. DO NOT run garage door opener at this time.
OPTION B - PERMANENT WIRING
If permanent wiring is required by your local code, refer to the
following procedure. To make a permanent connection through the
7/8-inch hole in the top of the motor unit (according to local code):
1. Remove the motor unit cover screws and set the cover aside.
2. Remove the attached 3-prong cord.
3. 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.
4. Reinstall the cover.

INSTALLATION STEP 14
ALIGN THE SAFETY REVERSING SENSORS
IMPORTANT: The safety reversing sensors MUST be connected
and aligned correctly before the garage door opener will move in
the down direction.
When the garaged door opener has power, check the safety reversing
sensors. If the sensors are aligned and wired correctly, both LEDs will
glow steadily.

Sending sensor - amber LED
To align the safety reversing sensors:
1. Loosen the wing nuts.
2. Adjust the sensors up or down until both LEDs glow steady
indicating alignment.
3. Tighten the wing nut to secure the sensor.

SAFETY SENSOR TROUBLESHOOTING
If either of the sensor LEDs are off, there is no power to the
sensor:
1. Check that you have power to the garage door opener.
2. Check the sensor wire is not shorted or broken.
3. Check that the sensors is wired correctly; white wires to white
terminal and white/black wires to grey terminal.

If the green receiving sensor LED is blinking, the sensors are
obstructed or misaligned:
1. Check for obstructions in the sensor light beam.
2. Align the sensors.
3. If the receiving sensor (green LED) faces direct sunlight,
switch the receiving sensor with the sending sensor and
repeat STEP 12 Install the Protector System® on page 25 to
assure proper operation.
ENSURE THE DOOR CONTROL IS WIRED
CORRECTLY
If the door control has been installed and wired correctly, the
command LED on the Motion- Detecting Control Panel will blink.
