PRE-WIRED INSTALLATION
1. Cut the end of the safety reversing sensor wire, making sure there is enough wire to reach the
pre-installed wires from the wall.
2. Separate the safety reversing sensor wires and strip 7/16 inch (11 mm) of insulation from each
end. Choose two of the pre-installed wires and strip 7/16 inch (11 mm) of insulation from each
end. Make sure that you choose the same color pre-installed wires for each sensor.
3. Connect the pre-installed wires to the sensor wires with wire nuts making sure the colors
correspond for each sensor. For example, the white wire would connect to the yellow wire and
the white/black wire would connect to the purple wire.
4. At the garage door opener, strip 7/16 inch (11 mm) of insulation from each end of the wires
previously chosen for the safety reversing sensors. Twist the like-colored wires together.
5. Insert the wires connected to the white safety sensor wires to the white terminal on the garage
door opener. Insert the wires that are connected to the white/black safety sensor wires to the
grey terminal on the garage door opener.
