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. 1 Safety reversing sensor wires 3 Safety reversing sensor wires White White/Black 4 2 Pre-installed wires 5 Yellow Purple 7/16" (11 mm) 7/16" (11 mm) Wire nuts (not provided) Pre-installed wires Yellow (for example) Purple (for example) Yellow Purple To insert or remove the wires from the terminal, push in the tab with a screwdriver tip. 26

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.
