Installation Step 4 (Continued)

Install the Safety Reversing Sensor

Mounting and Wiring the Safety Sensors

•Slide a 1/4"-20x1/2" carriage bolt head into the slot on both sensors. Use wing nuts to fasten sensors to brackets, with lenses pointing toward each other across the door. Be sure the lens is not obstructed by a bracket extension. See Figure 4.

•Finger tighten the wing nuts.

Recommended Wire Routing

1.Using insulated staples, run the wires from both sensors to the rail at the door header (see Figure 5).

2.Cross and twist the two wires where they meet the rail (see inset A). Run the wires inside the channels at the top of the rail, along each side, to the power unit and pull taut (see inset B). Do not use the lower (trolley) channels.

NOTE: If your access door is near the garage door, you may choose to install the door control at this time and run the door control wire along the rail with the sensor wires. Use one rail channel for the door control wire and the other channel for both sensor wires. If you choose this option, follow instructions 1-3

on page 21 now.

3.Thread the wires through the tabs on top of the drive shaft cover.

4.With your screwdriver tip, tuck the wires snugly into the rail channels. You will complete the wiring in Installation Step 7.
