MOUNTING AND WIRING THE SAFETY SENSORS

ïSlide 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 by a bracket extension (Figure 5).

ïFinger tighten the wing nuts.

Recommended Wire Routing

1.Using insulated staples, run the wires from both sensors to the rail at the door header (Figure 6).

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 motor unit. Do not use the lower (trolley) channels. Use a screwdriver tip to tuck the wires snugly into the 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 16 now.

3.Pull wires taut across the top of the chassis and insert into the opening above the terminal block (see inset B). You will complete the wiring in Installation Step 7.
