Mounting And Wiring The Safety Reversing Sensors - Craftsman 139.53993DM Manual Del Propietário

MOUNTING AND WIRING THE SAFETY REVERSING SENSORS

• Slide 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).
• 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 (Figure 6).
2. Run the wires through wire clip at the top of the rails.
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. If you choose
this option, follow instructions 1-3 on page 20.
