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

MOUNTING AND WIRING THE SAFETY SENSORS
• Slide a 1/4"-20xl/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.
