Step 16: Install Wiring for Wired Infrared Safety Sensor
Identify which side of the garage door opening (if any) the sun is “likely” to shine on to. Since sunlight may affect infrared safety sensors, you should mount the sending unit on the side of the door opening exposed to the sun.
Uncoil the wires from the infrared safety sensors and route the wire up the garage wall across the ceiling and down to the back of the power head, as illustrated. Tack the wires in place using staples. Take care to run the wires in a location where they will not interfere with the operation of the door and do not staple through wire. Be sure to leave about 12” of excess wire at each end so you will have enough slack wire to mount units.
Note: If wires must be lengthened or spliced into pre- wired installation, use wire nuts or a suitable connec- tor.
Step 17: Connecting Wired Infrared Safety Sensor to Opener
Connect Infrared Safety Sensors to power head as per diagram. Shorten the wires as necessary and separate the wire ends. Strip about 1/2" of insulation off each wire and attach the wires to the proper terminal screws, then tighten securely, using a small blade screwdriver.
One wire has marking on it (numbers, black stripe, etc). Be sure to observe polarity. Apply tension to external wires to test for secure connection. Check that the wires are stapled in place.
