2 Installation
2.1 Mount the Device
1. If a bracket is needed, mount the device onto the bracket.
2. Mount the device (or the device and the bracket) to the machine or equipment at the desired location. Do not tighten
the mounting screws at this time.
3. Check the device alignment.
4. Tighten the mounting screws to secure the device (or the device and the bracket) in the aligned position.
2.2 Wiring Diagrams
Follow the wiring diagram that is appropriate for your application.
Opposed-Mode Models: The following wiring diagrams apply to the receivers. The three wiring diagrams that include
remote input apply to the emitters.
