2-1-3 Distance from Reflective Surfaces
WARNING
Be sure to install the F3S-B to minimize the effects of reflection from reflective surfaces.
Failure to do so will cause detection to fail and may result in serious injury.
Install the F3S-B with minimum Distance D shown below from reflective surfaces (highly reflective sur-
faces) like metal walls, floors, ceilings, and work pieces.
