4-1-3. Distance from Reflective Surfaces

Install the sensor system so that it is not affected by reflective surfaces. Failure to do so
may hinder detection, resulting in serious injury.
Install the sensor system at distance D or further from highly reflective surfaces such as metallic walls,
floors, ceilings, or workpieces, as shown below.
