    General information related to determining detection zone contours Shadow effects (e.g. surfaces or areas located behind stationary objects) must be considered. As a rule, insufficient safeguarding must be adequately supplemented by further safety measures such as protective grid, light curtains, and the like! Access to the detection zone in the dangerous area is not permitted.
