4.3 Mounting Procedures for COMPACT Light Grids for Vertical Access Protec-
tion (Series C300/4, C400/3, C500/2, C301/4, C401/3 and C501/2)
The installation of COMPACT light grids shall ensure that hazard locations cannot be accessory by
crawling under, between, reaching over the planes of light, or by reaching through the planes of
light. The number of planes of light and the spacing between these depend on the risk assessment
as well as machinery-specific regulations such as e.g. EN 775. The EN 999 proposes the following
variants:
Number of
beams
4
3
2
The minimum clearance is calculated as follows:
S = (1.6 mm/ms x T) + 850 mm
