Application example:
A = hazardous area
S = minimum safety distance
6.3 Installation of the safety light grids
These versions of OY90xS safety light grids are suitable for access
prevention for entire bodies�
They must not be used for the protection of hands or body parts!
The minimum safety distance (S) is determined using the
following formula:
S = 1600 (t + t
2
) + 850
The height of the upper light beam (H1) measured from the
reference level (G) must not be less than 900 mm while the
height of the lowest light beam (H2) must not exceed 300
mm (ISO 13855)�
A = hazardous area
Hx = height
S = minimum safety distance
G = reference level
