In summary, there are three usual variations of mounting the scan plane for the
SafeZone Mini device. The optimal variation depends on the related
application.
Table 8
helps make the selection.

ATTENTION: If scan planes are at a height of more than 300 mm (11.81 in.)
verify that people cannot reach the hazardous area by crawling underneath
the scan plane.
If you mount the protective device higher than 300 mm (11.81 in.), you must
help prevent crawling beneath with additional measures. For applications
that are accessible to the public, the mounting height must be reduced to
200 mm (7.87 in.)
(1) See the appropriate regulations.
Calculate the Supplement C
• If there is enough empty space in front of your machine or system, use
1200 mm (47.2 in.) for the supplement C.
• If the minimum distance is to be kept as small as possible, calculate C
with the following formula:
C = 1200 mm – (0.4 × H
Here H
is the height at which the protective field is mounted.
D
IMPORTANT The minimum supplement C to help prevent reaching over is 850 mm
(33.5 in.) (arm length).
