Mounting
Supplement C for protection against reaching over
With a protective field installed horizontally, there is a risk that people may reach over the
p
rotective field and in this way reach the hazardous area before the S300 shuts down the
dangerous state. For this reason the calculation of the minimum distance must take into
account a supplement to prevent persons from finding themselves in a hazardous situa-
tion by reaching over (see EN ISO 13857) before the S300 triggers.
The necessary supplement for the minimum distance is dependent on the height of the
scan plane for the protective field. At low heights  the supplement is larger than at grea-
ter heights  and .
In summary there are three usual variations of mounting the scan plane for the S300. The
optimal variation depends on the related application. Tab. 21 provides assistance making
the selection.

In case of scan planes at a height of more than 300 mm ensure that people cannot
reach the hazardous area by crawling underneath the scan plane!
If you mount the protective device higher than 300 mm, you must prevent crawling be-
neath by means of additional measures. For applications that are accessible to the public,
the mounting height may need to be reduced to 200 mm (on this subject see the appropri-
ate regulations).
