5.4.4.1 Recessed installation (undercut) under the machine table
The undercut must be at least as deep as the zone not monitored by the detection zone
lateral to and in front of the scanner. The minimum depth Z
possible to recess the scanner, this is allowed up to a maximum of 40 mm; the depth of
the undercut is reduced by the depth value of the recess. If the mounting system is being
used, the necessary dimensions of the undercut depth must be increased accordingly
(see Chapter 14.13 and 14.14). The height of the undercut must be limited to prevent
people from being able to step beneath it.
