so-called chassis ground (commonly known as PGND). This chassis
ground must be securely connected to the earth so that the faradism

Ground your switch as follows:
When a grounding strip is available at the installation site,
attach one end of the yellow-green grounding cable of the
switch to the grounding screw on the grounding strip and
fasten the captive nut. (Note that the fire main and lightning

The grounding cable of the switch should be connected to
the construction engineering ground of the equipment
room.)
