2.13.5 Grounding
The installation of the module must be performed acc. to EN 60204.
The user must ground the power supply voltages. From terminal X1, pin 2
(MEXT1) or X6-1, pin 12 (MEXT2) it is necessary to establish a link with a
central grounding point of the system.
If a large-area, permanent metallic connection with the central ground point
through the rear panel is not possible, the module must be connected to the
grounding rail by means of a line (cross section >10mm

).

Caution
A protective conductor must be connected.
The housing front has an M6 screw bottom right for connecting the protective
conductor. See Subsection 2.13.1, page 2-105.
