7.4 Connecting the protective conductor for the individual
components
!
Caution
The components shown in Fig. 7-1 require connection to a protective conductor. The
individual components must be connected to the central grounding point.
Make always sure that a low-resistance connection is provided to the protective conductor.
Minimum cross-section of the cable to the protective conductor: 10 mm

Whereas all remaining components are grounded via a grounding screw, the PP72/48 I/O
module must be connected directly to the central grounding point via the mounting plate
(installation acc. to EN 60204). If no grounding can be provided via the mounting plate,
it must be connected to the central grounding point via an additional line (cross-section
> 10 mm

).
