Shielding, grounding, and equipotential bonding

Important notes regarding shielding, grounding and equipotential bonding
The correct installation and connection of the cable shields and protective conductors is of
crucial importance, not only for personal safety but also for noise emission and noise
immunity.
Risk of electric shock!
Hazardous touch voltages can be present at unused cores and shields if they have not
been grounded or insulated.

WARNING
Connect the cable shields to the respective housings through the largest possible
surface area. Use suitable clips, clamps or screw couplings to do this.
Connect unused conductors of shielded or unshielded cables and their associated
shields to the grounded enclosure potential at one end as minimum.
Alternatively:
Insulate conductors and their associated shields that are not used. The insulation must
be able to withstand the rated voltage.
