All cables from and to the ETAMATIC must be shielded (with the exception of the 230 V cable).
Connect the shielding to PE by the shortest possible route.

Two rails are fitted to the left and right side of the terminal strips and parallel to them on the
unit's rear side. Connect all shieldings to these rails. Also connect the PE to this point from
the outside.
