Screening
The shield should be connected on both sides to a metallized connector
hood. If non-metallized connector hoods are used, the shield may also
be connected to pin 1, but this is not recommended due to interferences,
because the data lines should be completely covered by the shield (if
possible). It should be noticed, however, that earthing on both sides may
require an equipotential bonding conductor with a cross section of 10
times that of the shield in order to compensate for earth potential variations
and to prevent equalizing currents on the cable shield! This is especially
important, if the PCS and the programmable controller are not connected
to the same common point (if they are for example installed in different
control cabinets).
