The specified interference immunity and spurious emission are only guaranteed if
the bus shield is fully effective.
This includes the connecting of shields with the metallic terminals of the
SITRANS T3K PA but also the laying of shields to the terminal boxes, distributors,
DP/PA couplers or DP/PA link.
A suitable potential equalizer must be provided to avoid potential differences
between the individual system parts and thus endangering or affecting the
functioning. You fill find hints for dimensioning and execution in DIN VDE 0100
