3.5.4 Screen earth kit
Cables that are not screened work like antennas (sending, receiving).
The effectiveness of the cable screen depends on a good screen connection
and a low screen impedance.
→
For a proper EMC connection, cables emitting interference (e.g.
motor cables) and susceptible cables (analog signal and
measured values) must be screened and laid separately from
each other.
→
Use only screens with tinned or nickel-plated copper braiding.
Screens made of steel braids or metal conduits are either not
suitable or suitable only to a limited extent (depending on the
EMC environment).
→
Control and signal lines (analog, digital) should always be
grounded on one end, in the immediate vicinity of the supply
voltage source (PES).
