Screen Earth Kit - Eaton PowerXL DC1 20 Series Installation Manual

3.5.4 Screen earth kit

Cables that are not screened work like antennas (sending, receiving).
￫
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.
The effectiveness of the cable screen depends on a good screen connection
and a low screen impedance.
￫
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).
