To satisfy the EMC requirements, use shielded cables. Shielded cables are classified
into three‑conductor cables and four‑conductor cables, as shown in the following
figure. If the shield of the three‑conductor cable cannot provide sufficient
conductivity, add an independent PE cable. or use a four‑conductor cable that
contains a PE conductor. To suppress radio frequency interference effectively, use
shielded cables with concentric copper‑braided shield. The weaving density of the
copper‑braided shield should be greater than 90% to enhance the shielding efficiency
and conductivity.
