9.4 Shielded Cable
9.4.1 Requirements for the Shielded Cable
The shielded cable must be used to satisfy the EMC requirements. Shielded cables are
classied into three-conductor cable and four-conductor cable. If conductivity of the cable
shield is not sufficient, add an independent PE cable, or use a four-conductor cable, of
which one phase conductor is PE cable.
The three-conductor cable and four-conductor cable are shown in the following gure.

The motor cable and PE shielded conducting wire (twisted shielded) should be as short
as possible to reduce electromagnetic radiation and external stray current and capacitive
current of the cable.
To suppress emission and conduction of the radio frequency interference effectively, the
shield of the shielded cable is cooper braid. The braided density of the cooper braid should
be greater than 90% to enhance the shielding efciency and conductivity, as shown in the
following gure.

It is recommended that all control cables be shielded. The grounding area of the shielded
cable should be as large as possible. A suggested method is to x the shield on the metal
plate using the metal cable clamp so as to achieve good contact, as shown in the following
gure.
