Shielded cables are classified into three-conductor cable and four-conductor cable.
Page 258 MD380 User Manual The installation precautions are as follows: • Symmetrical shielded cable is recommended. The four-conductor shielded cable can also be used as an input cable. • 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.
