13.7.1 Requirements for Shielded Cable
The shielded cable must be used to satisfy the EMC requirements of CE marking. Shielded cables are classified into three-

13.7.2 Cabling Requirements
1. 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. If the motor cable is over 100 meters long, an output

2. It is recommended that all control cables be shielded.
3. It is recommended that the motor cables, power input cables and control cables be laid in different ducts. To avoid
electromagnetic interference caused by rapid change of the output voltage of the AC drive, the motor cables and other cables
must not be laid side by side for a long distance.

must not run across the AC drive.
5. The power input and output cables of the AC drive and weak-current signal cables (such as control cable) should be laid
vertically (if possible) rather than in parallel.
6. The cable ducts must be in good connection and well grounded. Aluminium ducts can be used to improve electric potential.
