6.2 EMC-compliant Installation
For cable selections in different EMC levels, see
To comply with the EMC levels, use a grommet when installing the motor cable at the two ends. For the EMC level C2, it is necessary to
have a 360º grounding of the shield with grommets in the motor end.
Table 14: Recommendations for Cables
Cable
Category C2
type
Motor ca-
A symmetrical power cable with a compact low-impe-

dance shield.
A cable for the specified mains voltage.
We recommend an MCCMK, or an EMCMK cable. See

We recommend that the cable transfer impedance
(1–30 MHz) is a maximum of 100 mΩ/m.
Mains ca-
A power cable for a fixed installation.
ble
A cable for the specified mains voltage.
A shielded cable is not necessary.
We recommend an MCMK cable.
Control
A shielded cable with a compact low-impedance shield, for example a JAMAK, or an SAB/ÖZCuY-O cable.
