6.2 EMC-compliant Installation
For cable selections in different EMC levels, see table 14 .
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.

Motor ca-
ble 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
illustration 9 .
We recommend that the cable transfer impedance
(1–30 MHz) is a maximum of 100 mΩ/m.
A symmetrical power cable with a concentric protection wire.
A cable for the specified mains voltage.
We recommend an MCMK cable. See illustration 9 .
Mains ca-
ble A power cable for a fixed installation.
A cable for the specified mains voltage.
A shielded cable is not necessary.
We recommend an MCMK cable.
Control
cable A shielded cable with a compact low-impedance shield, for example a JAMAK, or an SAB/ÖZCuY-O cable.
