9.4 EMC limit value classes
Please note that these limit value classes are only reached if the standard pulse frequency (6kHz) is being
used and the length of the shielded motor cable does not exceed the permissible limits.
In addition, it is essential to use wiring suitable for EMC. The motor cable shielding must be applied on both
sides (frequency inverter shield angle and the metal motor terminal box).
