Interference emission

The cable length must be as short as possible for EMC-compliant installation. SEW‑EURODRIVE recommends using low-capacity cables. To comply with limit class C2 or C3 according to EN 61800‑3, the measures listed below must be taken.

Limit value class C2

Inverter

INFORMATION

The EMC limit values for interference emission are not specified for voltage supply systems without grounded star point (IT systems). The efficiency of filters is severely limited.
