for inverter modules to 7.5 kW.
For inverter modules 11 to 90 kW a wide range of filters is availa-
ble to ensure conformance to IEC 55011.
• All devices conform to the product norm
EN618000-3 for speed-adjustable electric drives.
1) EMC = Electromagnetic compatibility
2) Motor cable length - See section 6.4
