How to size your VLT
LC and RFI filter (module)
The LC and RFI filter module in IP 20 enclosure is
designed to be built in with the VLT frequency
converter itself. The filter contains the following:
- RFI filter to reduce electro-magnetic
interference
- LC filter to reduce the acoustic noise level from the
motor and make it possible to use long motor
cables up to 300 m.
- Motor filter (motor RFI filter) to reduce the electro-
magnetic interference from the motor cable.
Equipped with the IP 20 LC and RFI filter
(195H6526 and 195H6527), the VLT 2000 Series
meets the EN 55011, Group 1, Class A requirements
of EMC emission.
The EMC emission specifications are complied with
by using up to 100 m unscreened motor cable.

Motor coils in IP 00 and IP 10 enclosure contain only
one motor coil, making it possible to use long motor
cables up to 300 m. These motor coils must be
installed separately (not for co-building with the VLT
frequency converter).
RFI and motor filter (module)
The RFI and motor filter module in IP 20 enclosure is
designed to be built in with the VLT frequency
converter itself. The filter contains the following:
- RFI filter to reduce electro-magnetic
interference.
- Motor coils making it possible to use long motor
cables.
- Motor filter (motor RFI filter) to reduce the electro-
magnetic interference from the motor cable.
The VLT 2000 Series basic units meet EMC immunity
requirements as laid down in the IEC 1000-4
standards, but do not meet any EMC emission
requirements.
Equipped with the IP 20 RFI and motor filter
(195H6522, 195H6523, 195H6524, 195H6525),
the VLT 2000 Series meets the EN 55011, Group 1,
Class A requirements of EMC emission.
The EMC emission specifications are complied with
by using up to 100 m unscreened motor cable.
