Legend Screened cable Unscreened cable with restriction II F 2-25 3ADW000072R0601 DCS600 System description e f Filter in a grounded line (earthed TN or TT network) The filters are suitable for grounded lines only, for example in public European 400 V lines. According to EN 61800-3 filters are not needed in insulated industrial lines with own supply transformers. Furthermore they could cause safety risks in such floating lines (IT networks). Three - phase filters EMC filters are necessary to fulfil the standard for emitted interference if a converter shall be run at a public low voltage line, in Europe for example with 400 V between the phases. Such lines have a grounded neutral conductor. ABB offers suitable three - phase filters for 400 V and 25 A...600 A and 500 V filters for 440 V lines outside Europe. The filters can be optimized for the real motor currents: IFilter = 0.8 • IMOT max ; the factor 0.8 respects the current ripple. Lines with 500 V to 1000 V are not public. They are local lines inside factories, and they do not supply sensitive electronics. Therefore converters do not need EMC filters if they shall run with 500 V and more.

They can be supplied by two of the three input phases of the armature supply converter. Then a field supply unit does not need its own filter. If the phase to neutral voltage shall be taken (230 V in a 400 V line) then a separate filter is necessary. ABB offers such filters for 250 V and 6...30 A.
