2.6 Radio interference suppression filter
DC1-S2…F… variable frequency drives feature an internal radio interference
suppression filter. When combined with a motor cable that is screened and
earthed 360° on both ends, they make it possible to comply with the EMC
limits for conducted interference for all categories and environments
(IEC/EN 61800-3). This requires installation in accordance with EMC
requirements, as well as not exceeding permissible motor cable lengths:
•
1 m for category C1 in the 1st environment,
•
5 m for category C2 in the 1st and 2nd environment,
•
25 m for category C3 in the 2nd environment.
Longer motor cable lengths can be used if additional external radio
interference suppression filters (DX-EMC12…) are used.
￫
For the rated radio interference suppression filters for DC1-S…
variable frequency drives, please refer to
interference suppression filter”, page 93.
￫
The unscreened cable length between the radio interference
suppression filter and the variable frequency drive should not
exceed 300 mm (maximum of 500 mm depending on the setup
inside the metal-enclosed control panel).
