This Technical Note provides information about a problem with the RFI filter B84143-A600-S9 (10025451) and the corrective actions required to avoid personal injury.
The ABB B84143-A600-S9 RFI filter is installed at the input of SAMI STAR and ACS 600 frequency converters to limit conducted emissions. It contains chokes and capacitors connected between phases, the virtual star point, and ground. The filter has been used as an optional component in several SAMI STAR and ACS600 models.
The note reports deformation and possible explosion of filters manufactured between 1996‑2000 due to defective capacitors. It advises immediate removal of any deformed filter and states that the frequency converter can operate safely without the filter. Replacement with a new Epcos RFI filter requires engineering assessment and verification of network requirements.
Yes, running the frequency converter without the RFI filter is not harmful.
