BFI contains an internal EMC-filter connected to earth. BFI with built-in EMC-filter must never be used
in systems were the 3-phase supplying net doesn’t have a neutral connected to earth, normally called IT-
net. IT-net is normally being used in all types of boats and also some parts of Norway.
In the rest of Europe TN-net is most common were EMC-filter can be used.
The EMC-filter on BFI IP20 and IP66 can be disconnected by removing a screw or screws depending on
drive size. Disconnecting of EMC-filter for BFI-H3 IP55 must be carried out by Beijer Electronics.
