6.3 EMC-filter
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 don’t have a neutral connected to earth, normally
called IT-net. The BFI can be damaged. 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 can be disconnected by removing a screw on the left side of the BFI. For
BFI IP66 the screw to be removed is located on right side of input terminals L1, L2 and L3 and is
marked “EMC”.
