4.7 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 of IP20 and IP66 are disconnected according to the pictures below. Remove the
screw/screws marked “EMC”, see arrows in the picture below.

By adjusting the parameter settings, the drive can be configured for multiple applications and not just
for Forward or Reverse. This could typically be for Hand/Off/Auto applications (also known and
Local/Remote) for HVAC and pumping industries.
