4.9 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 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 can be disconnected by removing a screw or screws depending on drive size.
Disconnecting of EMC-filter for BFI-P2 IP55 and IP66 must be carried out by Beijer Electronics.

4.10 IP66 Integrated Control Switch and Potentiometer Wiring
BFI-P2 is optionally available with an integrated mains disconnect / isolator and front mounted control
switch and potentiometer. This allows the drive to be operated directly from the front control panel,
whilst also providing for options such as Hand / Auto or Local / Remote Control etc.
The built-in switch and potentiometer are wired inside the terminal cover directly to the user control
terminals as shown in the diagram below.
These connections may be disconnected by the user if they are not required.
Switch Left: Run Reverse with speed decided by potentiometer.
Switch Centre: Stop.
Switch Right: Run Forward with speed decided by potentiometer.
