NOTICE
This parameter is only available for FC 302. It is
not relevant to FC 301 due to different design
and shorter motor cables.
[0] Off
Select [0] Off if the frequency converter is fed by an
isolated mains source (IT mains).
If a filter is used, select [0] Off during charging to
prevent a high leakage current making the RCD switch.
14-50 RFI Filter
Option: Function:
In this mode, the internal RFI filter capacitors between
chassis and the mains RFI filter circuit are cut-out to
reduce the ground capacity currents.
[1] On
Select [1] On to ensure that the frequency converter
complies with EMC standards.

6.2 How to Programme the Active Filter
The factory settings for the filter part of the Low Harmonic Drive are selected for optimal operation with a minimum of
additional programming. All CT-values, as well as frequency, voltage levels and other values directly linked to the frequency
converter configuration are pre-set.
Do not change any other parameters influencing the filter operation. However, selection of read-outs and information
displayed on the LCP status lines can be customised.
To set up the filter, 2 steps are necessary:
1.
Change the nominal voltage in 300-10 Active Filter Nominal Voltage
2. Make sure the filter is in auto mode (press [Auto On])
