NOTE!
It is important that all the flexible braids have the same length (defined by dimension "E"), which will
depend on the panel construction.

3.4.9 Input Filters

3.4.9.1 Basic Definitions

For the operation of the regenerative frequency converter, it is necessary to use an input filter to eliminate the
circulation of high frequency currents generated by the switching of the regenerative frequency converter IGBTs
on the power grid. In this manual, input filters are the components connected between the power grid and the
regenerative frequency converter input.

3.4.9.2 How to Specify the Filter Model

WEG has input filters ready to be used with each of its regenerative frequency converters. To specify the model of
the input filter, enter the voltage and current values into the respective smart code fields for rated supply voltage
and rated input current, as in the example of
