WARNING!!!: Due to the LCL filter performance mode, it is quite likely to find elevate harmonic
distortion levels of voltage at the input of the speed drive (downstream to the filter output reactor (L2)).
This voltage distortion should cause no malfunction of the speed drive to be filtered, but it is very much
recommendable, in case that this power drive is taken the auxiliary voltage supply of the control
system from the input of the drive, to take this auxiliary supply from the LCL input, that is, upstream to
the filter input reactor (L1).
