------ LCL filters: Instructions Manual ----- Page 4

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).
