6 Safety Instructions Safety instructions for harmonic filters 1. PIHF harmonic filter is matched with the frequency converter, which can only be mounted at the power inlet of the frequency converter. 2. The power of the selected filter shall be matched with that of the frequency converter as far as possible, to obtain the best filtering effect.
Guide on Installation and Debugging of Filters 7 Guide on Installation and Debugging of Filters Contents The operating principle and structure of the harmonic filter are briefly described in this chapter. Product overview Wiring diagram The harmonic filter is a low-pass filter that suppresses high-frequency harmonic currents on the input side of the drive.
