About this manual What this chapter contains The chapter describes the target audience and safety in short. Target audience The manual is intended for people who select, plan the installation, install, commission and use the du/dt filter. Read the manual before working on the filter. The reader is expected to know the fundamentals of electricity, wiring, electrical components and electrical schematic symbols.
Operation principle What this chapter contains The chapter describes the operation of the du/dt filter and the intended use. Operation principle The drive employs modern IGBT inverter technology. Regardless of frequency, the drive output comprises pulses of approximately the drive DC bus voltage with a very short rise time.
(U The values in the first graph are measured with an ABB du/dt filter while the second graph without any output filtering. The values in the second graph are only representative.
For the ACS800 drives, the data can be found either from the appropriate Technical catalog or Hardware manual. The PDF files are available at www.abb.com/drives. Applicability checks of the pre-selected filter Long or several parallel motor cables, or special cable types may cause excessive temperature rise in the filter.
Maximum current and heat dissipation capacity of the filter The maximum current (I ) and heat dissipation capacity (E ) of the filter are given in the table below. 400 V 500 V 690 V Du/dt filter type / mJ loss NOCH0016-60/2 NOCH0016-65...
Installation What this chapter contains This chapter contains general note and restrictions to be considered in the installation, and shows the connections diagrams. General notes and restrictions WARNING! Do not attempt any work on a powered drive. After switching off the mains, always allow the intermediate circuit capacitors 5 minutes to discharge before working on the frequency converter, the motor or the motor cable.
