6.2.3 Wiring
Supply voltage must be connected to the terminals X1.1, X1.2 and X1.3. The frequency converter supply terminals L1, L2 and L3
must be connected to the filter terminals X2.1, X2.2 and X2.3
Paralleling of frequency converters
If several frequency converters are to be connected to one harmonic filter, the connection method is similar to the connection
described above. The supply terminals L1, L2 and L3 of the frequency converters must be connected to the filter terminals X2.1,
X2.2 and X2.3.
NOTE
Use cables complying with local regulations.
Paralleling of filters
If the mains input current of the frequency converter exceeds the nominal current of the largest harmonic filter, several
harmonic filters can be paralleled to achieve the necessary current rating – see
Electrical Data
tabels.
Supply voltage be connected to the terminals X1.1, X1.2 and X1.3 of the filters. The frequency converter supply terminals L1, L2
