How to Install

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 and L3 must be connected to the filters terminals X2.1,
X2.2 and X2.3
