1.9 Four-wire System
All descriptions in the previous sections and following illustrations are targeting 3-wire systems. The filter can also operate in 4-wire
systems. Additional to the steps already described and illustrated, the following must be done:
rd
• A 3 CT must be installed on phase 2/phase B.
• The Neutral wire must be connected to the mains terminal.
• In the PC tool for the filter, adjust the grid topology to 3P4W.
FILTER MALFUNCTION
Connecting the neutral wire in 3-wire applications will cause the filter to work improperly.
-
Do not connect the neutral wire in 3-wire applications.
1.10 Power Losses and Efficiency

1.11 Cable and Fuse Specifications
The filter is protected internally with semiconductor fuses. Branch protection is subject to local installation conditions and regula-
tions, and thus no recommendations can be made. To support selection of suitable branch protection, the internal fuses of the filter
are specified in the following table.
