7.
Lead the charging circuit supply cable into the cabinet. 360° grounding of the
cable shield at the entry is recommended to suppress interference (not shown in
the figure).
8.
Twist the cable shield of the charging circuit cable to a bundle and connect to the
cabinet PE (ground) busbar (not shown in the figure). Connect the separate ground
conductors/cables to cabinet PE (ground) busbar.
9.
Connect the phase conductors of the charging circuit supply cable to the charging
circuit. The connections of the ABB-defined charging circuit with the terminal
markings are shown in the example circuit diagrams. For tightening torques, see
the technical data.

Charging circuit wire recommendations
If the charging circuit is needed, the cabinet builder must install and connect it. For
the connections, see the example circuit diagrams.
The charging components are dimensioned according to the DC link capacitances.
For more information on the charging kits, see
DC link capacitance exceeds these limits, the components must be re-dimensioned.
Contact your local ABB representative for more information.
