Siemens SINAMICS S120 Manual page 398

Options
9.42 M80 to M87, DC busbar system
Note
Current rating of the DC busbar
The required current intensity of the DC busbar depends on the individual plant
configuration. For this reason, a fixed DC busbar thickness is not assigned to the individual
Cabinet Modules. The required thickness must be configured for each individual case and
specified as option M80 to M87 (mandatory option).
For transport units, integrated busbars are installed at the factory. Connection jumpers are
not required inside a transport unit.
For option M26 (side panel on the right), connection jumpers are not required, nor are they
permitted.
