The following optional DC busbars are available:
● Option M80 = busbar system 1 x 60 x 10
● Option M81 = busbar system 1 x 80 x 10
● Option M82 = busbar system 1 x 100 x 10

● Option M84 = busbar system 2 x 80 x 10
● Option M85 = busbar system 2 x 100 x 10
● Option M86 = busbar system 3 x 80 x 10
● Option M87 = busbar system 3 x 100 x 10
Note
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.
