Siemens SINAMICS G130 Engineering Manual page 507

In the configuration illustrated above, five Cabinet Modules with Motor Modules in Chassis format are connected to a
Basic Line Module. The Line Connection Module and the Auxiliary Power Supply Module are properly rated
according to the configuration. The first transport unit contains the Line Connection Module, the Basic Line Module
plus two Motor Modules. These components require the maximum possible length of a transport unit (2.4 m). A
uniform DC busbar size ordered with option M83 is selected in this unit. In priciple the other Cabinet Modules with a
remaining length of 1.8 m can be installed in another single transport unit. However, the requirement for a separate
auxiliary voltage supply to Motor Module 5 means that a third transport unit is needed. A smaller DC busbar (for
example, M80) may be selected for transport units 2 and 3 as their power requirement is lower.
The parts needed to connect the individual transport units are included in the scope of supply. Please note that no
unified auxiliary voltage supply system can be used when separate auxiliary voltage supply systems are required, as
described in the example above. In this case, the different busbar segments (TE1+2 in the example) must be
separately connected to the Auxiliary Power Supply Module.
Description of Options
Engineering Information
The transport unit is shipped with a crane-hoisting transport
rail which means that option M90 is not required.
