In the line-up illustrated above, five Chassis Motor Modules are connected to a Basic Line Module. The Line
Connection Module and the Auxiliary Power Supply Module are properly rated for 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 standardized DC link busbar ordered
with option M83 is installed in this unit. Mathematically speaking, the other 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) can be selected
for transport units 2 and 3 as their power requirement may be lower.
The parts needed to connect the individual transport units are included in the scope of supply. Please note that the
auxiliary voltage busbar cannot be connected continuously when a separate auxiliary voltage Infeed is required, as
described for the example above. In this case, the busbar segments (TE1+2 in the example) must be separately
connected to the Auxiliary Power Supply Module.

Engineering Information
The transport unit is shipped with a crane-hoisting transport
rail which means that option M90 is not required.
