System structure

Line Modules are coupled with the various Motor Modules using prefabricated DC busbar
sets with different current load ratings.
All standard busbars, as well as electronics components, are protected against
environmental effects. This is achieved through the use of nickel-plated copper bars and
coated modules throughout.
An auxiliary power supply system for the individual Cabinet Modules supplies the auxiliary
power required for the heat exchanger fans and the 24 V DC loads.
Communication between the Control Unit, Line Module and Motor Module, and other active
SINAMICS components takes place via DRIVE-CLiQ connections.
DRIVE-CLiQ is an internal serial interface of the drive that enables fast and easy
configuration of the complete drive line-up with prefabricated cables in varying lengths.
As an option, Cabinet Modules can be delivered in preconfigured transport units with a total
width of up to 2,400 mm each. Transport units enable the various devices to be quickly and
easily assembled on-site.
