Self-assembling bus
In the self-assembling bus, all modules are lined up on the mounting rail. For this purpose
the modules are hung in the upper area, with inserted U connectors, and are pivoted
downward and fastened in the lower area by means of screws.
During the pivoting in, the modules are connected to each other with the U connector. The U
connector provides the mechanical and electrical connection between the modules.
