There is provided an organic electronic device including an anode, a hole transport layer, an emissive layer, an electron transport layer, and a cathode. Address space of data files is divided into multiple containers. The contact elements are so designed and so arranged in their associated coupling members, that the contact element of the transmitter-side coupling member is not galvanically connectable with any of the conductor wires of the bus connection cable, but is galvanically connectable with at least one of the conductor wires of the device connection cable. A suction equipment is provided to suck dust containing air through the suction opening of the big container.
