Abstract: A field of electric drive devices, such as electric drive devices for industrial applications, and automation devices within electric drive device installations, and more particularly to an automation device for an electric drive device and an electric drive device. The automation device according to the present invention, is arranged for an electric drive device, in which an enclosure of the automation device includes an at least one cockled side face including a multitude of curved heat sink fins along the cockled side face extending from a first end side of the automation device to a second end side of the automation device, the first end side and the second end side being neighboring end sides, the first end side joining the second end side. With the help of the solution according to the present invention, airflow in an electric drive device cabinet installation is directed to areas, where airflow is otherwise blocked.
