The cooling air requirement corresponds at least to that of a free-blowing device. Free-blowing means, that the air inlet and the air outlet
operates unrestricted. With the mounting of the device into a control cabinet it therefore can be necessary to use additional fans, so that
the necessary cooling air requirement is covered. If the necessary cooling air requirement of the power heatsink is not provided, then
the output power of the device has to be reduced.
