A method of arranging frequency converters in a cabinet including placing the frequency converters one above the other in a first section of the cabinet, and passing a cooled medium from a second section to a third section of the cabinet such that the cooled medium flows substantially across parts included in the respective frequency converters. Further, the second and third sections are on adjacent sides of the first section. The method also includes arranging supply voltage and load cabling connected to the frequency converters in at least one of the second or third sections of the cabinet.
