5.2 Cooling Requirements
5.2.1 General Cooling Requirements
The AC drive produces heat in operation. The fan moves air and decreases the temperature of the drive. Make sure that there is
sufficiently free space around the drive.
Make sure that the temperature of the cooling air does not go above the maximum ambient operating temperature or below the
minimum ambient operating temperature of the drive.
5.2.2 Cooling of FR4 to FR9
If many AC drives are installed above each other, the necessary free space is C + D (see
). Make also sure that the outlet
air from the lower drive goes to a different direction than the air intake of the top drive.
