COOLING
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. Some free space
is also necessary for maintenance.
If many AC drives are installed above each other, the necessary free space is C + D (see Fig.
15 Installation space). You must also make sure that the outlet air from the lower drive goes
to a different direction than the air intake of the top 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.
