Cooling
The drives produce heat in operation and are cooled down by air circulated by a fan. Enough
free space shall therefore be left around the drive to ensure sufficient air circulation and cooling.
Different acts of maintenance also require certain amount of free space.
Make sure that the temperature of the cooling air does not exceed the maximum ambient tem-
perature of the converter.
