Cooling

The drive produces heat in operation and is cooled by air circulated by a fan. Enough free
space needs to be left around the drive to ensure sufficient air circulation and cooling. Different
acts of maintenance also require a 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.
