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 mainte-
nance tasks also require a certain amount of free space.
Make sure that the temperature of the cooling air does not exceed the maximum ambient temperature
of the converter.
