COOLING
Enough free space shall be left above and below the frequency converter to ensure sufficient air circulation and cooling.
You will find the required dimensions for free space in the table below.
If several units are mounted above each other the required free space equals C + D. Moreover, the outlet air used for
cooling by the lower unit must be directed away from the air intake of the upper unit.
The amount of cooling air required is indicated below. Also make sure that the temperature of the cooling air does not
exceed the maximum ambient temperature of the converter.
