Active Front End unit

Enough free space must be left around the Active Front End unit to ensure sufficient air circulation
and cooling. You will find the required dimensions for free space in the Table 21. You will find the
required cooling air, minimum air holes and heat dissipation in the Table 22.
When planning the cooling for the space, take into consideration that the Active Front End unit heat
loss is approx. 2% of the nominal capacity. Air flow, see Figure 34 and Figure 35.
