5.2.2 LCL filter
Enough free space must be left around the LCL filter to ensure sufficient air circulation and cooling.
You will find the required dimensions for free space in the Table 29. You will find the required cooling
air, minimum air holes and heat dissipation in the Table 30.
When planning the cooling for the space, take into consideration that the LCL filter heat loss is
approx. 1% of the nominal capacity. Air flow, see Figure 34 and Figure 35.
