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 23. You will find the required
cooling air, minimum air holes and heat dissipation in the Table 24.
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 37 and Figure 38.
