5.2 Cooling
The cooling method in NXL drive is either convection or air cooling with a cooling fan. The cooling
method for lower power ranges (frame MF2 and lower powers of MF3) is a convection type
cooling. Forced air flow cooling is used for frames MF4, MF5, MF6 and higher powers of MF3.
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.
