3.3.6 Cooling
1)
Air temperature in the entire intake area of the device.
2)
The cooling air requirement corresponds to at least that of a freely-blowing device. Freely-blowing means that the air flow in and out are
unobstructed. Therefore, when installing the device in a control cabinet, it could be necessary to make use of additional fans in order
that the necessary cooling air requirement is covered. If the necessary cooling air requirement of the passive cooling unit is not provided
for, then the output power of the device must be reduced.
