Note
The distance between the discharge opening of the air conditioning unit and the electronic
equipment must be at least 200 mm.
Note
If the components are installed in a sealed control cabinet, you must use internal air cooling that
ensures an unobstructed airflow to prevent local hotspots. It is best to mount the fan above the
components to optimize the air flow (air is drawn in).
