3.10 Cooling requirement
It must be ensured that the environmental temperature is kept below 40°C with appropriate thermal
management (e.g. cabinet cooling). Filter operation in environments with higher temperatures require
a temperature derating.
External air flow is required in all configurations. The minimum air flow required for all filters can be
found in Table 25. It is recommended to have the active cooling fans located at the top of the cabinet
and air inlet located according to Figure 5 and Table 26.

*External air flow required for filter configurations without embedded ventilation.
Recommended installation on top of cabinet
Note: The required inlet air flow must be provided to guarantee normal operation of the filter.
Insufficient inlet air flow or blocking of air channel might cause overheating of filter compo-
nents.
All ecosine max passive harmonic filters have been tested and qualified with cabinet design, presented
in the following. The fan configuration below is recommended, however not mandatory if the inlet air
flow can be ensured otherwise.
