5. Heat dissipation

The heat dissipation (=self-warming) of all installed electrical load (e.g. transformers, relays, semiconductors, bus bars, etc.) has to be taken into account if components are operated continuously.

6. Climate

to maintain a minimum temperature inside of the enclosure and to avoid low temperatures

Lowest ambient temperature		°C
Desired minimum temperature inside of the enclosure		°C
(lowest temperature inside of enclosure to ensure all equipment inside of the enclosure will work properly)
Temperature difference		K

to maintain a specific humidity level in an enclosure to avoid condensation

Highest ambient temperature		°C
Highest ambient humidity (RH)		%
Desired humidity inside of enclosure (RH) (max. 65% recommended)		%
Height (above sea level) max. 2000 m or max. 6500 f		m
