4.4.4 Environmental installation conditions
The air is classified by the EN 60721-3-3 standard (Classification of environmental
parameters and their severities – Stationary use at weather-protected locations) based
on climatic and biological conditions as well as on mechanically and chemically active
substances.
Therefore the place of installation must meet specific requirements to ensure
compliance with the conditions for which the UPS was designed.
