3.3.3 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.
