15. ELECTRICAL DATA AT MAXIMUM CONDITIONS ALLOWED (FULL LOAD)
Give the typical operating conditions of units designed for outdoor installation, which can be associated (according to reference docu-
ment IEC 60721) to the following classes:
- climatic conditions class 4K4H: air temperature range from -20 up to 55°C (*), relative humidity range from 4 up to 100%, with possible
precipitations, at air pressure from 70 and 106 kPa and a maximum solar radiation of 1120 W/m
2
- special climatic conditions negligible
- biological conditions class 4B1 and 4C2: locations in a generic urban area
- mechanically active substances class 4S2: locations in areas with sand or dust representative of urban areas
- mechanical conditions class 4M1: locations protected from significant vibrations or shocks
The required protection level for safe operation, according to reference document IEC 60529, is IP43XW (protection against access, to
the most critical unit's parts, of external devices with diameter larger than 1 mm and rain).
The unit can be considered IP44XW protected, i.e. protected against access of external devices (with diameter larger than 1 mm) and
water in general.
(*) for the unit’s operating limits, see “selection limits” section
