Altitude 0 to 6000m (0 to 20 000ft) reduce output power or ambient temperature
above 2000m sea level.
Altitude de-rating 6W/1000m or 5°C/1000m above 2000m (6500ft), see Fig. 13-2
Over-voltage category III IEC 62477-1, EN 50178, altitudes up to 2000m
II altitudes from 2000m to 6000m
Degree of pollution 2 IEC 62477-1, EN 50178, not conductive
LABS compatibility The unit does not release any silicone or other LABS-critical substances and is suitable for
use in paint shops.
*) Operational temperature is the same as the ambient temperature and is defined as the air temperature 2cm below the unit.
**) Do not energize while condensation is present
***) Tested in combination with DIN-Rails according to EN 60715 with a height of 15mm and a thickness of 1.3mm and standard mounting
orientation.
