Altitude 0 to 2000m (0 to 6 560ft) without any restrictions
2000 to 6000m (6 560 to 20 000ft) reduce output power or ambient temperature,
see Fig. 13-2
Altitude de-rating 1.25A/1000m or 5°C/1000m > 2000m (6500ft), see Fig. 13-2
Over-voltage category not applicable The concept of the overvoltage category is
used for equipment energized directly from
the low voltage mains (IEC 60664-1 §4.3.3.2.1).
Degree of pollution 2 EN 62477-1, 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.
