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.
