Environmental conditions Note: For use in Pollution Degree 2 and Overvoltage Category II environments only. Only non-conductive contaminants are permitted (e.g., dust). If contamination is more severe, install the device in a suitable enclosure or control cabinet. Direct feed-in from the building's electrical system and higher overvoltage categories are not allowed.
