The responsibility for classification of zones lies with the plant
■
operator and not the manufacturer/supplier of the equipment.
The plant operator guarantees, and is solely responsible, that all
■
thermometers in use are identifiable with respect to all safety-relevant
characteristics. Damaged thermometers may not be used.
Electrical screening may only be grounded at one end, and outside of
■
the Ex area. Special cases are described in DIN EN 60079-14:2003.
There must be a galvanic separation between the intrinsically safe
■
and the non-intrinsically safe electrical circuits.
