The responsibility for zone classification lies with the plant manager and not the
■
manufacturer/supplier of the equipment.
The plant manager 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.
For the installation of the thermometers, only components (e.g. cables, cable glands,
■
etc.) permitted for "flameproof enclosure" may be used.
For grounding the shields, follow the specifications of IEC/EN 60079-14.
