3.10 Special conditions for safe use (X conditions)

i. The temperature class and permitted maximum ambient temperature, are dependent
upon the options fitted within the equipment and may not be marked on the equipment
label. The user shall refer to this certificate and to the equipment instructions for details of
the applicable temperature class and ambient temperature range.
ii. The user shall consider that heat may be transferred along the measuring instrument and
the equipment shall not exceed the maximum permitted ambient temperature. For further
information, refer to the user instructions.
iii. Models which incorporate a PTFE lining may be marked for use in Group IIB only. The
user shall ensure that such models marked as such are not used in Group IIC Gas nor
Group III dust hazardous areas.
iv. Models which incorporate a PTFE lining may be marked for use in Group IIC gas and
Group IIIB dust hazardous area. Such models also incorporate a warning label advising
the user of a potential electro-static hazard within the process connection area. The user
shall take all necessary precautions to mitigate the risk of electro-static discharge within
the process connection.
v. The equipment may incorporate an integral cable. The user shall ensure that, when
installed, the cable is fixed in place and is protected from mechanical damage.
vi. For Group III applications, under certain extreme circumstances, the non-metallic coating
of the enclosure of this equipment may generate an ignition-capable level of electrostatic
charge. Therefore, the equipment shall not be installed in a location where the external
conditions are conducive to the build-up of electrostatic charge on such surfaces. The
user/installer shall implement precautions to prevent the build-up of electrostatic charge,
e.g. locate the equipment where a charge-generating mechanism (such as wind-blown
dust) is unlikely to be present and clean with a damp cloth.

4. Transport, packaging and storage

4.1 Transport

Check the instrument for any damage that may have been caused by transport.
Obvious damage must be reported immediately.
