Instructions specific to hazardous area installations

(Reference European ATEXDirective 94/9/EC, Annex II, 1/0/6)
The following instructions apply to the SITRANS Probe LU covered by certificate number SIRA
06ATEX2355X:
1. For use and assembly, refer to the main instructions.
2. The equipment is certified for use as Category 1G equipment.
3. The equipment may be used with flammable gases and vapors with apparatus groups IIA,
IIB, and IIC, and temperature classes T1, T2, T3, and T4.
4. The equipment is certified for use in an ambient temperature range of –40 C to +80 C.
5. The equipment has not been assessed as a safety related device (as referred to by
Directive 94/9/EC Annex II, clause 1.5).
6. Installation and inspection of this equipment shall be carried out by suitably trained
personnel in accordance with the applicable code of practice (EN 60079-14 and EN 60079-
17 in Europe).
7. Repair of this equipment shall be carried out by suitably trained personnel in accordance
with the applicable code of practice (e.g. EN 60079-19 within Europe).
8. Components to be incorporated into or used as replacements in the equipment shall be
fitted by suitably trained personnel in accordance with the manufacturer's
documentation.
9. It is the responsibility of the user to ensure that manual override is possible in order to
shut down the equipment and protective systems incorporated within automatic
processes which deviate from the intended operating conditions, provided that this does
not compromise safety.
10. The 'X' suffix to the certificate number relates to the following special conditions for safe
use:
Parts of the enclosure may be non-conducting and may generate an ignition-
capable level of electrostatic charge under certain extreme conditions. The
user should ensure that the equipment is not installed in a location where it
may be subjected to external conditions (such as high-pressure steam) which
might cause a build-up of electrostatic charge on non-conducting surfaces.
