It is recommended that the guides relating to the installation, use, and
maintenance of flammable gas and oxygen detectors (standard EN/IEC 60079-
29-2) and toxic gas detectors (standard EN 45544-4) should be clearly
understood.
Installation shall be in accordance with the standards in force, classification of the
zone, and in conformity with standards EN/IEC 60079-14 and EN/IEC 61241-14,
the editions in force, or with other national and/or local standards.

Regulations and conditions of use
❧
The installation should meet all the regulations currently in force for
installations in explosive atmospheres, in particular the standards
IEC/EN 60079-14 and IEC/EN 60079-17 (whichever editions are in force)
or in accordance with other national standards.
❧
Generally speaking, the ambient temperature, supply voltage, and power
that are mentioned in this document relate to explosion safety. This has
nothing to do with the operating temperatures of the detector.
❧
The instrument is authorized for use in zones 1, 2, 21, and 22 at ambient
temperatures varying from -50°C to + 70°C.
❧
The detector sensor in the transmitter should always be in contact with the
ambient air. Therefore:
- Do not cover the detector.
- Do not paint the detector.
- Avoid dust.
