Installation

Please read the guidelines on the installation, use and maintenance of detectors for
detection of flammable gases and oxygen (standard EN/IEC 60079-29-2) and toxic
gases (standard EN 45544-4).

2.1 Regulations and conditions of use

• The installation will be done according to current standards for installation in explosive
areas especially regulations IEC/EN 60079-14 and IEC/EN 60079-17 (current
editions) or according to other national standards.
• The equipment is authorized for use in Zones 1, 2, 21 and 22 and is certified for ambient
temperatures from -20 °C to + 60 °C. Note that this is not the operating temperature
which, by the way, is sensor dependent.
• Regarding the OLCT 60D-id version, the remote sensor can be used in zones 0, 1, 2, 20,
21 and 22. The transmitter itself is for use in zones 1, 2, 21 and 22 only.
• The detector must always be in contact with the ambient air. Thus:
- Do not cover the sensor,
- Do not paint the sensor,
- Avoid dust deposits.

2.2 Necessary equipment

• Complete detector assembly
• Cable
• Tools
• Fixing hardware
• Multimeter (intrinsically safe certified when needed)

2.3 Location of the detector

Depending on the density of the gas to be detected or the application, the detector shall be
positioned at ground level, or on the ceiling at the same height as the airflow, or near air
extraction ducts. Heavy gases may be detected at the ground level, while light gases will be found
at ceiling height. Gas densities are found on page 30.
