The MX15 detection central unit, designed for measurement of explosive gas, is compliant
with the requirements of the ATEX 94/9/CE European Directive regarding explosive atmospheres.
Thanks to its metrological performance, the MX15 central unit associated with the
INDUSTRIAL SCIENTIFIC CEX300 and OLC 10 detectors is a safety device for ATEX Zone 2
classified areas. The central unit can also reduce the risk of explosion through information provided
to external units.
The site manager where the equipment is installed should take into consideration and
comply with the information in the following paragraphs. Refer to the provisions of the ATEX
1999/92/CE European Directive regarding the enhancement of safety and health of the workers
exposed to risks of explosive atmospheres.

Installation will be performed in accordance with existing standards, in particular, EN
60079-14, EN 60079-17 standards.
The MX15 central unit should not be exposed to mechanical vibrations and should be
installed in a safe area, away from explosive atmospheres.
It is essential to refer to the operating and start-up instructions of the above-mentioned gas
detectors in paragraph ‘Detail specifications for use in explosive atmospheres in accordance with the
ATEX 94/9/CE European Directive.’
