Safety Instructions For Hazardous Area Installation - Prosense PQ Series Installation And User Manual

SAFETY INSTRUCTIONS FOR HAZARDOUS AREA INSTALLATION

Prosense PQ series gas detectors are projected and built according to ATEX Directive
2014/34/EU with reference to standard EN 60079-0, EN 60079-1, EN 60079-29-1. "ATEX", by
the French "ATmosphere EXplosible", provides the technical requirements to be applied to
equipment intended for use in potentially explosive atmospheres. The scope of directive is to
remove technical barriers to trade between Member States of the European Community. The
Prosense PQ series gas detectors must be installed and maintenance according to the suitable
standards for electrical application in potentially explosive atmospheres (example: EN 60079-
14, EN 60079-17 or other national standards).
Read this instruction first and keep this instruction manual always available.
The following instructions apply to equipment covered by ATEX certificate number:
1. Prosense PQ series gas detectors may be installed in hazardous area with flammable gases,
vapours, and mist, group II, category 2G, maximum superficial permissible temperature 70°C.
Device category 2G, Identification II 2G
Ex db IIC T6 Gb (Tamb = -40°C : +70°C) – For explosion protection
(Tamb = -20°C : +60°C) – For performance
It means: (European Community logo for ATEX applications) – group II (potentially
explosive atmospheres – surface application – OTHER than mines)
Category 2G ( G => Gas ) – Zone 1 and Zone 2
Ex db => protection mode: explosion proof enclosure
IIC => define kind of gases
T6 => Temperature class -- Maximum allowable surface temperature.
IP 65 => Mechanical protection degree – protection against solid, dust and liquid.
2. Suitably trained personnel shall carry out installation in accordance with applicable code
practice.
3. The electrical devices must be grounded using their grounding connections. The grounding
connection must be ATEX certified, suitable for the application required, substances,
maximum superficial temperature, and ambient temperature.
4. The user should guarantee periodical cleaning of the places were dust can storage to avoid
the paling up to 5 mm.
5. The user should not repair this equipment.
6. The user should guarantee the keeping of the safety characteristic of the device after
maintenance of repairing.
