ATEX and IECEx CErTIfICATIoN

ATEX and IECEx CErTIfICATIon DETAIls
The Eagle Quantum Premier Fire and Gas Detection / Releasing System was tested and certified to hazardous

location and combustible gas performance standards. Refer to Figure C-1 for system classification details.

The ATEX/IECEx certified Eagle Quantum Premier System field devices EQ22..., EQ24... and EQ25... are in

compliance with the following standards:
– IEC 60079-0: 2011
– EN 60079-0: 2012
– IEC/EN 60079-1: 2010
– EN 60079-29-1: 2007
– EN 60079-29-4: 2010 (EQ3XXX Only)

The ATEX/IECEx certified Ex n modules of the EQP system are in compliance with the following standards:
– IEC 60079-0: 2011
– EN 60079-0: 2012
– IEC/EN 60079-15: 2010
– EN 60079-29-1: 2007
– EN 60079-29-4: 2010 (EQ3XXX Only)

For all ATEX/IECEx certified Ex n modules in the EQP system, the following Special Conditions for Safe Use apply:

The ambient temperature range is limited for EQ3XXX:

– From –40°C to +70°C if any of the output relays 1-7 (terminals 21-41) is used (energized).

– From –40°C to +80°C if all output relays 1-7 (terminals 21-41) remain open-contacted and de-energized.
For compliance to EN 60079-29-1/-4, the relevant Ex n module must be used with gas detection apparatus that are

certified for compliance to EN60079-29-1/-4 and that provide a suitable linear 4-20 mA output, relay contact output or

LON communication output relative to the %LFL of the available gas in the area of the gas detection apparatus. See

the Manual for details on the required connection parameters.
The EQP Ex n modules shall be used in an area of no more than pollution degree 2 conforming to IEC 60664-1, and

in an enclosure with a tool removable cover that complies with all relevant requirements of IEC/EN 60079-15, rated at

least IP54, and shall be connected to supply circuits where the rated voltage cannot be exceeded by 40% caused by

transient disturbances.
