4.12 SARA-G3 / SARA-U2 ATEX modules conformance for use in
explosive atmospheres
SARA-G340 ATEX, SARA-G350 ATEX, SARA-U201 ATEX and SARA-U270 ATEX modules are certified as
components intended for use in potentially explosive atmospheres compliant to the following standards:
 IEC 60079-0: 2011
 IEC 60079-11: 2011
 IEC 60079-26: 2006
The certification numbers of the modules, according to the ATEX directive 2014/34/EU, are:
 SIQ 13 ATEX 032 U for SARA-G340 ATEX and SARA-G350 ATEX
 SIQ 16 ATEX 298 U for SARA-U201 ATEX
 SIQ 15 ATEX 017 U for SARA-U270 ATEX
The certification numbers of the modules, according to the IECEx conformity assessment system, are:
 IECEx SIQ 13.0004U for SARA-G340 ATEX and SARA-G350 ATEX
 IECEx SIQ 16.0006U for SARA-U201 ATEX
 IECEx SIQ 15.0001U for SARA-U270 ATEX
According to the standards listed above, SARA-G340 ATEX, SARA-G350 ATEX, SARA-U201 ATEX and
SARA-U270 ATEX modules are certified with the following marking:
 SARA-G340 ATEX, SARA-G350 ATEX and SARA-U270 ATEX: Ex II 1G, Ex ia IIC/IIB
 SARA-U201 ATEX: Ex II 1G, Ex ia IIB
The temperature range for using SARA-G340 ATEX, SARA-G350 ATEX, SARA-U201 ATEX and SARA-U270 ATEX
modules is defined in the ‘Operating temperature range’ section of the SARA-G3 series Data Sheet [1] and the
SARA-U2 series Data Sheet [2] respectively.
All these modules are suitable for temperature class T4 applications, as long as the maximum input power does
not exceed 2.5 W on SARA-G340 ATEX and SARA-G350 ATEX, or 3.5 W on SARA-U201 ATEX and SARA-U270
ATEX modules.
The RF radiating profile of SARA-G340 ATEX, SARA-G350 ATEX, SARA-U201 ATEX and SARA-U270 ATEX
modules is compliant to all the applicable 3GPP / ETSI standards, with a maximum of 2 W RF pulse power and
1.15 mJ RF pulse energy according to the GSM/GPRS power class stated in Table 2; the maximum average power
of SARA-U201 ATEX and SARA-U270 ATEX, according to the WCDMA power class stated in Table 2, is
250 mW.
The nameplate of SARA-G340 ATEX, SARA-G350 ATEX, SARA-U201 ATEX and SARA-U270 modules is described
in the ‘Product labeling’ section of the SARA-G3 series Data Sheet [1] and the SARA-U2 series Data Sheet [2].
Table 65 lists the maximum input and equivalent parameters that must be considered in sub-division IIC for
SARA-G340 ATEX, SARA-G350 ATEX, SARA-U201 ATEX and SARA-U270 ATEX.
