4.3 Parameters for ATEX applications
This section provides useful parameters and information to integrate SARA-R4/N4 series modules in
applications intended for use in areas with potentially explosive atmospheres (ATEX), describing:
Total internal capacitance and inductance of the modules (see Table 25)
Maximum RF output power and voltage at the antenna (ANT) pin of the modules (see Table 26)
☞ Any specific applicable requirement for the implementation of the apparatus integrating the
SARA-R4/N4 series modules, intended for use in potentially explosive atmospheres, must be
fulfilled according to the exact applicable standards: check the detailed requisites on the pertinent
normative for the application, as for example the IEC 60079-0 [12], IEC 60079-11 [13], and
IEC 60079-26 [14] standards.
☞ The certification of the application device that integrates a SARA-R4/N4 series module and the
compliance of the application device with all the applicable certification schemes, directives and
standards required for use in potentially explosive atmospheres are the sole responsibility of the
application device manufacturer.
Table 25 describes the maximum total internal capacitance and the maximum total internal
inductance, considering internal parts tolerance, of the SARA-R4/N4 series modules.

Table 26 describes the maximum RF output power transmitted by SARA-R4/N4 series modules from
the antenna (ANT) pin as Power Class 3 User Equipment for the LTE Cat M1 / NB1 bands and/or as
Power Class 4 Mobile Stations for GSM 850 / E-GSM 900 bands, and the corresponding maximum
root mean square voltage into a 50 system load.

☞ The SARA-R4/N4 series modules do not contain internal blocks that increase the input voltage
(such as step-up, duplicators, or boosters) except for the antenna (ANT) pin, for which the
maximum RF output power and corresponding maximum voltage into a 50 system are shown in
Table 26.
