6.2.1 ATEX certification

SARA-N211 modules are certified as components intended for use in potentially explosive

atmospheres compliant to the following standards:



IEC 60079-0



IEC 60079-11



IEC 60079-26

SARA-N211 modules certification number according to the ATEX directive 2014/34/EU:



SIQ 18 ATEX 104 U

SARA-N211 modules certification number according to the IECEx conformity assessment system:



IECEx SIQ 18.0004U

According to the standards listed above, SARA-N211 modules are certified with following marking:



Ex II 1G, Ex ia IIC

According to the marking stated above, the modules are certified as electrical equipment of:



group ‘II’: intended for use in areas with explosive gas atmosphere other than mines susceptible

to firedamp



category ‘1G’: intended for use in zone 0 hazardous areas, in which explosive atmospheres caused

by mixtures of air and gases, vapors or mists are present continuously, for long periods or

frequently



level of protection ‘ia’: intrinsically safe apparatus with very high level of protection, not capable

of causing ignition in normal operation and with the application of one countable fault or a

combination of any two countable fault plus those non-countable faults which give the most

onerous condition



subdivision ‘IIC’: intended for use in areas where the nature of the explosive gas atmosphere is

considered very dangerous based on the Maximum Experimental Safe Gap or the Minimum

Ignition Current ratio of the explosive gas atmosphere in which the equipment may be installed

(a typical gas is hydrogen), so that the modules are also suitable for applications intended for use

in subdivision IIB (typical gas is ethylene) and subdivision IIA (a typical gas is propane)

Section 4.2.1 defines the temperature range of use for SARA-N211 modules.

The RF radiating profile of SARA-N211 modules is compliant to all the applicable 3GPP / ETSI

standards, with a maximum of 250 mW RF average power according to the LTE Cat NB1 Power Class

stated in Table 2. Section 8.1 describes the nameplate of SARA-N211 modules (see Figure 8).

Table 21 lists the maximum input and equivalent parameters that must be considered in the sub-

division IIC, the sub-division IIB and the sub-division IIA for SARA-N211 modules.
