The certification of the application device that integrates a SARA-N211 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.
The application device integrating a SARA-N211 module for use in potentially explosive atmospheres
must be designed so that any circuit/part of the apparatus shall not invalidate the specific
characteristics of the type of protection of the module.
The intrinsic safety “i” type of protection of SARA-N211 modules is based on the restriction of the
electrical energy within equipment and of the interconnecting wiring exposed to the explosive
atmosphere to a level below that which can cause ignition by either sparking or heating effects.
The following input and equivalent parameters must be considered integrating a SARA-N211 module
in an application device intended for use in potentially explosive atmospheres:
Total internal capacitance, Ci (see
Total internal inductance, Li (see
The module does not contain blocks which increase the voltage (e.g. like step-up, duplicators,
boosters, etc.)
The nameplate of SARA-N211 modules is described in the “Product labeling” section of the SARA-N2
series Data Sheet
. For additional info and modules’ certificate of compliancy for use in potentially
explosive atmospheres, see our website (
) or contact the u-blox office or sales
representative nearest you.

The final enclosure of the application device integrating SARA-N211 modules, intended for use in
potentially explosive atmospheres, must guarantee a minimum degree of ingress protection of
IP20.
