For Use in explosive atmospheres under the European directive 2019/34/EU:
Applied Standards:
EN 60079-0: 2012 + A11: 2013
EN 60079-15: 2010
EN 60079-11: 2012
The Use in Hazardous Locations with explosive atmospheres is only allowed for MS20 or MS30 model
No´s. which are individually labelled
“8 II 3G” and “Ex nA ic IIC T4 Gc” and “DEKRA 13 ATEX 0019X” for MSxx devices,
“8 II 3G” and “Ex nA IIC T4 Gc” and “DEKRA 13 ATEX 0019X” for MB20 devices.
Special conditions for safe use
1. The modules shall be installed in a suitable enclosure in accordance with EN60079-15, taking into
account the environmental conditions under which the equipment will be used.
2. Provisions shall be made to prevent the rated voltage from being exceeded by transient
disturbances of more than 119 V.
3. When the temperature under rated conditions e70 °C at the cable or conduit entry point, or
+80 °C at the branching point of the conductors, the temperature specification of the selected cable
shall be in compliance with the actual measured temperature values.
