Installation MS20/MS30
Release 13 09/2019
For Use in explosive atmospheres under the IECEx Scheme:
Applied Standards: IEC 60079-0:2011 + Corr. 1:2012 + Corr. 2:2013
IEC 60079-15:2010
The Use in Hazardous Locations with explosive atmospheres is only allowed for MS20 or MS30 model
No´s. which are individually labelled
“Ex nA IIC T4 Gc” and “IECEx DEK 14.0078X” for MSxx devices and for MB20 devices
Special conditions for safe use
1. The modules shall be installed in a suitable enclosure in accordance with IEC60079-15, 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 exceeds 70 °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.
4. The equipment shall only be used in an area of not more than pollution degree 2, as defined in
IEC 60664-1.
