IECEx – Certification Scheme for Explosive Atmospheres
For RSP devices labeled with an IECEx certificate number, the following
applies:
List of standards:
IEC 60079-0:2011+Cor.2012+Cor.2013
IEC 60079-15:2010
The equipment shall only be used in an area of not more than pollution
degree 2, as defined in IEC 60664-1.
Make sure that the device has the following label:
Ex nA IIC T4 Gc IECEx DEK 15.0014X
Environmental class and temperature code for RSP types:
T4: 0 °C ≤ Ta ≤ +60 °C for “S“ types or
T4: −40 °C ≤ Ta ≤ +70 °C for “T“ or “E“ types
The modules shall be installed in a suitable enclosure in accordance
with IEC 60079-15 providing a degree of protection of at least IP54
according to IEC 60529, taking into account the environmental
conditions under which the equipment will be used.
When the temperature under rated conditions exceeds 158 °F (70 °C)
at the cable or conduit entry point, or 176 °F (80 °C) at the branching
point of the conductors, the temperature specification of the selected
cable and cable entries shall be in compliance with the actual
measured temperature values.
Provisions shall be made to prevent the rated voltage from being
exceeded by transient disturbances of more than 119 V.
Connectors shall be connected or disconnected exclusively in dead-
voltage state.
The USB port shall remain disconnected.
