ATEX directive 94/9/EG – specific regulations for safe
operation
Relevant for RS20/22/30/32/40 devices when operating in explosive gas
atmospheres according to ATEX Directive 94/9 EC, the following applies:
List of standards:
EN 60079-0:2012 + A11:2013
EN 60079-15:2010
Certificate No.: DEKRA 11ATEX0139 X or KEMA 09ATEX0067 X.
Make sure that the device has the following label:
II 3G Ex nA IIC T4 Gc DEKRA 11ATEX0139 X
for RS20/22/30/32 types.
II 3G Ex nA IIC T3 ... T4 Gc KEMA 09ATEX0067 X
for RS40 types.
Ambient rating and temperature code for RS20 and RS30 types:
T4: 0 °C ≤ Ta ≤ +60 °C for “S” types
(item 14 of nomenclature breakdown) or
T4: −40 °C ≤ Ta ≤ +70 °C for “T” or “E” types
(item 14 of nomenclature breakdown).
Ambient rating and temperature code for RS22 and RS32 types:
T4: −40 °C ≤ Ta ≤ +50 °C for “T” or “E” types
(item 14 of nomenclature breakdown) or
T4: 0 °C ≤ Ta ≤ +50 °C for “S” types
(item 14 of nomenclature breakdown)
Ambient rating and temperature code for RS40 types:
T3: −40 °C ≤ Ta ≤ +70 °C for “T” or “E” types
(item 14 of nomenclature breakdown).
T4: −40 °C ≤ Ta ≤ +60 °Cfor “T” or “E” types
(item 14 of nomenclature breakdown).
T4: 0 °C ≤ Ta ≤ +60 °C for “S” types
(item 14 of nomenclature breakdown).
The modules shall be installed in a suitable enclosure in accordance
with EN 60079-15 providing a degree of protection of at least IP54
according to EN 60529, taking into account the environmental
conditions under which the equipment will be used.
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 and
cable entries shall be in compliance with the actual measured
temperature values.
