7.5 Safety device according to EN 50495
The standard EN 50495, which was harmonized within the scope of directive 94/9/EC, formulates requirements for electrical
apparatus that performs one or more safety function(s) in terms of explosion protection. Discretely constructed and complex
safety devices, of which the protective function is controlled via software are evaluated using measures in EN 50595. EN 50495
uses the Safety Integrity Level (SIL) of EN 61508 to define the required safety level for monitoring potential ignition sources.
The requirement of EN 50495:2010 in Appendix E must be observed, which states: If a device contains more than one potential
ignition source, appropriate measures are to be taken for each of these individual ignition sources. Combined apparatus must
conform to the relevant standard EN 60079-0 and/or EN 61241-0 with regard to the category to be achieved.
The JUMO safetyM STB/STW Ex is installed outside of the apparatus in areas that are not potentially explosive. For example, it
monitors the temperature of a warehouse using a probe attached to the apparatus, which is viewed as a potential ignition
source in the apparatus. The probe lines that extend into the potentially explosive area are intrinsically safe and the JUMO
safetyM STB/STW Ex is therefore identified as "associated apparatus" accordingly.
v Chapter 7.2 "Identification markings according to ATEX directive 94/9/EC:"
An increase in the fault tolerance (HFT) and therefore an increase in the device category of the combined apparatus with the
help of the JUMO safetyM STB/STW Ex is only admissable if, other than the ignition risk that is controlled by the JUMO STB/
STW, no other ignition risks are present and the higher device category does not make any additional requirements for the
combined apparatus.
Safety devices for non-electrical apparatus that are included in EN 13463-6 (ignition protection "b") are not covered by EN
50495 (see Chapter 7.6 of this Operating Manual).
