10. Notes for mounting and operating in hazardous areas
In hazardous areas, only use temperature transmitters that are approved for those
hazardous areas. The approval is marked on the product label.
When connecting them to other devices or component, observe the connection
requirements regarding explosion protection, such as maximum admissible voltage, power
or load with capacitances (see chapter 10.2 “Specific conditions for safe use”).
The following information is based mainly on the EC type examination certificate,
Certification No. BVS 08 ATEX E 019 X.
