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
