Electromagnetic
compatibility
The electromagnetic compatibility requirements outlined in the IEC/EN 61326 series for "industrial
environments" are fulfilled when the device is installed in metallic vessel or metallic pipes. Emission
requirements for class B equipment are met. For details, refer to the Declaration of Conformity.
If the device is installed in plastic structures, its function may be influenced by strong
electromagnetic fields. Emission requirements for class A equipment are met (only for use in
"industrial environments").
Reverse polarity protection
Integrated; no damage in the event of reverse polarity or short-circuit
