Use of grounded thermocouples

 WARNING

Grounding and shielding

Although it is basically possible to use grounded thermocouples with an ELX331x, maintaining explosion
protection requires separate consideration of the grounding concept, the number of grounded thermocou-
ples and the type of grounding and shielding. The requirements of IEC 60079-11, IEC 60079-14 and
IEC 60079-25 as well as other standards and regulations must be observed.

For grounded thermocouples use only one ELX331x per ELX9560

If grounded thermocouples are used, measurement errors may occur when using several ELX331x
behind one ELX9560. It is recommended to use only one ELX331x per ELX9560 if the use of
grounded thermocouples is intended.
