The connection of a thermocouple sensor to the TIFxx must be made with a
screened cable. The shield must be electrically connected with the housing of
the grounded thermometer and, additionally, grounded to the side of the TIFxx.
It should be ensured that there is equipotential bonding on installation, so that
no balancing current can flow via the shield. Here, in particular, the installation
regulations for hazardous areas should be followed!
