4. Flameproof joints are not intended for repair.
5. A suitable certified Ex d or Ex tb enclosure is required to be connected
to temperature probes with Enclosure option “N”.
6. Care shall be taken by the end user to ensure that the external
surface temperature on the equipment and the neck of DIN Style
Sensor probe does not exceed 130 °C.
7. Non-Standard Paint options may cause risk from electrostatic
discharge. Avoid installations that cause electrostatic build-up on
painted surfaces, and only clean the painted surfaces with a damp
cloth. If paint is ordered through a special option code, contact the
manufacturer for more information.
