Markings:
See
Table 5-1
Special Conditions for Safe Use (X):
1. See certificate for ambient temperature range.
2. The non-metallic label may store an electrostatic charge and become
a source of ignition in Group III environments.
3. Guard the LCD display cover against impact energies greater than 4
joules.
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
