Markings
Specific Conditions of 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
four 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
Sensor probe does not exceed 266 °F (130 °C).
7. Non-standard paint options may cause risk of 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.

Special Conditions for Safe Use (X):
1. When fitted with the transient terminal options, the equipment is
not capable of passing the 500 V insulation test. This must be taken
into account during installation.
2. The enclosure may be made from aluminum alloy with a protective
polyurethane paint finish; however, care should be taken to protect it
from impact or abrasion when located in Zone 0.
