3.1 Basic safety notes
5. The wiring shall be given protection against torsional and tensile stresses (e.g. by the use of
conduit).
6. The EPL marking Gb/Ga indicates that the quipment is for use in zone 1, but the sensor

sparks resulting from friction or impact against the enclosure.
3. WARNING – Risk of electrostatic sparking. Clean only with a damp cloth.
4. Group IIIC dust rating is only valid for a maximum dust layer of 5 mm.
5. Temperature code T6 and dust temperature class T
up to 50 °C; Temperature code T5 and dust temperature class T
temperatures between 50 °C and 60 °C.
Hot surfaces resulting from hot process media
Risk of burns resulting from surface temperatures above 65 °C (149 °F).
• Take appropriate protective measures, for example contact protection.
• Make sure that protective measures do not cause the maximum permissible ambient
Exceeded maximum permissible operating pressure
Risk of injury or poisoning.
The maximum permissible operating pressure depends on the device version, pressure limit
and temperature rating. The device can be damaged if the operating pressure is exceeded. Hot,
toxic and corrosive process media could be released.
Ensure that maximum permissible operating pressure of the device is not exceeded. Refer to
the information on the nameplate and/or in Technical specifications (Page 97).
