Basic safety instructions

WARNING
Wetted parts unsuitable for the process media
Danger of injury or damage to device.
Hot, toxic and corrosive media could be released if the process medium is unsuitable for the wetted parts.
● Ensure that the material of the device parts wetted by the process medium is suitable for the medium. Refer to the
information in "Technical data" (Page 35).
WARNING
Incorrect material for the diaphragm in Zone 0
Danger of explosion in the hazardous area. In the case of operation with intrinsically safe supply units of category "ib" or
devices of the flameproof enclosure version "Ex d" and simultaneous use in Zone 0, transmitter explosion protection
depends on the tightness of the diaphragm.
● Ensure that the material used for the diaphragm is suitable for the process medium. Refer to the information in the
section "Technical specifications (Page 35)".
WARNING
Unsuitable connecting parts
Danger of injury or poisoning.
In case of improper mounting hot, toxic and corrosive process media could be released at the connections.
● Ensure that connecting parts (such as flange gaskets and bolts) are suitable for connection and process media.
Note
Material compatibility
Siemens can provide you with support concerning selection of sensor components wetted by process media. However, you
are responsible for the selection of components. Siemens accepts no liability for faults or failures resulting from incompatible
materials.
WARNING

The maximum permissible operating pressure depends on the device version. The device can be damaged if the operating
pressure is exceeded. Hot, toxic and corrosive process media could be released.
● Make sure that the device is suitable for the maximum permissible operating pressure of your system. Refer to the
information on the nameplate and/or in "Technical specifications (Page 35)".
WARNING
