Basic Safety Instructions - Siemens SITRANS P DS III Kompaktbetriebsanleitung

WARNING
Use of incorrect device parts in potentially explosive environments
Devices and their associated device parts are either approved for different types of protection or they do not have
explosion protection. There is a danger of explosion if device parts (such as covers) are used for devices with explosion
protection that are not expressly suited for this type of protection. If you do not adhere to these guidelines, the test
certificates and the manufacturer warranty will become null and void.
Use only device parts that have been approved for the respective type of protection in the potentially explosive
•
environment. Covers that are not suited for the "explosion-proof" type of protection are identified as such by a notice
label attached to the inside of the cover with "Not Ex d Not SIL".
Do not swap device parts unless the manufacturer specifically ensures compatibility of these parts.
•
WARNING
Risk of explosion due to electrostatic charge
To prevent the build-up of an electrostatic charge in a hazardous area, the key cover must be closed during operation and
the screws tightened.
The key cover may be opened temporarily at any time for the purposes of operating the pressure transmitter, even during
plant operation; the screws should then be tightened again.

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 36).
WARNING
Incorrect material for the diaphragm in Zone 0
Danger of explosion in the hazardous area. If operated with intrinsically safe supply devices of category "ib" or devices of
the flameproof enclosure version "Ex d" and simultaneous use in Zone 0, pressure 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 36)".
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.
