1 About this document
1.1 Safety Instructions (XA)
When using in hazardous areas, compliance with national regulations is mandatory. Separate
Ex-specific documentation is provided for measuring systems that are used in hazardous
areas. This documentation is an integral part of these Operating Instructions. The installation
specifications, connection data and safety instructions it contains must be strictly observed!
Make sure that you use the right Ex-specific documentation for the right device with approval
for use in hazardous areas! The number of the specific Ex documentation (XA...) is provided
on the nameplate. If the two numbers (on the Ex documentation and the nameplate) are
identical, then you may use this Ex-specific documentation.

3 Incoming acceptance and product identification
3.1 Incoming acceptance
1. Unpack the temperature transmitter carefully. Is the packaging or content free from
damage?
 Damaged components may not be installed as the manufacturer can otherwise not
guarantee compliance with the original safety requirements or the material
resistance, and can therefore not be held responsible for any resulting damage.
2. Is the delivery complete or is anything missing? Check the scope of delivery against your
order.
3. Does the nameplate match the ordering information on the delivery note?
4. Are the technical documentation and all other necessary documents provided? If
