8 Endress+Hauser
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 must 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
applicable: are the Safety Instructions (e.g. XA) for hazardous areas provided?
If one of these conditions is not satisfied, contact your Sales Center.
