‣The operator is responsible for ensuring trouble-free operation of the device.
Hazardous area
To eliminate a danger for persons or for the facility when the device is used in the hazardous
area (e.g. explosion protection or safety equipment):
‣Based on the technical data on the nameplate, check whether the ordered device is
permitted for the intended use in the hazardous area. The nameplate can be found on the
side of the transmitter housing.
‣Observe the specifications in the separate supplementary documentation that is an integral
part of these instructions.

Instructions. The device is equipped with security mechanisms to protect it against any
inadvertent changes to the settings.
Incoming acceptance and product identification iTEMP TMT86
6 Endress+Hauser
IT security measures, which provide additional protection for the device and associated data
transfer, must be implemented by the operators themselves in line with their security
standards.
3 Incoming acceptance and product identification
3.1 Incoming acceptance
1. Unpack the temperature transmitter carefully. Are the contents or packaging
undamaged?
Do not install damaged components, as otherwise the manufacturer cannot
guarantee the material resistance or ensure compliance with the original safety
requirements, and therefore cannot 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 order 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 met, please contact the manufacturer's sales office.
3.2 Product identification
The following options are available for identification of the device:
• Nameplate specifications
• Extended order code with breakdown of the device features on the delivery note
• Enter the serial number from the nameplate in the W@M Device Viewer
(www.endress.com/deviceviewer): all data relating to the device and an overview of the
Technical Documentation supplied with the device are displayed.
• Enter the serial number on the nameplate into the Endress+Hauser Operations App or scan
the 2-D matrix code (QR code) on the nameplate with the Endress+Hauser Operations App:
all the information about the device and the technical documentation pertaining to the
device is displayed.
Approval in hazardous areas: Ensure that the information on the nameplate matches the
enclosed Ex documentation (XA...).
