Basic safety instructions
Manufacturer: Endress+Hauser Wetzer GmbH + Co. KG, Obere Wank 1,D-87484 Nesselwang or www.endress.comRequirements for the personnel‣ Operate the device only if it is in proper technical condition, free from errors
and faults.

‣ The operator is responsible for the interference-free operation of the device.
Hazardous area

The personnel must fulfill the following requirements for its tasks:‣ Trained, qualified specialists must have a relevant qualification for thisspecific function and task.
‣ Are authorized by the plant owner/operator.
‣ Are familiar with federal/national regulations.
‣ Before starting work, read and understand the instructions in the manualand supplementary documentation as well as the certificates (depending on
the application).
‣ Follow instructions and comply with basic conditions.

Intended use
The device is a universal and user-configurable temperature transmitter with
one sensor input for a resistance thermometer (RTD), thermocouples (TC),resistance and voltage transmitters. The head transmitter version of the device isintended for mounting in a terminal head (flat face) as per DIN EN 50446. It isalso possible to mount the device on a DIN rail using the optional DIN rail clip.

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 documentationthat is an integral part of these instructions.
Electromagnetic compatibility
The measuring system complies with the EMC requirements as per the IEC/EN61326 series and NAMUR recommendation NE 21.
NOTICE‣ The device must only be powered by a power unit that operates using anenergy-limited electric circuit according to UL/EN/IEC 61010-1, Section 9.4
and the requirements in Table 18.

If the device is used in a manner not specified by the manufacturer, theprotection provided by the device may be impaired.
