2 Basic safety instructions
2.1 Requirements for the personnel
The personnel for installation, commissioning, diagnostics and maintenance must fulfill
the following requirements:
‣Trained, qualified specialists: must have a relevant qualification for this specific
function and task
‣Are authorized by the plant owner/operator
‣Are familiar with federal/national regulations
‣They must have read and understood the instructions in the manual, supplementary
documentation and certificates (depending on the application) prior to starting work
‣Follow instructions and comply with basic conditions
The operating personnel must fulfill the following requirements:
‣Must be suitably trained and authorized by the plant operator to meet the
requirements of the task
‣Follow the instructions in this manual
2.2 Intended use
The device is a universal and user-configurable temperature transmitter with one sensor
input for resistance thermometers (RTD), thermocouples (TC), resistance and voltage
transmitters. The head transmitter version of the device is intended for mounting in a
terminal head (flat face) as per DIN EN 50446. It is also possible to mount the device on a
DIN rail using the optional DIN rail clip. The device is also optionally available in a version
suitable for DIN rail mounting as per IEC 60715 (TH35).
If the device is used in a manner not specified by the manufacturer, the protection
provided by the device may be impaired.
The manufacturer is not liable for damage caused by improper or non-intended use.
2.3 Operational safety
‣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
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.
Electromagnetic compatibility
The measuring system complies with the general safety requirements as per EN 61010-1,
the EMC requirements as per the IEC/EN 61326 series and the NAMUR recommendations
NE 21.
NOTICE
‣The device must only be powered by a power unit that operates using an energy-limited
electric circuit according to UL/EN/IEC 61010-1, Section 9.4 and the requirements in
Table 18.

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?
3.2 Nameplate
The right device?
Compare and check the data on the nameplate of the device against the requirements of
the measuring point:
