Qualified personne l for hazardous area applications
WARNING
Unsuitable devic e for the hazardous area
This device left the factory in good working condition. In order to maintain this status and to
ensure safe operation of the device, observe these instructions and all the specifications
relevant to safety.
Observe the information and symbols on the device. Do not remove any information or
symbols from the device. Always keep the information and symbols in a completely legible
state.
Danger to personnel, system and environment can result from modifications to the device,
particularly in hazardous areas.
• Only carry out modifications that are described in the instructions for the device. Failure
to observe this requirement cancels the manufacturer's warranty and the product
approvals.
Persons who install, connect, commission, operate, and service the device in a hazardous
area must have the following specific qualifications:
● They are authorized, trained or instructed in operating and maintaining devices and
systems according to the safety regulations for electrical circuits, high pressures,
aggressive, and hazardous media.
● They are authorized, trained, or instructed in carrying out work on electrical circuits for
hazardous systems.
● They are trained or instructed in maintenance and use of appropriate safety equipment
according to the pertinent safety regulations.
Danger of explosion.
• Only use equipment that is approved for use in the intended hazardous area and
labelled accordingly.

WARNING
Incorrect selection of type of protection
CAUTION
Device damage due to electrical discharge
If the device has already been operated in non-intrinsically safe circuits or the electrical
specifications have not been observed, the safety of the device is no longer ensured for u
in hazardous areas. There is a danger of explosion.
• Connect the device with type of protection "Intrinsic safety" solely to an intrinsically safe
circuit.
• Observe the specifications for the electrical data on the certificate and/or in Chapter
"Technical data".
Danger of explosion in areas subject to explosion hazard.
This device is approved for several types of protection.
1. Decide in favor of one type of protection.
2. Connect the device in accordance with the selected type of protection.
3. In order to avoid incorrect use at a later point, make the types of protection that are not
used permanently unrecognizable on the nameplate.
• Avoid contact with the device or electrical connections without being electrostatically
discharged

Product features
SITRANS TH200 and SITRANS TH300 transmitters can be used in all industries. Their
compact size means that they can be installed in connection heads of type B, in accordance
with DIN43729, or larger. Their input stage means that the following sensor and signal
sources can be connected:
● Resistance thermometer
● Thermocouples
● Resistance-type transmitter/potentiometer
● DC voltage sources
The output signal is an output current of 4 to 20 mA that corresponds to the sensor
characteristic curve.
Explosion-proof transmitters can be installed and operated within potentially explosive
atmospheres in compliance with the information given in the relevant certificates and
approvals and in these Operating Instructions.
The transmitters SITRANS T200-TF / T300-TF and SITRANS T200-TR / T300-TR are parts
of the separately certified devices SITRANS TF (7NG313.-*****) and SITRANS TR200 /
TR300 (7NG303.-*****). Further information is given in the specific product manuals or
product certificates.
● Transmitter with two-wire technology
● Installation in connection heads of type B, in accordance with DIN 43729 or larger, or on
a DIN rail
● With communications capability via the HART protocol rev. 5.9 in SITRANS TH300 or via
a proprietary protocol in SITRANS TH200. This enables, for example, the sensor
activation and measuring range to be programmed.
● Galvanic isolation
● Intrinsically-safe and non-sparking version for use in hazardous areas.
● Two additional test pins for connecting a multimeter make it possible to measure the
current signal without interrupting the current loop.
● Indication of operating status: LED green, flashing red, or red
● Special characteristic curve
● Diagnostic functions in SITRANS TH300: Min/max pointer, runtime meter, simulation

5.1 Safety information when connecting
Danger of explosion in hazardous areas as result of incorrect power supply, e.g. using
direct current instead of alternating current.
• Connect the device in accordance with the specified power supply and signal circuits.
The relevant specifications can be found in the certificates, in Chapter "Technical data
(Page 65)" or on the nameplate.
The 4 to 20 mA input and sensor circuits are electrically isolated and have been tested with a
voltage of 1.5 kV DC/1 minute.
The sensor circuit is reliably galvanically isolated from the auxiliary power supply and signal
circuit, up to a peak value of the rated voltage of 60 V. Be sure to observe the construction
directives valid at the construction location for electrical resources in hazardous areas. In
Europe, this is the standard EN 60079-14.
● Only connect the transmitter, in accordance with the certificate of compliance, to devices
certified as intrinsically-safe.
● If the connection head is made of aluminum, the requirements of EN 60079-26, section
4.3.3, must be observed for uses where the device category 1 G is required.
● The transmitter must be mounted in an enclosure in order to provide a degree of
protection of at least IP20 according to EN60529

5.1 Safety information when connecting
● Install the transmitter in an enclosure meeting the degree of protection IP54 per EN
60529, e.g. in a type B connection head per DIN 43729.
● Adhere to the conditions for installers applicable to this type of protection.
● The maximum approved input voltage is U
= 32 V DC.
n
● Take measures to ensure that the supply voltage (including transients) does not rise
above 140 % of the rated voltage.
Install the transmitter in an enclosure suitable for the respective type of dust and
corresponding Zone in accordance with the inspection certificate valid in your country. The
enclosure shall have at least IP5x protection in accordance with IEC 60529.
If the device has been operated outside the ambient conditions specified for potentially
explosive atmospheres, you may no longer operate the device in potentially explosive
atmospheres. Make sure to permanently mask all Ex markings on the nameplate.
