Introduction
This manual contains notices you have to observe in order to ensure your personal safety, as well as to prevent damage to property. The
notices referring to your personal safety are highlighted in the manual by a safety alert symbol, notices referring only to property damage
have no safety alert symbol. These notices shown below are graded according to the degree of danger.
If more than one degree of danger is present, the warning notice representing the highest degree of danger will be used. A notice warning of
injury to persons with a safety alert symbol may also include a warning relating to property damage.
The product/system described in this documentation may be operated only by
the relevant documentation, in particular its warning notices and safety instructions. Qualified personnel are those who, based on their
training and experience, are capable of identifying risks and avoiding potential hazards when working with these products/systems.
Note the following:
Siemens products may only be used for the applications described in the catalog and in the relevant technical documentation. If products
and components from other manufacturers are used, these must be recommended or approved by Siemens. Proper transport, storage,
installation, assembly, commissioning, operation and maintenance are required to ensure that the products operate safely and without any
These instructions are a brief summary of important features, functions and safety information, and contain all information

WARNING
Using a damaged or incomplete device
● Do not use damaged or incomplete devices.
CAUTION
Insufficient protection during storage
● Provide additional packaging as necessary.
Danger of explosion in hazardous areas.
To guarantee sufficient protection during transport and storage, observe the following:
● Keep the original packaging for subsequent transportation.
● Devices/replacement parts should be returned in their original packaging.
● If the original packaging is no longer available, ensure that all shipments are properly packaged to provide sufficient
protection during transport. Siemens cannot assume liability for any costs associated with transportation damages.
The packaging only provides limited protection against moisture and infiltration.
Special conditions for storage and transportation of the device are listed in "Technical data" (Page 26).

head per DIN 43729.
● Adhere to the conditions for installers applicable to this type of protection.
● The maximum approved input voltage is Un = 32 V DC.
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 surface temperature of the enclosure is euqal to T
with a maximum thickness of 5 mm.
To prevent an electrostatic charge in a hazardous area, close the key cover during operation and tighten the screws
securely.
Only open devices with type of protection "Flameproof enclosure" in hazardous areas when the power to the device is
turned off, otherwise there is a risk of explosion.
The SITRANS TF comes with a built-in transmitter: SITRANS TH200, TH300, or TH400. See Safety notes for connecting in
hazardous TH200/300 (Page 14).
● Use shielded cables to ensure the full specification according to HART, PROFIBUS PA, or FOUNDATION Fieldbus
plus 20 K for a dust layer
a
The "Test +" and "Test -" test terminals are used for checking the 4 to 20 mA current with an amperemeter. The voltage drop
across the amperemeter must not exceed 0.4 V for a 23 mA output current.

Maintenance
WARNING
Impermissible repair and maintenance of the device
● Repair and maintenance must be carried out by Siemens authorized personnel only.
WARNING
Impermissible repair of explosion protected devices
● Repair must be carried out by Siemens authorized personnel only.
Cleaning the enclosure
WARNING
Electrostatic charge
● Prevent electrostatic charging in hazardous areas.
The device is maintenance-free. However, a periodic inspection according to pertinent directives and regulations must be
carried out.
An inspection can include check of:
● Ambient conditions
● Seal integrity of the process connections, cable entries, and cover screws
● Reliability of power supply, lightning protection, and grounds
Danger of explosion in areas subject to explosion hazard.
● Clean the outside of the enclosure and the display window using a cloth moistened with water or a mild detergent.
● Do not use aggressive cleaning agents or solvents. Plastic components or painted surfaces could be damaged.
Danger of explosion in hazardous areas if electrostatic charges develop, for example, when cleaning plastic enclosures
with a dry cloth.
