WARNING
Improper laying of shielded cables
Danger of explosion through compensating currents between hazardous area and the non-hazardous area.
●Only ground shielded cables that run into the hazardous area at one end.
●
If grounding is required at both ends, use an equipotential bonding conductor.
WARNING
Connecting device in energized state
Danger of explosion in hazardous areas.
●Connect devices in hazardous areas only in a de-energized state.
Exceptions
:
●Circuits of limited energy may also be connected in the energized state in hazardous areas.
●
Exceptions for type of protection "Non-sparking nA" (Zone 2) are regulated in the relevant certificate
WARNING
Incorrect selection of type of protection
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.
Note
Improvement of interference immunity
●
Lay signal cables separate from cables with voltages > 60 V.
●
Use cables with twisted wires.
●
Keep device and cables in distance to strong electromagnetic fields.
●
Use shielded cables to guarantee the full specification according to HART.
●
Refer to HART communication information in Chapter "Technical data (Page 26)".
Note
Limited range of use
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 m
ask all Ex markings on the
nameplate.
WARNING
Risk of explosion when using unsuitable HART device
Only intrinsically safe HART modems or HART communicators are allowed to be operated in the intrinsically safe area or
on intrinsically safe circuits.

Additional requirements for use in dust explosion protected areas
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 Taplus 20 K for a dust layer
with a maximum thickness of 5 mm.

Safety notes for connecting in hazardous TF
WARNING
Risk of explosion due to electrostatic charge
To prevent an electrostatic charge in a hazardous area, close the key cover during operation and tighten the screws
securely.
Type of protection "Flameproof enclosure" and "Dust protection by enclosure"
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.
For SITRANS TF connection in hazardous areas
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).
4.6
Special safety consideration for connecting SITRANS TH300/TH400
●Use shielded cables to ensure the full specification according to HART, PROFIBUS PA, or FOUNDATION Fieldbus
4.7
Test terminals for output signal
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.
