provided by the equipment may be impaired.
The manufacturer is not liable for damage caused by improper or non-designated use.
2.3 Operational safety
‣Operate the device in proper technical condition and fail-safe condition only.
‣The operator is responsible for 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.

LCAUTION
‣Switch off the power supply before installing or connecting the device. Not conforming
with this can lead to the destruction of electronic components.
‣Do not occupy the display connection. An incorrect connection can destroy the electronics.
5.1 Connection conditions
A Phillips head screwdriver is required to wire the head transmitter with screw terminals. Use
a flat blade screwdriver for the DIN rail housing version with screw terminals. The push-in
terminal version can be wired without any tools.
Proceed as follows to wire a mounted head transmitter:
1. Open the cable gland and the housing cover on the terminal head or the field housing.
2. Feed the cables through the opening in the cable gland.
3. Connect the cables as shown in →  16. If the head transmitter is fitted with push-in
terminals, pay particular attention to the information in the "Connecting to push-in
terminals" section". →  18
4. Tighten the cable gland again and close the housing cover.
In order to avoid connection errors always follow the instructions in the post-connection check
section before commissioning!

 10 Terminal assignment of the DIN rail device
A To check the output current, an ammeter (DC measurement) can be connected between the "Test" and
"-" terminals.
A minimum load of 250 Ω is required in the signal circuit in order to operate the HART®
transmitter via the HART® protocol (terminals 1 and 2).
NOTICE
‣ ESD - electrostatic discharge. Protect the terminals from electrostatic discharge. Failure
to observe this may result in the destruction or malfunction of parts of the electronics.
5.3 Connecting the sensor cables
NOTICE
When connecting 2 sensors ensure that there is no galvanic connection between the
sensors (e.g. caused by sensor elements that are not isolated from the thermowell). The
resulting equalizing currents distort the measurements considerably.
‣The sensors must remain galvanically isolated from one another by connecting each sensor
separately to a transmitter. The transmitter provides sufficient galvanic isolation (> 2 kV
AC) between the input and output.
The following connection combinations are possible when both sensor inputs are assigned:

5.4 Connecting the transmitter
Cable specification
• A normal device cable suffices if only the analog signal is used.
• A shielded cable is recommended for HART® communication. Observe grounding
concept of the plant.
• In the case of the DIN rail version, a shielded cable must be used if the sensor cable
length exceeds 30 m (98.4 ft). The use of shielded sensor cables is generally
recommended.
Please also observe the general procedure on →  16.
