LCAUTION
‣Switch off power supply before installing or connecting the device. Failure to observe this
may result in destruction of parts of the electronics.
‣When installing Ex-approved devices in a hazardous area please take special note of the
instructions and connection schematics in the respective Ex documentation added to these
Operating Instructions. Your supplier is available for assistance if required.
‣Do not occupy the display connection. An incorrect connection can destroy the electronics.
A Phillips head screwdriver is required to wire the head transmitter with screw terminals.
A flat-bladed screwdriver must be used for the version with spring terminals and for the DIN
rail transmitter.
NOTICE
Do not overtighten the screw terminals, as this could damage the transmitter.
‣Maximum torque = 1 Nm (¾ pound-feet).
For wiring a mounted head transmitter, proceed as follows:
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 . If the head transmitter is fitted with spring terminals,
pay particular attention to the information in the "Connecting to spring terminals"
section" .
4. Retighten the cable gland and close the housing cover.
In order to avoid connection errors always take note of the hints given in the section

A To check the output current, an amperemeter (DC measurement) can be connected between the "Test"

To operate the device via the HART® protocol (terminals 1 and 2), a minimum load of 250 Ω is
required in the signal circuit.
NOTICE
‣ ESD - electrostatic discharge. Protect the terminals from electrostatic discharge. Failure
to observe this may result in destruction or malfunction of parts of the electronics.
5.2 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.

LCAUTION
‣Switch off power supply before installing or connecting the transmitter. Failure to observe
this may result in destruction of parts of the electronics.
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.
• On the sensor side, shielded cables must be used for the DIN rail transmitter from a
length of 30 m (98.4 ft).
Please also observe the general procedure on (→  16).

• The terminals for connecting the signal cable (1+ and 2-) are protected against reverse
polarity.
• Conductor cross-section:
– Max. 2.5 mm2 for screw terminals
– max. 1.5 mm2 for spring terminals. Min. stripping length of wire10 mm (0.39 in).
5.4 Shielding and grounding
Optimum electromagnetic compatibility (EMC) can only be guaranteed if the system
components and, in particular, the lines are shielded and the shield forms as complete a cover
as possible.
HART® communication allows three different types of shielding:
• Shielding at both ends
• Shielding at one end on the feed side with capacitance termination at the field device
• Shielding at one end on the feed side
The best results with regard to EMC are achieved in most cases with one-sided shielding on
the feed side (without capacitance termination at the field device). Operation in the event of
disturbance variables as per NAMUR NE21 is thus guaranteed.
