1.6 Permissible process pressure
The permissible process pressure is specied on the type label with
"Process pressure", see chapter "Conguration". For safety reasons,
this range may not be exceeded. This applies even if a measuring cell
with a measuring range (order-related) higher than the permissible
pressure range of the process tting is installed.
1.7 NAMUR recommendations
NAMUR is the automation technology user association in the process
industry in Germany. The published NAMUR recommendations are
accepted as the standard in eld instrumentation.
The device fullls the requirements of the following NAMUR recom-
mendations:
• NE 21 – Electromagnetic compatibility of equipment
• NE 53 – Compatibility of eld devices and display/adjustment
components
• NE 107 – Self-monitoring and diagnosis of eld devices
For further information see www.namur.de.
1.8 Environmental instructions
Protection of the environment is one of our most important duties.
That is why we have introduced an environment management system
with the goal of continuously improving company environmental pro-
tection. The environment management system is certied according
to DIN EN ISO 14001.
Please help us fulll this obligation by observing the environmental
instructions in this manual:
• Chapter "Packaging, transport and storage"
• Chapter "Disposal"

3.1 General instructions for use of the instrument
Protect your instrument against moisture ingress through the following
measures:
• Use the recommended cable (see chapter "Connecting to power
supply")
• Tighten the cable gland
• When mounting horizontally, turn the housing so that the cable
gland points downward
• Loop the connection cable downward in front of the cable gland
This applies mainly to outdoor installations, in areas where humidity is
expected (e.g. through cleaning processes) and on cooled or heated
vessels.
3.2 Ventilation and pressure compensation
The lter element is mounted into the electronics housing. It has the
following functions:
• Ventilation of the electronics housing
• Atmospheric pressure compensation (with relative pressure meas-
uring ranges)
→ In case of horizontal mounting, turn the housing so that the lter
element points downward after the instrument is installed.This
provides better protection against buildup.

With the following instruments a blind plug is installed instead of the
lter element:
• Instruments in protection IP 66/IP 68 (1 bar) - ventilation via capil-
laries in non-detachable cable
• Instruments with absolute pressure

4 Connecting to the bus system
4.1 Connecting
The voltage supply and signal output are connected via the spring-
loaded terminals in the housing.
Connection to the display and adjustment module or to the interface
adapter is carried out via contact pins in the housing.
Information:
The terminal block is pluggable and can be removed from the
electronics. To do this, lift the terminal block with a small screwdriver
and pull it out. When reinserting the terminal block, you should hear it
snap in.
Proceed as follows:
1. Unscrew the housing lid
2. If a display and adjustment module is installed, remove it by turn-
ing it slightly to the left.
3. Loosen compression nut of the cable gland and remove blind
plug
4. Remove approx. 10 cm (4 in) of the cable mantle, strip approx.
1 cm (0.4 in) of insulation from the ends of the individual wires
5. Insert the cable into the sensor through the cable entry

Fig. 4: Connection steps 5 and 6 - Double chamber housing
6. Insert the wire ends into the terminals according to the wiring plan
Information:
Solid cores as well as exible cores with wire end sleeves are insert-
ed directly into the terminal openings. In case of exible cores without
end sleeves, press the terminal from above with a small screwdriver,
the terminal opening is then free. When the screwdriver is released,
the terminal closes again.
You can nd further information on the max. wire cross-section under
"Technical data - Electromechanical data"
7. Check the hold of the wires in the terminals by lightly pulling on
them
8. Connect the screen to the internal ground terminal, connect the
external ground terminal to potential equalisation
9. Tighten the compression nut of the cable entry gland. The seal
ring must completely encircle the cable
10. Reinsert the display and adjustment module, if one was installed
11. Screw the housing lid back on
The electrical connection is nished.
