4.1 General instructions
Devices with threaded tting are screwed into the process tting with
a suitable wrench via the hexagon.
See chapter "Dimensions" for wrench size.
Warning:
The housing or the electrical connection may not be used for screw-
ing in! Depending on the device version, tightening can cause dam-
age, e. g. to the rotation mechanism of the housing.
Protect your instrument against moisture ingress through the following
measures:
• Use a suitable connection cable (see chapter "Connecting to
power supply")
• Tighten the cable gland or plug connector
• Lead the connection cable downward in front of the cable entry or
plug connector
This applies mainly to outdoor installations, in areas where high
humidity is expected (e.g. through cleaning processes) and on cooled
or heated vessels.
Note:
Make sure that during installation or maintenance no moisture or dirt
can get inside the instrument.
To maintain the housing protection, make sure that the housing lid is
closed during operation and locked, if necessary.
Metric threads
In the case of instrument housings with metric thread, the cable
glands are screwed in at the factory. They are sealed with plastic
plugs as transport protection.
You have to remove these plugs before electrical connection.
NPT thread
In the case of instrument housings with self-sealing NPT threads, it is
not possible to have the cable entries screwed in at the factory. The
free openings for the cable glands are therefore covered with red dust
protection caps as transport protection. The dust protection caps do
not provide sucient protection against moisture.
Prior to setup you have to replace these protective caps with ap-
proved cable glands or close the openings with suitable blind plugs.
Note:
For safety reasons, the instrument must only be operated within the
permissible process conditions. You can nd detailed information on
the process conditions in chapter "Technical data" of the operating
instructions or on the type label.

Hence make sure before mounting that all parts of the instrument ex-
posed to the process are suitable for the existing process conditions.
These are mainly:
• Active measuring component
• Process tting
• Process seal
Process conditions in particular are:
• Process pressure
• Process temperature
• Chemical properties of the medium
• Abrasion and mechanical inuences
4.2 Mounting instructions
In vessels with conical bottom it can be advantageous to mount the
device in the center of the vessel, as measurement is then possible
nearly down to the lowest point of the bottom. Keep in mind that
measurement all the way down to the tip of the probe may not be pos-
sible. The exact value of the min. distance (lower blocking distance) is
stated in chapter "Technical data".
Fig. 3: Vessel with conical bottom
Before beginning the welding work, remove the electronics module
from the sensor. By doing this, you avoid damage to the electronics
through inductive coupling.
Do not mount the instruments in or above the lling stream. Make sure
that you detect the medium surface, not the inowing product.

Fig.4:Mountingofthesensorwithinowingmedium
The reference plane for the measuring range of the sensors is the
sealing surface of the thread or ange.
Keep in mind that a min. distance must be maintained below the refer-
ence plane and possibly also at the end of the probe - measurement
in these areas is not possible (blocking distance). These blocking
distances are listed in chapter "Technical data". Keep in mind for the
adjustment that the default setting for the measuring range refers to
water.
The process tting must be sealed if there is gauge or low pressure
in the vessel. Before use, check if the sealing material is resistant
against the measured product and the process temperature.
The max. permissible pressure is specied in chapter "Technical
data" or on the type label of the sensor.
If there is a risk of the coaxial probe touching the vessel wall during
operation due to product movements or agitators, etc., the measuring
probe should be securely xed.
Avoid undened vessel connections, i.e. the connection must be
either grounded reliably or isolated reliably. Any undened change of
this condition can lead to measurement errors.
In case of strong external vibrations or if there is a danger of the co-
axial probe touching the vessel wall, then the probe must be fastened
at the bottom end.
Keep in mind that measurement is not possible below the fastening
point.

5.1 Preparing the connection
Always keep in mind the following safety instructions:
• Carry out electrical connection by trained, qualied personnel
authorised by the plant operator
• If overvoltage surges are expected, overvoltage arresters should
be installed
Warning:
Only connect or disconnect in de-energized state.
The voltage supply is provided by a Probus DP /PA segment coupler.
The voltage supply range can dier depending on the instrument
version. You can nd the data for voltage supply in chapter "Technical
data".
Connection is made with shielded cable according to the Probus
specication. Power supply and digital bus signal are carried over the
same two-wire connection cable.
Use cable with round cross section for instruments with housing and
cable gland. To ensure the seal eect of the cable gland (IP protection
rating), nd out which cable outer diameter the cable gland is suitable
for.
Use a cable gland tting the cable diameter.
Make sure that the entire installation is carried out according to the
Probus specication. In particular, make sure that the bus is termi-
nated with suitable terminating resistors.
You can nd detailed information of the cable specication, installa-
tion and topology in the "ProbusPA-UserandInstallationGuide-
line" on www.probus.com.
Metric threads:
In the case of instrument housings with metric thread, the cable
glands are screwed in at the factory. They are sealed with plastic
plugs as transport protection.
Note:
You have to remove these plugs before electrical connection.
NPT thread:
In the case of instrument housings with self-sealing NPT threads, it is
not possible to have the cable entries screwed in at the factory. The
free openings for the cable glands are therefore covered with red dust
protection caps as transport protection.
Note:
Prior to setup you have to replace these protective caps with ap-
proved cable glands or close the openings with suitable blind plugs.

On plastic housings, the NPT cable gland or the Conduit steel tube
must be screwed into the threaded insert without grease.
Max. torque for all housings, see chapter "Technical data".
Make sure that the cable screen and grounding are carried out ac-
cording to Fieldbus specication. We recommend to connect the
cable screening to ground potential on both ends.
In systems with potential equalisation, connect the cable screening
directly to ground potential at the power supply unit, in the connection
box and at the sensor. The screen in the sensor must be connected
directly to the internal ground terminal. The ground terminal outside
on the housing must be connected to the potential equalisation (low
impedance).
5.2 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
