1 Safety instructions
1.1 Designated use
The Cerabar S is a pressure transmitter for measuring pressure and level.
The manufacturer accepts no liability for damages resulting from incorrect use or use other than
that designated.
1.2 Installation, commissioning and operation
• The device must only be installed, connected, commissioned and maintained by qualified and
authorized specialists (e.g. electrical technicians) in full compliance with the instructions in
this manual, the applicable norms, legal regulations and certificates (depending on the
application).
• The specialist must have read and understood this manual and must follow the instructions it
contains. If you are unclear on anything in these Brief Operating Instructions, you must read
the Operating Instructions (on the CD-ROM). The Operating Instructions provide detailed
information on the device/measuring system.
• The device may only be modified or repaired if such work is expressly permitted in the
Operating Instructions (→ see CD-ROM).
• If faults cannot be rectified, the device must be taken out of service and secured against
unintentional commissioning.
• Do not operate damaged devices. Mark them as defective.
1.3 Operational safety and process safety
• Alternative monitoring measures must be taken to ensure operational safety and process safety
during configuration, testing and maintenance work on the device.
• The device is safely built and tested according to state-of-the-art technology and has left the
factory in perfect condition as regards technical safety. The applicable regulations and
European standards have been taken into account.
• Pay particular attention to the technical data on the nameplate.
• Devices for use in hazardous areas are fitted with an additional nameplate. If the device is to
be installed in an explosion hazardous area, then the specifications in the certificate as well as
all national and local regulations must be observed. The device is accompanied by separate
"Ex documentation", which is an integral part of this Operating Instructions. The installation
regulations, connection values and Safety Instructions listed in this Ex document must be
observed. The documentation number of the related Safety Instructions is also indicated on
the additional nameplate.
• If using devices for applications with safety integrity level, the separate manual on functional
safety must be observed thoroughly (→ see CD-ROM).

2 Installation
2.1 General installation instructions
#Warning!
The process seal is not allowed to press on the process isolating diaphragm as this could affect
the measurement result.
!Note!
• If a heated Cerabar S is cooled during the cleaning (e.g. by cold water), a vacuum develops
for a short time, whereby water can penetrate the sensor through the pressure compensation
(1). If this is the case, mount the sensor with the pressure compensation (1) pointing
downwards.
• Keep the pressure compensation and GORE-TEX®filter (1) free from contaminations.

#Warning!
A warning highlights actions or procedures which, if not performed correctly, will lead to personal injury,
a safety hazard or destruction of the instrument.
"Caution!
Caution highlights actions or procedures which, if not performed correctly, may lead to personal injury or
incorrect functioning of the instrument.
!Note!
A note highlights actions or procedures which, if not performed correctly, may indirectly affect operation
or may lead to an instrument response which is not planned.

• Do not clean or touch process isolating diaphragm of the diaphragm seals with hard or pointed
objects.
• Due to the orientation of the Cerabar S, there may be a shift in the measured value, i.e. when
the container is empty, the measured value does not display zero. You may correct this zero
point shift either directly on the device using the "E"-key or by remote operation. → See
Page 14, Section "Position of operating elements", Page 15, Section 4.2.2 "Function of the
operating elements" and Page 23, Section 5.1 "Position adjustment".
• For PMP75, please refer to Section 2.3 "Installation instructions for devices with diaphragm
seals", Page 6.
• The PMC71 High temperature version and the PMP75 must only be insulated up to a certain
height.
• To ensure optimal readability of the on-site display, it is possible to rotate the housing up to
380°.
• The onsite display can be rotated in 90° stages.
• Endress+Hauser offers a mounting bracket for installing on pipes or walls.
2.2 Installation instructions for devices without diaphragm seals
PMP71, PMC71
Cerabar S without diaphragm seal are mounted as per the norms for a manometer
(DIN EN 837-2). We recommend the use of shut-off devices and siphons. The orientation
depends on the measuring application.
2.2.1 Pressure measurement
Pressure measurement in gases
• Mount Cerabar S with shut-off device above the tapping point so that any condensate can flow
into the process.
Pressure measurement in steams
• Mount Cerabar S with siphon above the tapping point. The siphon reduces the temperature
to almost ambient temperature.
• Fill the siphon with fluid before commissioning.
Pressure measurement in liquids
• Mount Cerabar S with shut-off device below or at the same level as the tapping point.

Installation Cerabar S 4...20 mA HART
6Endress+Hauser
2.2.2 Level measurement
• Mount Cerabar S below the lowest measuring point.
• Do not mount the device at the following positions:
In the fill flow, in the tank outlet or at a point in the container which could be affected by
pressure pulses from an agitator.
• The calibration and functional test can be carried out more easily if you mount the device after
a shut-off device.
2.3 Installation instructions for devices with diaphragm seals
PMP75
!Note!
• The diaphragm seal, together with the pressure transmitter, forms a closed, calibrated system,
which is filled through openings in the diaphragm seal and in the measurement system of the
pressure transmitter. This openings are sealed and must not be opened.
• Do not remove the protection of the process isolating diaphragm until shortly before
installation.
• When using a mounting bracket, sufficient strain relief must be ensured for the capillaries in
order to prevent the capillary bending down (bending radius ≥ 100 mm).
• Please note that the hydrostatic pressure of the liquid column in the capillary can cause zero
point shift. The zero point shift can be corrected. → See Page 14, Section "Position of
operating elements", Page 15, Section 4.2.2 "Function of the operating elements" and
Page 23, Section 5.1 "Position adjustment".
• Please note the application limits of the diaphragm seal filling oil as detailed in the Technical
Information for TI00383P, Section "Planning instructions for diaphragm seal systems" or at
"www.endress.com/applicator".
In order to obtain more precise measurement results and to avoid a defect in the device, mount
the capillaries as follows:
• vibration-free (in order to avoid additional pressure fluctuations)
• not in the vicinity of heating or cooling lines
• insulate if the ambient temperature is below ore above the reference temperature
• with a bending radius of ≥100 mm.

2.3.1 Vacuum application
For applications under vacuum, Endress+Hauser recommends mounting the pressure
transmitter underneath the diaphragm seal. A vacuum load of the diaphragm seal caused by the
presence of filling oil in the capillary is hereby prevented.
When the pressure transmitter is mounted above the diaphragm seal, the maximum height
difference H1 in accordance with the illustration below on the left must not be exceeded. The
maximum height difference is dependent on the density of the filling oil and the smallest ever
pressure that is permitted to occur at the diaphragm seal (empty container), see illustration
below, on the right.
