3.3.1 Installation instructions for devices without a diaphragm seal –
PMC41, PMC45, PMP41, PMP45
!Note!
• If a heated Cerabar M is cooled during a cleaning process (e.g. by cold water), a vacuum develops
for a short time, whereby moisture can penetrate the sensor through the pressure compensation
➀. If this is the case, mount the Cerabar M with the pressure compensation ➀pointing
downwards.
• Keep the pressure compensation and GORE-TEX®filter ➀free from dirt.
• Cerabar M devices without diaphragm seals are mounted as per the norms for a manometer
(DIN EN 839-2). We recommend the use of shutoff devices and siphons. The orientation depends
on the measuring application.
• Do not clean or press the diaphragm with hard or pointed objects.

3.3.2 Installation instructions for devices with diaphragm seals –
PMP46, PMP48
!Note!
• The Cerabar M with a diaphragm seal is screwed in, flanged or clamped, depending on the type
of diaphragm seal.
• Together, a diaphragm seal and the pressure transmitter form a closed, calibrated system which
is filled with oil. The filling hole is sealed and should not be opened.
• Do not clean or press the diaphragm of the diaphragm seals with hard or pointed objects.
• Do not remove diaphragm protection until shortly before installation.
• When using a mounting bracket, sufficient strain relief must be ensured for the capillaries in order
to prevent the capillary from buckling (bending radius ≥ 100 mm).
• Please note that the hydrostatic pressure of the liquid columns in the capillaries can cause zero
point shift. You can correct this zero point shift → see Page 29, Section 6.2.5 "Position adjustment
- only display (bias pressure)" (onsite operation) or via communication → see Page 33,
Section 6.3.7 "Position adjustment - only display (bias pressure)".
• Please note the application limits of the diaphragm seal filling oil as detailed in the Technical
Information for Cerabar M TI399P, "Planning instructions for diaphragm seal systems" section.
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 pipes
• Insulate if the ambient temperature is below or above the reference temperature
• With a bending radius of ≥100 mm.

Installation Cerabar M HART
14 Endress+Hauser
Vacuum application
For applications under vacuum, Endress+Hauser recommends mounting the pressure transmitter
below the diaphragm seal. This prevents a vacuum load of the diaphragm seal caused by the
presence of filling oil in the capillaries.
When the pressure transmitter is mounted above the diaphragm seal, the maximum height
difference H1 - as illustrated in the diagram below left - must not be exceeded. The maximum
height difference depends on the density of the filling oil and the lowest pressure that is permitted
to occur at the diaphragm seal (empty tank), see the following illustration.
Mounting with temperature isolator
P01-PMP4xxxx-11-xx-xx-xx-006
Endress+Hauser recommends the use of temperature isolators in the event of constant extreme fluid
temperatures which lead to the maximum permissible electronics temperature of +85°C (+185°F)
being exceeded. To minimize the influence of rising heat, Endress+Hauser recommends the device
be mounted horizontally or with the housing pointing downwards.
The additional installation height also brings about a zero point shift of approx. 21 mbar due to the
hydrostatic column in the temperature isolator. You can correct this zero point shift → see Page 29,
Section 6.2.5 "Position adjustment - only display (bias pressure)" (onsite operation) or via
communication → see Page 33, Section 6.3.7 "Position adjustment - only display (bias pressure)".

• Connect the device in accordance with the following diagram.
• Where applicable, refit the retaining ring with the onsite display. The grip of the retaining ring
clips in with an audible click.
• Screw down housing cover.
• Switch on supply voltage.

➀Disassembling the onsite display: To release the retaining ring from the electronic insert, push up the latch with
the arrow.
➁The terminal non the electronic insert is for grounding and is already wired internally. If the connecting cable
also has a shielding or ground cable within it, then this may only be connected to the internal ground terminal p
of the housing, not to terminal n. The terminals are designed to take one wire each.
➂4 to 20 mA test signal: you can take a 4 to 20 mA test signal via the terminal lugs without interrupting the
measurement.

4.2 Connecting the DXR375 handheld terminal
• For a Cerabar M with an FM or CSA certificate, perform the electrical connection in accordance
with the "control drawing" (provided in the packaging for Cerabar M).
• To transfer the communication signal without errors, there must be a communication resistor of
at least 250 Ωbetween the connection points and the power supply.
P01-PMx4xxxx-04-xx-xx-xx-014
Fig. 22: ➀Any connection devices.
The handheld terminal can be connected anywhere along the 4 to 20 mA cable. Use an intrinsically safe voltage
source in Ex ia areas (e.g. RN221N).
