4.3 Installation conditions
4.3.1 Dimensions
For dimensions, please refer to the Technical Information for Deltapilot M TI00437P,
"Mechanical construction" section.
4.4 General installation instructions
• Devices with a G 1 1/2 thread:
When screwing the device into the tank, the flat seal has to be positioned on the sealing
surface
of the process connection. To avoid additional strain on the process isolating diaphragm, the
thread should never be sealed with hemp or similar materials.
• Devices with NPT threads:
– Wrap Teflon tape around the thread to seal it.
– Tighten the device at the hexagonal bolt only. Do not turn at the housing.
– Do not overtighten the thread when screwing. Max. torque: 20 to 30 Nm (14.75 to 22.13
lbf ft)
4.4.1 Mounting sensor modules with PVDF thread
WARNING
!
Risk of damage to process connection!
Risk of injury!
‣Sensor modules with PVDF process connections with threaded connection must be installed
with the mounting bracket provided!
WARNING
!
Material fatigue from pressure and temperature!
Risk of injury if parts burst! The thread can become loose if exposed to high pressure and
temperatures.
‣The integrity of the thread must be checked regularly and the thread may need to be
re-tightened with the maximum tightening torque of 7 Nm (5.16 lbf ft). Teflon tape is
recommended for sealing the ½" NPT thread.
4.5 Installing
• Due to the orientation of the Deltapilot M, there may be a shift in the zero point, i.e. when the
container is empty or partially full, the measured value does not display zero. You can correct
this zero point shift ä25, Section "Function of the operating elements" or ä37,
Section 8.4 "Position zero adjustment".
• The local display can be rotated in 90° stages.
• Endress+Hauser offers a mounting bracket for installing on pipes or walls.
ä14, Section 4.5.6 "Wall and pipe mounting (optional)".

Deltapilot M 4...20 mA HART Installation
Endress+Hauser 11
4.5.1 General installation instructions
• Do not clean or touch process isolating diaphragms with hard or pointed objects.
• The process isolating diaphragm in the rod and cable version is protected against mechanical
damage by a plastic cap.
• If a heated Deltapilot M is cooled during the cleaning process (e.g. by cold water), a vacuum
develops for a short time, whereby moisture can penetrate the sensor through the pressure
compensation (1). If this is the case, mount the Deltapilot M with the pressure compensation
(1) pointing downwards.
• Keep the pressure compensation and GORE-TEX®filter (1) free from contamination.
• The device must be installed as follows in order to comply with the cleanability requirements
of the ASME-BPE (Part SD Cleanibility).:
4.5.2 FMB50
Level measurement
• Always install the device below the lowest measuring point.
• Do not install the device at the following positions:
– in the filling curtain
– in the tank outflow
– in the suction area of a pump

Installation Deltapilot M 4...20 mA HART
12 Endress+Hauser
– or at a point in the tank that can be affected by pressure pulses from the agitator
• The calibration and functional test can be carried out more easily if you mount the device
downstream of a shutoff device.
• Deltapilot M must be included in the insulation for media that can harden when cold.
Pressure measurement in gases
• Mount Deltapilot M with shutoff device above the tapping point so that any condensate can
flow into the process.
Pressure measurement in steams
• Mount Deltapilot M with siphon above the tapping point.
• Fill the siphon with liquid before commissioning.
The siphon reduces the temperature to almost the ambient temperature.
Pressure measurement in liquids
• Mount Deltapilot M with the shutoff device below or at the same level as the tapping point.
4.5.3 FMB51/FMB52/FMB53
• When mounting rod and cable versions, make sure that the probe head is located at a point
as free as possible from flow. To protect the probe from impact resulting from lateral
movement, mount the probe in a guide tube (preferably made of plastic) or secure it with a
clamping fixture.
• In the case of devices for hazardous areas, comply strictly with the safety instructions when
the housing cover is open.
• The length of the extension cable or the probe rod is based on the planned level zero point.
The height of the protective cap must be taken into consideration when designing the layout
of the measuring point. The level zero point (E) corresponds to the position of the process
isolating diaphragm.
Level zero point = E; top of the probe = L.

For details on mounting, see SD00553P/00/A6.
4.5.8 Supplementary installation instructions
Sealing the probe housing
• Moisture must not penetrate the housing when mounting the device, establishing the
electrical connection and during operation.
• Always firmly tighten the housing cover and the cable entries.
4.6 Mounting of the profile seal for universal process mounting
adapter
For details on mounting, see KA00096F/00/A3.
4.7 Closing the housing cover
NOTICE
Devices with EPDM cover seal - transmitter leakiness!
Mineral-based, animal-based or vegetable-based lubricants cause the EPDM cover seal to swell
and the transmitter to become leaky.
‣The thread is coated at the factory and therefore does not require any lubrication.
NOTICE
The housing cover can no longer be closed.
Damaged thread!
‣When closing the housing cover, please ensure that the thread of the cover and housing are
free from dirt, e.g. sand.If you feel any resistance when closing the cover, check the thread
on both again to ensure that they are free from dirt.

5.1 Connecting the device
WARNING
!
Supply voltage might be connected!
Risk of electric shock and/or explosion!
‣Ensure that no uncontrolles processes are activated in the system.
‣Switch off the supply voltage before connecting the device.
‣When using the measuring device in hazardous areas, installation must comply with the
corresponding national standards and regulations and the Safety Instructions or Installation
or Control Drawings.
‣A suitable circuit breaker must be provided for the device in accordance with
IEC/EN61010.
‣Devices with integrated overvoltage protection must be grounded.
‣Protective circuits against reverse polarity, HF influences and overvoltage peaks are
integrated.
Connect the device in the following order:
1. Check that the supply voltage corresponds to the supply voltage indicated on the nameplate.
2. Switch off the supply voltage before connecting the device.
3. Remove housing cover.
4. Guide the cable through the gland. Preferably use a twisted, shielded two-wire cable.
O Is the device undamaged (visual inspection)?
O Does the device comply with the measuring point specifications?
For example:
•Processtemperature
• Process pressure
• Ambient temperature range
•Measuringrange
O Are the measuring point identification and labeling correct (visual inspection)?
O Is the device adequately protected against precipitation and direct sunlight?
O Are the securing screw and securing clamp tightened securely?

5.2 Connecting the measuring unit
5.2.1 Supply voltage
Taking 4 to 20 mA test signal
A 4 to 20 mA test signal may be measured via the test terminals without interrupting the
measurement. To keep the corresponding measured error below 0.1%, the current measuring
device should exhibit an internal resistance of < 0.7 .
5.2.2 Terminals
• Supply voltage and internal ground terminal: 0.5 to 2.5 mm2(20 to 14 AWG)
• External ground terminal: 0.5 to 4 mm2(20 to 12 AWG)
5.2.3 Cable specification
• Endress+Hauser recommends using twisted, shielded two-wire cables.
