level detection of liquids.
1.2 Installation, commissioning and operation
The Liquicap M has been safely built with state-of-the-art technology and meets all
applicable standards and EU directives. However, if it is used improperly or if it is not put to
its intended use, it can be a source of application-related dangers, such as product overflow
due to incorrect installation or configuration. Therefore, the installation, electrical
connection,commissioning, operation and maintenance of the measuring device only may
be carried out by trained specialist personnel authorized by the facility's owner/operator for
this purpose. The specialist personnel must have read and understood these Operating
Instructions and must follow the instructions they contain. Modifications or repairs to the
device can be carried out only if it is expressly stated in the Operating Instructions that these
are permitted.
1.3 Operational safety
When performing configuration, testing and maintenance work on the device, alternative
supervisory measures must be taken to guarantee the operational safety and process safety.
1.3.1 Hazardous areas
If the measuring system is used in hazardous areas, the corresponding national/federal
standards and regulations must be observed. The device is accompanied by separate Ex
documentation, which is an integral part of this documentation. Observe the installation
instructions, connection data and safety instructions provided there.
• Ensure that the specialists are adequately trained.
• Observe the metrological and technical safety requirements for the measuring points.
1.4 Product safety
This measuring device is designed in accordance with good engineering practice to meet
state-of-the-art safety requirements, has been tested, and left the factory in a condition in
which it is safe to operate. It meets general safety standards and legal requirements.
1.4.1 CE mark
The measuring system meets the legal requirements of the applicable EC guidelines. These
are listed in the corresponding EC Declaration of Conformity together with the standards
applied.
Endress+Hauser confirms successful testing of the device by affixing to it the CE mark.
1.4.2 EAC conformity
The measuring system meets the legal requirements of the applicable EAC guidelines.
These are listed in the corresponding EAC Declaration of Conformity together with the

3.3 Installation instructions
3.3.1 Installation
Liquicap M FTI51 (rod probe) can be installed from above, from below and from the side.
Liquicap M FTI52 (rope probe) can be installed vertically from above.
!Note!
• The probe may not come into contact with the container wall!
• Recommended distance from the container floor: 10 mm.
• If multiple probes are mounted next to each other, a minimum distance of 500 mm
(19.7 in) between the probes must be observed.
• Do not install probes in the area of the filling curtain!
• Make sure the probe is at a sufficient distance from the agitator.
• If there are strong lateral loads, use rod probes with a ground tube.

3.3.2 Support for marine approval (GL)
Fully insulated rod probes can be supported conductively or non-conductively.
Partially insulated rod probes may only be supported with insulation at the uninsulated
probe end.
!Note!
Rod probes with a diameter of 10 mm and 16 mm have to be supported with a length 1 m
(see drawing).
L00-FMI5xxxx-06-05-xx-xx-077
Example for calculating distances:
Probe length L = 2000 mm.
L/4 = 500 mm
L/2 = 1000 mm

3.4 Measuring conditions
3.5 Installation examples
3.5.1 Rod probes
Conductive tanks (metal tanks)
If the process connection of the probe is insulated from the metal tank (e.g. using seal
material), the ground connection on the probe housing must be connected to the tank using
a short line.
!Note!
• A fully insulated rod probe may be neither shortened nor extended.
• If the insulation of the probe rod is damaged, this will falsify the measurement result.
• These application examples show vertical installation for MAX point level detection.
Notes!
• When installing in a nozzle, use inactive
length (L3).
• Probes with active buildup
compensation must be used for high-
viscosity liquids that tend to form
buildup.
• Fully insulated rod and rope probes have
to be used for pump control (S
operation).
The switch-on and switch-off points are
determined by the empty and full
calibration.
– The maximum length depends on the
probe used.
A 16 mm rod generates a capacitance
of 380 pF/m in a conductive
liquid.
With a maximum span of 1600 pF,
this gives 1600pF/380pF per m =
4 m total length.
• In the case of nonconductive media:
use a ground tube

3.5.3 Shortening the rope
!Note!
Refer to the operating manual for the rope shortening kit KA061F/00
3.5.4 Tensioning weight with bracing
The end of the probe needs to be secured if the probe would otherwise touch the silo wall or
another part in the tank. An anchor hole is provided in the probe weight for this purpose.
The bracing can be attached to the tank wall so that it is either conductive or insulating.
To prevent the danger of a high tensile load, the rope should be loose or braced with a spring.
The maximum tensile load must not exceed 200 N.

3.7.1 Shortening the connecting cable
"Caution!
A recalibration must be performed before commissioning Page 42ff.
!Note!
The maximum connection length between the probe and the separate housing is 6 m. When
ordering a device with a separate housing, the desired length must be specified.
If the connecting cable is to be shortened or passed through a wall, it must be separated from
the process connection. To do so, proceed as follows:
• Unscrew the pressing screw (1) using an open-end wrench AF22. If necessary, hold the
process
connection. In doing so, ensure that neither the connecting cable nor the probe is turned
in the process.
• Pull the insert seal (2) out of the cable gland (3).
• Using an open-end wrench (AF22), disconnect the cable gland (3) from the adapter disk.
If necessary, hold it against the adapter disk (6) using an open-end wrench AF34.
• Disconnect the adapter disk (6) from the adapter bushing (18).
• Remove the snap ring with a snap ring pliers.
• Grip the nut (M6) on the blade plug with a pliers and pull out the blade plug.
• Then, shorten the connecting cable to the desired length.
• If the separate housing has to be mounted in a different room than the probe, you can now
route the connecting cable through the wall.
• You can now reassemble the device by following the reverse order of steps.
!Note!
• If you shorten the connecting cable, we recommend reusing all strands with
ring terminals.
• If the strands are not to be reused, the crimp connections of the new ring terminals
attached must be insulated with a heat-shrinking sleeve tube, for example (danger of
short circuit).
