moderate injury.
NOTICE
The signal word ‘NOTICE’ indicates possible material damage.
Note
‘Note’ indicates useful or important information about the
product.

CoriolisMaster FCB400, FCH400 CORIOLIS MASS FLOWMETER | CI/FCB400/FCH400-EN REV. G 5
Intended use
This device is intended for the following uses:
• To convey liquids and gases (including unstable measuring
media).
• To meter mass flow directly.
• To meter volumetric flow (indirectly via mass flow and
density).
• To measure the density of the measuring medium.
• To measure the temperature of the measuring medium.
The device has been designed for use exclusively within the
technical limit values indicated on the identification plate and in
the data sheets.
When using measuring media, the following points must be
observed:
• Measuring media may only be used if, based on the state
of the art or the operating experience of the user, it can
be assured that the chemical and physical properties
necessary for operational security of the materials of the
wetted parts of the flowmeter sensor will not be
adversely affected during the operating time.
• Media containing chloride in particular can cause
corrosion damage to stainless steels which, although not
visible externally, can damage wetted parts beyond repair
and lead to the measuring medium escaping. It is the
operator's responsibility to check the suitability of these
materials for the respective application.
• Measuring media with unknown properties or abrasive
measuring media may only be used if the operator is able
to perform regular and suitable tests to ensure the safe
condition of the device
Improper use
The following are considered to be instances of especially
improper use of the device:
• Operation as a flexible compensating adapter in piping,
for example for compensating pipe offsets, pipe
vibrations, pipe expansions, etc.
• For use as a climbing aid, for example for mounting
purposes.
• For use as a bracket for external loads, for example as a
support for piping, etc.
• Material application, for example by painting over the
housing, name plate or welding/soldering on parts.
• Material removal, for example by spot drilling the
housing.
Notes on data safety
This product is designed to be connected to and to
communicate information and data via a network interface.
It is operator’s sole responsibility to provide and continuously
ensure a secure connection between the product and your
network or any other network (as the case may be).
Operator shall establish and maintain any appropriate measures
(such as but not limited to the installation of firewalls,
application of authentication measures, encryption of data,
installation of anti-virus programs, etc.) to protect the product,
the network, its system and the interface against any kind of
security breaches, unauthorized access, interference, intrusion,
leakage and / or theft of data or information.
ABB Automation Products GmbH and its affiliates are not liable
for damages and / or losses related to such security breaches,
any unauthorized access, interference, intrusion, leakage and /
or theft of data or information.
Warranty provisions
Using the device in a manner that does not fall within the scope
of its intended use, disregarding this manual, using
underqualified personnel, or making unauthorized alterations
releases the manufacturer from liability for any resulting
damage. This renders the manufacturer's warranty null and void.

All outputs are electrically isolated from each other and from the power supply.
Digital outputs 41 / 42 and 51 / 52 are not electrically isolated from each other. Terminals 42 / 52 have the same potential.
* Only in conjunction with additional ‘24 V DC loop power supply (blue)’ plug-in card in slot OC1.
** Only in conjunction with current output UCO / 32 in ‘power mode’, see Current output Uco / 32 as loop power supply for digital output 41 / 42 or 51 / 52 on
page 47.

Special connection conditions
Note
The AS plug-in card (24 V DC loop power supply) may only be
used to power the internal inputs and outputs on the device.
It must not be used to power external circuits!
Note
If the protective earth (PE) is connected in the flowmeter's
terminal box, you must ensure that no dangerous potential
difference can arise between the protective earth (PE) and the
potential equalization (PA) in areas with explosion risk.
Note
• For devices with a power supply of 11 to 30 V DC, on-site
external overvoltage protection must be provided.
• You must make sure that the overvoltage is limited to
140 % (= 42 V DC) of the maximum operating voltage.
The output circuits are designed so that they can be connected
to both intrinsically-safe and non-intrinsically-safe circuits.
• Combining intrinsically safe and non-intrinsically safe circuits
is not permitted.
• On intrinsically safe circuits, potential equalization should be
established along the entire length of the cable used for the
signal outputs.
• The rated voltage of the non-intrinsically safe circuits is
UM= 30 V.
• Intrinsic safety is preserved If the rated voltage UM= 30 V is
not up-scaled when connections are established to non-
intrinsically safe external circuits.
• The information in Changing the type of protection on
page 24 must be observed when changing the type of
protection.
Devices connected to the relevant equipment must not be
operated at over 250 Vrms AC or 250 V DC to ground.
Installation in accordance with ATEX or IECEx must comply with
the applicable national and international standards and
directives.
Installation in the USA or Canada must comply with ANSI / ISA
RP 12.6, ‘Installation of intrinsically safe systems for hazardous
(classified) locations’, the ‘National Electrical Code (ANSI / NFPA
70), sections 504, 505’ and the ‘Canadian electrical code (C22.1-
02)’.
Apparatus connected to the flowmeter must have appropriate
explosion protection approval in accordance with the Entity
concept.
The apparatus must have intrinsically safe circuits.
The apparatus must be installed and connected in accordance
with the relevant manufacturer documentation.
The electrical specifications in Electrical data on page 17 must
be observed.
Ethernet communication
DANGER
Explosion hazard due to improper installation!
Ethernet Option Cards are designed only for use in hazardous
applications Zone 2 / Division 2.
The output circuits are designed so that different topologies
such as daisy chain or point to point can be connected. See
Installation diagram for detailed information.
• It is not permitted to combine both topologies.
• Ethernet communication is only available for installations in
Zone 2/Division 2.
• The rated voltage of these non-intrinsically safe circuits are
UM = 57 V.
