2 TEMPERATURE LIMITS
2.1 General
Due to the influence of the process medium temperature (and heating temperature for HJversions), ultrasonic flow sensors in field design with type designation OPTISONIC 3000 F/..Ex
and ultrasonic compact flowmeters with type designation OPTISONIC 3400 C(/i)- Ex are not
allocated to any fixed temperature class. See the temperature classification tables on the
following page for more details. The temperature limits apply under the following conditions:
• The device is installed and operated in accordance with the installation directions given in the
manual.
• The device is not heated up by any additional heat radiation (direct solar radiation, heat from
adjacent plant parts) so causing it to operate above the permissible ambient temperature
range.
• Insulation is not hindering free ventilation of the ultrasonic signal converter housing.
2.2 UFC 400 F(/i)-Ex
The UFC 400 F/…-Ex flow converter in remote design is suitable for ambient temperatures in
the range -40 to +65°C when equipped with basic I/O and -40 to +60°C for all other I/O
configurations.
The surface temperature always remains below 80°C. The flow converter in
remote design is not influenced by the process temperature, because it is installed on a
distance of the remote flow sensor. It therefore has a temperature rating of T6.
OPTISONIC 3400
2.3 OPTISONIC 3400 C(/i)-Ex
The OPTISONIC 3400 C/…-Ex compact flowmeter is suitable for ambient temperatures in
the range of -40...65°C, when equipped with basic I/O, and suitable for an ambient temperature
range of -40…60°C for all the other I/O configurations.

3 CONNECTION OF SEPARATE SYSTEMS
3.1 General
In the case of separate systems, the electrical connection between OPTISONIC 3000 F/...-Ex
ultrasonic flow sensor and UFC 400 F...-Ex ultrasonic signal converter is established via a signal
cable of type MR06-RG316. This cable consists of six coaxial cables surrounded by an additional
screen and outer insulation layer. The ends of the coaxial cables are provided with SMB plugs.
The signal cable is included with the field system by KROHNE.
3.2 Cable marking
The SMB plugs of the coaxial cables are marked by yellow tubing with a black number of
subsequently 1.1, 1.2, 2.1, 2.2, 3.1 and 3.2. The first number represents the path 1, 2 or 3 and the
second the transducer of that path (1 or 2). The marking of the SMB counter-plugs in the
connection box of the signal converter is respectively 1.1, 1.2, 2.1, 2.2, 3.1 and 3.2. Also refer to

3.4 Equipotential bonding
3.4.1 Signal converter
CONNECTION OF SEPARATE SYSTEMS 3
The UFC 400 F...-Ex ultrasonic signal converter must always
equipotential bonding system of the installation in the hazardous classified location. For this
purpose it must be connected to the external U-clamp screw terminal (size M5) of the UFC 400 F
converter.
The separate bonding conductor must be at least 4 mm
it is mechanically protected, see Clause 413 of HD 384.4.41 or IEC 364-4-41. Make sure that the
core of the bonding wire is properly mounted under the U-clamp of the PE-terminal and that the
screw is tightly fixed.
The intrinsically safe transducer circuits of the UFC 400 F signal converter are galvanically
isolated from earth, therefore an equipotential bonding conductor between the flow sensor
(grounded intrinsically safe transducer circuits) and the signal converter (floating-intrinsically
safe transducer circuits) does not have to be connected, but can be used if desired.

4.1 General
The OPTISONIC 3400 C(/i) -Ex compact flowmeter and UFC 400 F(/i) -Ex signal converter
(separate version) must be incorporated in the equipotential bonding system of the installation.
This can be established internally by connection of the protective earth (PE) conductor of the
mains supply system to the internal PE clamp, or externally, by connecting a separate
equipotential bonding conductor to the external U-clamp terminal (size M5) at respectively the
flange of the mounting support (in case of compact instruments) or at the mounting device (for
signal converters in separate version). A separate bonding conductor must have a cross-
sectional area of at least 4 mm
The display cover seals the electronics compartment of the converter housing and provides type
of protection “flameproof enclosure”. The terminal compartment is default in type of protection “increased safety” ("Ex e") and can optionally be performed as flameproof enclosure ("Ex d").
The threaded joints formed by the covers and housing are a tight fit due to the requirements for
type of protection “flameproof enclosure”. Screw the covers on and off with care and never use
excessive force !
Keep the screw-threads free of dirt and well-greased (e.g. with PTFE grease). The grease will
help to prevent the threads from locking due to corrosion.
To unscrew the covers, first release the interlocking devices (one at each cover). Therefore
unscrew the M4 head screw with internal hexagon socket set using a No. 3 Allen key until the
interlocking device can be turned. After the covers are screwed back onto the housing, make
sure that the interlocking devices are properly refitted.

specific version of the UFC 400 converter ordered. Consult the tables with CG35
numbers for details.
The exact I/O-configuration for circuits A, B, C and D is order-specific and can be determined by
the CG35 number shown on the I/O sticker inside the terminal compartment. Therefore check
the data on the back of the UFC 400 electronics unit. The CG35 number contains 10 characters
of which the last three characters (XYZ) determine the configuration of the I/O circuits:

Suitable for connection to an intrinsically safe
fieldbus in accordance with the FISCO model.
The I/O circuits titled “Ex i I/O” and “Ex i Option” are always provided with type of protection
Intrinsic Safety (Ex ia). The I/O-circuits “Fieldbus I/O Profibus-PA” as well as “Fieldbus I/O
Foundation Fieldbus” can be provided with type of protection Intrinsic Safety.
Up to a maximum of 4 intrinsically safe (Ex ia) in-/outputs are possible. All intrinsically safe
circuits are galvanically isolated with respect to earth and each other. To avoid summation of
voltages and current, the wiring of these “Ex ia”-circuits must be sufficiently separated, e.g. in
accordance with the requirements of standard EN 60079-14, clause 12.2.
The “Ex ia” in-/outputs may only be connected to other “Ex ia” or “Ex ib” approved devices (e.g.
intrinsically safe isolation amplifiers), even if such devices are installed in a non-hazardous
location !
Connection to non-“Ex i” devices, cancels the “Ex ia” properties of the flowmeter.
Terminals L and N (or L+ and L-) for connection of the mains supply are not available with type of
protection “intrinsic safety”. To achieve the necessary separation distances between the non-I.S.
and I.S.according to EN 60079-11 between the non-”Ex i” and “Ex i” circuits, the mains terminals
are provided with a semi-circular protection cover with a “snap-in” lock. This cover MUST be
closed before establishing the power supply to the converter.
INFORMATION!
“
For flow converters with an
Ex e” terminal compartment,installed in a Division 2, the nonincendive terminal compartment can be opened in an energized state for short periods of time,
to access the intrinsically safe terminals for possible checks. However, the semi-circular
insulation cover over the non-intrinsically safe mains supply terminals L and N (or L+ and L-)
MUST be kept closed.
