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/..DIV1
and ultrasonic compact flowmeters with type designation OPTISONIC 3400 C(/i)- DIV1 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.
• For Class II, group E and F the maximum allowed surface temperature is limited to 200°C and
for Class II, group G and Class III it is limited to 165°C.
2.2 UFC 400 F(/i)-DIV1
TEMPERATURE LIMITS 2
The UFC 400 F/…-DIV1 flow converter in remote design is suitable for ambient temperatures in
the range -40 to +60°C. The surface temperature always remains below 80°C.
The flow converter inremote 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.
2.3 OPTISONIC 3400 C(/i)-DIV1
The OPTISONIC 3400 C/…-DIV1 compact flowmeter is suitable for ambient temperatures in
the range of -40...60°C.

3.1 General
In the case of separate systems, the electrical connection between OPTISONIC 3000 F/...-DIV1
ultrasonic flow sensor and UFC 400 F...-DIV1 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

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 regulations ANSI/ISA RP 12.06.01 - ANSI/NFPA 70). 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.
CAUTION!

4.1 General
The OPTISONIC 3400 C(/i) -DIV1 compact flowmeter and UFC 400 F(/i) -DIV1 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-
2
sectional area of at least 4 mm
The display cover seals the electronics compartment of the converter housing and provides type
of protection “explosion-proof enclosure”. The terminal compartment is default in type of
protection "non-incendive" and can optionally be performed as explosion-proof enclosure .
The threaded joints formed by the covers and housing are a tight fit due to the requirements for
type of protection “explosion-proof 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.
WARNING!
Allow the electronics to de-energize before opening the electronics compartment of the flow
converter housing. Wait at least 35 minutes for T6 and 10 minutes for T5 before opening.

devices (e.g. intrinsically safe isolation amplifiers), even if such devices are installed in a nonhazardous location !
Connection to non-I.S. devices, cancels the intrinsically safeproperties 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.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 installed in a Division 2, the non-incendive 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.

WARNING!
the following instructions must always be carefully followed, if the housing of the signal
converter has to be opened respectively closed again.
MAINTENANCE AND SERVICE 5
Before opening:
• Make absolutely sure that there is no explosion hazard!
• Make sure that all connecting cables are safely isolated from all external sources!
• Allow the electronics to de-energize before opening the electronics compartment of the
converter housing. Wait at least 35 minutes for T6 and 10 minutes for T5 before opening.
When the instructions above are strictly followed, the display cover (includes glass window) of
the electronics compartment may be removed. First unscrew the head screw with internal
hexagon socket set (size M4) of the interlocking device by a No. 3 Allen key, until the cover can
rotate freely.
After opening:
• Before the cover is screwed back onto the housing, the screw-thread must be clean and wellgreased with an acid and resin-free grease, e.g. PTFE grease.
• Screw the cover as tight as possible onto the housing by hand, until it cannot be opened by
hand anymore. Fixate the screw of the interlocking device tight with the No. 3 Allen key.
