2Overview
2.1 Application
The devices of the K-System from Pepperl+Fuchs are used to transmit signals between field
devices and the process control system or control.
Devices with the "Ex" code in their type identifiers are suitable for connection to field devices in
the hazardous area. The field current circuits of these devices are intrinsically safe and are
galvanically isolated from the not intrinsically safe circuits. The devices thus represent an
electrical isolation between the hazardous area and the safe area within a system.
Devices without an "Ex" code can be used for signal transmission between field devices in the
safe area and the process control system or the control.
This symbol indicates a warning about a possible danger.
Failure to observe this warning may result in personal injury or death, or property
damage or destruction.
This symbol warns of a possible fault.
If the instruction given in this warning is not heeded, the device and any systems or
plants connected to it could develop a fault or even fail completely.
This symbol brings important information to your attention.

EN - 3
EN
The temperature converters KCD2-
UT2-(Ex)1 of the K-System (referred to
as UT2) are used for temperature
measurement.
Resistance temperature detectors,
thermocouples, potentiometers or
voltage sources can be connected to
the inputs of the converter.
The device converts the input signals
into proportional current signals or
voltage signals.
The output signals can, forexample, be
forwarded to displays or analog inputs
of the process control system.
Further information (e. g. certificates, the data sheets for the UT2 devices and the operating
instructions for the K-System) can be found on our Internet page www.pepperl-fuchs.com/pa
(under product search, enter *UT2*).
2.2 Versions
The following versions of the temperature transmitter are available:
1 = 1 input, 1 output
Ex = for connection of field devices in areas exposed to
danger of explosion
without identifier letters = for connection of field devices in
the safe area

Safety instructions
EN
3 Safety instructions
The devices may only be operated by trained personnel in a manner corresponding
to this operating manual.
Protection of operating personnel and the plant is only guaranteed if the devices
are used according to their specifications. Any use other than that described in the
manual endangers the safety and functionality of the devices and the connected
systems.
The devices may only be mounted, connected and adjusted by electrical
professionals outside the explosion hazardous area.
If malfunctions cannot be eliminated, place the devices out of service and protect
them from accidental use. The devices may only be repaired directly by the
manufacturer Pepperl+Fuchs. Any opening or change in the units are dangerous
and are therefore not to be performed. They void any warranty.
Responsibility for adhering to local safety regulations and directives is held by the
operator.

4 Explosion protection
For primary explosion protection, that is, measures to avoid or
restrict the production of a dangerous, explosive atmosphere,
please consult the directive 1999/92/EC (ATEX 137) or the
corresponding national provisions.
For secondary explosion protection, that is, measures to avoid the
ignition of a surrounding explosive atmosphere by electrical
equipment, Pepperl+Fuchs will gladly provide you with a copy of the
"Ex-protection manual" for a nominal fee.
Please pay particular attention to EN 60079-0, EN 60079-11 and
EN 60079-15 or the corresponding national provisions.
Pepperl+Fuchs also provides a seminar on the topic of explosion
protection.
5 Mounting and connection
5.1 Mounting
The devices of the K-Systems from Pepperl+Fuchs and thus also the
temperature transmitters KCD2-UT2-(Ex)1 can be mounted on a 35 mm
DIN mounting rail corresponding to EN 60715. The devices must be
snapped onto the rail vertically, and never slanted or tipped to the side.
Further mounting alternatives, e. g. using the Power Rail, can be found in
the operating instructions for the K-System on our Internet page
www.pepperl-fuchs.com/pa (under product search, enter *UT2*).
The devices are constructed in protection class IP20 and must therefore be
protected from undesirable environmental conditions (water, dust, small foreign
objects).

5.2 Connection
The KC series' slip-off terminals significantly simplify connection and construction of switching
cabinets. They allow quick and error-free exchange of the unit when service is needed.
The terminals can be screwed on, are self-opening, and have generous connection room for a
wire diameter of up to 2.5 mm² and coded plugs, so that leads cannot be confused.
The Intrinsically safe field circuit is connected to the blue terminals 1 to 4 of the KCD2-UT2-Ex-1.
These may be conducted using DIN EN 60079-14 compliant leads into the hazardous area.
The non-intrinsically safe field circuit is connected to the green terminals 1 to 4 of the
KCD2-UT2-1.
The non-intrinsically safe circuit is connected to the green terminals 5 to 10 of the
KCD2-UT2-(Ex)1.
