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.
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.

Temperature Trip Amplifier KFD2-GU-(Ex)1
Overview
The temperature trip amplifier KFD2-GU-(Ex)1 of the
K-system are used for temperature measurement.
Further information (e. g. certificates, the data sheets
for the device and the manual for the K-system) can
be found on our Internet page www.pepperlfuchs.com/pa (under product search, enter *GU*).
• You can connect resistance temperature sensors or thermocouples to
the input of the device (types: B, E, J, K, L, N, R, S, T). The device can also process a unit current
signal or a unit voltage signal.
• Two different limit values of the input signal can be monitored with the aid of the two relay outputs
on the device and parameters can be set freely for them.
• You can connect a PC for programming and diagnostics with PACTware™ (see section 6 and
section 7) on the device.
2.2 Versions
The following versions of the device are available:
• KFD2-GU-1, device with a power supply 24 V DC for connection of field devices in the safe area
• KFD2-GU-Ex1, device with a power supply 24 V DC for connection of field devices in areas exposed
to danger of explosion

3 Safety Instructions
The device may only be operated by trained personnel in a manner corresponding to
this manual.
Protection of opera ti ng pe rsonn el and the plant is only guar antee d if the devi ce is used
according to their specifications. Any use other than that described in the manual
endangers the safety and functionality of the device and the connected systems.
The device may only be mounted, connected and adjusted by electrical professionals
outside the explosion hazardous area.
If malfunctions cannot be eliminated, pl aces the device out of service and protect them
from accidental use. The device may only be repaired directly by the manufacturer
Pepperl+Fuchs. Any opening or change in the device is 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
ATEX directive 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
284503 2015-09
The temperature t rip am plifier KFD2-GU-(E x)1 are co nstructed i n prote ction class IP20
and must therefore be protected from undesirable environmental conditions (water,
dust, small foreign objects).
The devices of the K-System from Pepperl+Fuchs can be mounted on a
35 mm top-hat 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 *GU*).

5.2 Connection
The KF 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.
