Safety information
The corresponding data sheets and the declaration of
conformity are an integral part of this document.
Intended use
Laws and regulations applicable to the usage or planned
purpose of usage must be observed. Devices are only
approved for proper usage in accordance with intended use.
Improper handling will result in voiding of any warrantee or
manufacturer's responsibility.
The devices are not suitable for the isolation of signals in
power engineering.
Protection of operating personnel and the system is not
ensured if the product is not used in accordance with its
intended use.
Installation and commissioning
Commissioning and installation must be carried out by
specially trained and qualified personnel only.
Installation of the interface devices in the
safe area
The devices are constructed to satisfy the IP20 protection
classification and must be protected from adverse
environmental conditions such as water spray or dirt
exceeding the pollution degree 2.
The devices must be installed outside the hazardous area!
The installation of the intrinsically safe circuits is to be
conducted in accordance with the relevant installation
regulations. It is especially important to ensure that all non-
intrinsically safe circuits are safely isolated (see section
"Internal connections").
The respective peak values of the field device and the
associated device with regard to explosion protection should
be considered when connecting intrinsically safe field devices
with the intrinsically safe circuits of devices (demonstration of
intrinsic safety). EN 60079-14/IEC 60079-14 is to be observed
(where appropriate). The K*D0-LGH* is passive, the
intrinsically safe data corresponds to that in the connected
devices.
When connecting several intrinsically safe current circuits,
these current circuits are to be considered as connected.
Installation and commissioning of the
interface devices within Zone 2/Div. 2 of the
hazardous area
Only devices with the corresponding manufacturer's
declaration of conformity or separate certificate of conformity
can be installed in Zone 2/Div. 2.
The individual data sheets indicate whether these conditions
are met.
The devices should be installed in a switch or junction box that:
• meets at least IP54 in accordance to EN 60529.
• meets to the requirements of resistance to light and
resistance to impact according to EN 60079-0/
IEC 60079-0.
• meets to the requirements of thermal endurance according
to EN 60079-15/IEC 60079-15.
• must not cause ignition danger by electrostatic charge
during intended use, maintenance and cleaning.
The installation of the intrinsically safe circuits is to be
conducted in accordance with the relevant installation
regulations. It is especially important to ensure that all non-
intrinsically safe circuits are safely isolated (see section
"Internal connections").
The respective peak values of the field device and the

intrinsically safe data corresponds to that in the connected
devices.
When connecting several intrinsically safe current circuits,
these current circuits are to be considered as connected.
The manufacturer's declaration of conformity should be
observed. It is especially important to observe the "special
conditions" if these are included in the certificates.
Repair and maintenance
Maintenance is not required.
Fault elimination
Only those changes that are listed in the section "Internal
connections" may be performed on devices that are operated
in connection with hazardous areas. Repairs to a device may
also only be performed at these locations.

jumpers possible, for intrinsically safe
and non-intrinsically safe circuits

jumpers possible, for intrinsically safe
and non-intrinsically safe circuits

safe and non-intrinsically safe circuits

Place Holder Barrier – K-System
Isolation coordinates for installations for
galvanic isolation according to EN 50178
and EN 61140 or EN 60079-11
The devices are built-in devices or electronic equipment for
use in secluded electrical operating sites where only skilled
personnel or electrically instructed personnel will have
admission or access.
The devices are assessed for pollution degree 2 and
overvoltage category II according to EN 50178.
No insulation is present within terminals 1 to 4 and 5 to 8 of the
KCD0-LGH and/or within terminals 1 to 6 and 7 to 15 of the
KFD0-LGH*.
Terminals 1 to 4 of KCD0-LGH are galvanically isolated from
terminals 5 to 10 and/or terminals 1 to 6 of
KFD0-LGH* from terminals 7 to 15 in accordance with
EN 50178/IEC 62103 up to a voltage of 300 Vrms and/or. in
accordance with EN 60079-11/IEC 60079-11 up to a peak
value of the rated voltage of 375 V. This applies only if the
internal connections are designed appropriately (see section
"Internal connections").
