Galvanically isolated connection of measuring
two wire transducers by meaning of standard
analog signals 0/4…20 mA from hazardous
area into safe area.
Special conditions for application in zone 2
For installation in zone 2 the device must be
installed in a housing which complies with the
requirements of EN 60079-15 with a minimum
protection degree of IP54 according to
IEC/EN 60529.
With mounting in zone 2 the connecting and
disconnecting of energized non energy limited
circuits is only permitted in non-explosive
atmosphere.
The application of litz-wires recommends the
fixation of cable ends with wire sleeves.
Mounting and Installation (Fig. 4 + 5)
The device is suited for snap-on clamps for
DIN rail mounting (EN 60715).
Devices of the same type may be mounted
directly next to each other. It must be ensured
that heat is conducted away from the device.
Mounting and installation must be carried out in
accordance with the applicable regulations.
The operator is responsible for compliance with
the regulations.
The device must be protected against dust,
dirt, moisture and other environmental influ-
ences as well as against strong electromagnetic
emissions.
It should also be protected against the risks of
mechanical damaging, unauthorized access
and incidental contact.
All installations must be carried out observing
the regulations of EMC protection.

Important information on use of devices
with intrinsically safe circuits
This device is equipped with circuits featuring protection
type „intrinsic safety“ for explosion protection per
EN 60079-11 at terminals which are marked in blue.
The intrinsically safe circuits are approved by the au-
thorised bodies for use in those countries to which the
approval applies.
For correct usage in explosion hazardous areas
please observe and follow the national regulations and
directives strictly.
Non-intrinsically save circuits have to be installed accor-
ding to the national regulations.
Following please find some guidelines referring to the
frame-work directive of the European Union 94/9/EC
(ATEX).
This device is classified as an associated apparatus which
is equipped with intrinsically safe and non-intrinsically
safe circuits. Therefore it may only be installed in the non-
explosion hazardous area in dry clean and well monitored
locations.
If a declaration of conformity or declaration of the manu-
facturer as a category 3 device exists, the device may be
installed in zone 2 and zone 22. Special instructions for
safe operation must be observed. .
It is permitted to connect intrinsically safe equipment
to the intrinsically safe connections of this device.
All electrical equipment must comply with the regulations
applying to use in the respective zone of the explosion
hazardous area.
If the intrinsically safe circuits lead into explosion hazar-
dous areas subject to dust hazards, i.e. zones 0 and 1 or
20 and 21, it must be ensured that the devices which are
to be connected to these circuits, meet the requirements
of category 1GD or 2GD and feature an according
approval.
When interconnecting devices i.e. connecting intrinsically
save circuits to other circuits, it is required to keep and
provide a proof of intrinsic safety (EN 60079-14, chap.
12.2.5).
Once that intrinsically safe circuits have been connected to
the non-intrinsically safe circuit, it is not permitted to use
the device subsequently as intrinsically safe equipment.
The governing regulations cover installation of intrinsically
safe circuits, mounting to external connections, cable
characteristics and cable installation. Cables and terminals
with intrinsically safe circuits must be marked (use light
blue for coloured marking) and separated from non-
intrinsically safe circuits or feature appropriate isolation
(EN 60079-14).
Those areas of the contacts related to the intrinsically safe
circuits have to be indicated in light blue on the top side of
the device such that mismach is not possible.
Appropriate cables have to be used for wiring.
If field wireable connectors should be used together with
intrinsically save circuits, the connector ends have to be
protected with wire end sleeves (plus collar).
Please observe the specified clearances between the
intrinsically safe connections of this device and the earthed
components and connections of other devices.
The approval expires if the device is repaired, modified or
opened by a person other than the manufacturer or an ex-
pert, unless the device-specific instruction manual explicitly
permits such interventions.
Visible damages of the device’s housing (e. g. black-brown
discolouration due to heat accumulation, perforation or
deformation) indicate a serious error and the device must
be turned off immediately. When using associated appara-
tus it is required to check the connected intrinsically safe
equipment too. This inspection may only be carried out by
an expert or the manufacturer.
Operation of the devices is only permissible in accordance
with the allowed specifications which are printed on the
housing and/or listed in the documentation.
Prior to initial set-up or after every alteration of the
interconnection assembly it must be assured that the
relevant regulations, directives and framework conditions
are observed, that operation is error-free and that all safety
regulations are fulfilled. Mounting and connection of the
device may only be carried out by qualified and trained
staff familiar with the relevant national and international
regulations of explosion protection.
The most important data from the EC type examinati-
on certificate are listed on the right side. All valid national
and international approvals covering Turck devices are
obtainable via the Internet (www.turck.com). Further infor-
mation on explosion protection is available on request.
