The product is fully assembled, and ready for installation.
SAFETY PRECAUTIONS
SPECIAL CONDITION FOR SAFE USE
Tranberg heaters type TEF 9202 are not suitable for use in
Zone 0 hazardous areas. Changes made to the product not
conforming to the certificate, or failing to use the product
according to the user manual and relevant regulations
may lead to a fire or explosion risk, as well as risk of
overheating of equipment, burns and electric shock. The
manufacturer is under no circumstances responsible for
any injury or damage caused by such activities.
Installation, testing and maintenance shall be performed
by qualified personnel. Equipment shall be securely
disconnected from voltage elsewhere before any install,
testing or maintenance activities are performed on the
heater.
INSTALLATION INSTRUCTION
Only qualified personnel are allowed to perform installation
and maintenance tasks to this product.
The enclosure heater is ready for installation when leaving
the production facilities of Tranberg AS. If the content has
any defects or is not complete, file a claim to the manufac-
turer immediately.
Mounting:
The 9202 Enclosure Heater must be mounted and fastened
through mounting holes at rear side of heater by means of
M5 screws/bolts. All screws must be firmly tightened to se-
cure the heater. All measures for mounting are shown ion
the last page of this manual.
Special conditions for safe use (as stated in the rel-
evant certificates):
• The heaters with permanently connected unterminat-
ed flying lead cable need an appropriate protection of
the free end of the cable (for example terminated in an
Ex e junction box).
• The heaters with thermostat shall be connected to
a circuit breaker with rated current max. 16A and a
breaking capacity of min. 1500A.
• The supply circuit shall include an electrical protection
device according to IEC/EN 60079-30-1 CL 4.3
• Enclosure heaters of type TEF9206, 9208, 9209 and
TEF 9202 0XX shall be installed inside an enclosure
with IP min. IP66 (this clause is not applicable for TEF
9207 and TEF 9202 2XX).
Additional Conditions for heaters type TEF 9202:
• Potential electrostatic charging hazard – For cleaning
use mist cloth only! No solvent.
• If DIN-rail bracket is used for mounting on a rail, this
shall be earthed.
Tranberg heaters type
TEF 9202 hold the following certificates:
ATEX: Presafe 18ATEX12634X
IECEx: IECEx PRE 18.0037X
The certificates are issued in based on the following
standards:
EN 60079-0:2012/A11:2013
EN 60079-7:2015
EN 60079-18:2015
EN 60079-30-1:2007
IEC 60079-0:2011
IEC 60079-7:2015
IEC 60079-18:2014
IEC 60079-30-1:2007
APPROVALS & CERTIFICATES
INSTALLATION REQUIREMENTS
The heater supply circuit shall be protected against earth
fault and short circuit currents in accordance with IEC/EN
60079-30-1 (For version 2015/2017 clause 4.3). For heaters
without thermostat, the circuit breaker shall be selected to
fit the installation and sufficiently protect the “flying lead”
2,5mm² cable in the heater.
When the heater is not installed inside a certified hazardous
area enclosure (for example Ex p, Ex e, Ex d etc.) the flying
lead cable shall be protected from mechanical damage.
The TEF 9202 heater series shall only be used inside a
certified hazardous area enclosure with IP min. IP54. The
TEF 9202 heater series are suitable for use in any enclosed
space (room, skid, uncertified enclosure, container, storage
cabinet etc.). The use of heaters in open air is not recom-
mended. If internal procedures demand isolation/dielectric
testing of the heaters, this should be done with DC voltage
of max 2550V DC.
DISPOSAL
The heaters shall be disposed of according to company
and national regulations. The heaters are considered elec-
trical equipment waste (EE waste).

Electrical connection:
Connect to 220-240V AC 50/60 Hz
Reliability:
Because of the intrinsic self-regulating properties of the
heater, the heater can be used without a thermostat. This
provides, in a single component, a heater that is not vulner-
able to thermostat failure.
Further, the rugged polymer construction of the heater ele-
ment ensures highly reliable performance in harsh and cor-
rosive environments due to the composite housing.
Design flexibility:
Due to the relatively low surface temperature and self-regulat-
ing nature of the heater, components and wires may be lo-
cated close to the heater without fear of damage caused by
overheating. The relatively low profile of the heater makes it
ideal for installation into a range of control and monitoring
panels as well as instrumentation and monitoring cabinets
located on-site.
INSTALLATION INSTRUCTION
Operation:
The Tranberg 9202 Enclosure Heater contains no moving
parts. It may be left without fear of failure through overheat-
ing. The heater may be installed anywhere in the enclosure,
although, for best result, the heater should be mounted to-
wards the base of the enclosure in a horizontal position.
Self-regulating performance:
The enclosure heater contains an element consisting of a
semi-conductive polymer core extruded between two par-
allel copper conductors. This leads to a higher heat-output
at low temperatures, with the power decreasing as the tem-
perature increases. This may help to prevent overheating of
enclosures and components.
Maintenance/Repairs/Modification:
Before disconnecting the heater, make sure that the power
is disconnected. If the enclosure heater failed and is defect,
it should be replaced by a new heater. Modification of the
enclosure heater or change of design is not allowed.
4xM5 mounting holes on the
backside of the heater.
Hold the heater close to the installation
surface, and insert the M5 screws in each
of the 4 mounting holes. Use a tool to tighten the screws firmly and secur-
ing the heater.
Mounting with screws
After properly fasten-
ing the DIN rail
beneath the heater,
slide the DIN rail onto
the SS35/15 terminal
rail.
Mounting on SS35/7,5 terminal rail
After properly fasten-
ing the DIN rail
beneath the heater,
click the DIN rail onto
the SS35/15 terminal
rail.
