SAFETY PRECAUTIONS
SPECIAL CONDITION FOR SAFE USE
1. The equipment must be protected with earth
leakage protective device or insulation monitoring
device, dependent on the type of system earth,
according to IEC 364-3, Chapter 31, CENELEC
EN 50019:2000, Annex D., and Canadian Electrical
Code, Section 62, Rule 62-300 (either as pt. 1 or
pt. 2 below):
1. A A residual current protective device with a rated
residual operating current not exceeding 300 mA
should be used. Preference should be given to
protective devices with a rated residual operating
current of 30 mA. The protective device should
have a maximum break time not exceeding 5 s
at the rated residual operating current and not
exceeding 0,15 s at 5 times the rated residual
operating current.
2. An insulation monitoring device should be used
to disconnect the supply whenever the insulation
resistance is lower than 50 Ω/ V of rated voltage.
2. A The heating unit must be terminated in a suitable
certified terminal enclosure or in safe area.
2. B The heater unit with permanently connected
unterminated cable need an appropriate protection
of the free end of the cable.
Tranberg series 9201 Enclosure Heaters are not suitable for
use in Zone 0 hazardous areas. Changes made to the product
not confirming to the approvals of this equipment, is a safety
violation. The manufacturer is under no circumstances
responsible for personal injuries, death or any other damage
caused by such activities. For replacement and repairs of
the enclosure heater only Tranberg AS spare parts shall
be used. Repairs effecting the explosion protection of
the equipment, shall only be carried out by Tranberg AS,
or qualified electricians in compliance with the respective
national regulations.
APPROVALS
Warning:
Do not disconnect the enclosure heater without dis-
connecting power supply. Only qualified personnel are
allowed to perform installation and maintenance tasks to
this product
INSTALLATION INSTRUCTION
Only qualified personnel are allowed to perform installation
and maintenance tasks to this product.
The enclosure heater may be equipped according to cus-
tomer specification, list of component and product data
sheet, and is then 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 manufacturer
immediately.
Mounting:
The 9207 Enclosure Heater must be mounted and fastened
through mounting holes at rear side of heater by means of
M6 screws/bolts. All screws must be firmly tightened to se-
cure the heater. All measures for mounting are shown in
product data/catalogue sheet.
The enclosure heater must not be tested with or
terminated to (1000+2Un) V r. m. s. (e. g. 1500 VAC), where
Un is the rated voltage. Only DC (direct current) of max.
2550 VDC is acceptable for testing of electrical insulation
resistance between lead wires and braid.

TEF 9207 Ex ENCLOSURE HEATER USER MANUAL
Junction box:
Install blind plugs in all non-used hole in junction box.
Breather / drain plug must only be installed in the longest
horizontal side of junction box.
Electrical connection:
For heater w/ junction box the heating cable is already ter-
minated to terminals inside junction box. The power cable
should be connected directly to the terminal blocks inside
junction box.
For electrical protection and special conditions related to the
electrical connection, see Technical specification on page 2.
In order to maintain the mode of protection, the conductors
must be connected with special care. The isolation must
reach up to the terminal and the conductor must not be
damaged. All screws of terminals, also those remaining va-
cant, must be tightened.
Only DC (direct current) of max. 2550 VDC is acceptable
for testing of electrical insulation resistance between lead
wires and braid.
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 acid resistance stainless
steel housing.
INSTALLATION INSTRUCTION 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.
Operation:
The Tranberg 9207 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. At low temperatures, electrical cur-
rent flows between the conductors thus generating heat. As
the temperature rises the electrical resistance of the core
material increases thus reducing current flow and heat out-
put. Power consumption in respect to the ambient tem-
perature is shown in product data/catalogue sheet.
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.
Note! Never install the heater with junction box facing
upwards. Please se datasheet for mounting details.
4xM6 mounting holes on the
backside of the heater.
Hold the heater close to the installation
surface, and insert the M6 screws in each
of the 4 mounting holes.
Use a socket wrench to tighten the screws firmly
and securing the heater.
For the “sandwich” model, insert
the M6 screws and a washer in the
mounting brackets as shown. Use
a wrench for tightening the screws
firmly.
Bonding to earth.
