1 General
These operating instructions describe the safe and
proper way to work with the device. The safety
information and instructions given as well as the local
accident prevention regulations and general safety
regulations valid in the area of application must be
complied with. These instructions are a constituent part
of the instrument and need to be kept in the immediate
vicinity of the device accessible to personnel at all times.
Before starting any work, the operating instructions
should be read in full.
2 Use
The SL..THERM heaters are manufactured according to
Directive INMETRO No. 115, of March 21st, 2022 and
are licensed for direct heating through flange-mounting
(conduction) or for room heating (convection) in Ex-zone
1 and Zone 2 for instrument categories G/ D in
temperature classes T3 to T6. You will find the
temperature class for your device on the label. See
Technical Data [}Page4] section.
The areas of application are:
• Frost protection
• Condensation protection
• Maintaining temperature
As an option, thermostats can be integrated in the
connecting cable. If a TAE is used, the respective
operating instructions must be complied with.
Product approval NCC 17.0104 X with appendices and
supplements, as well as IEC Scheme Certificate IECEX
PTB 07.0055X.
See http://www.intertec.info
3 Special conditions for safe use
1. The heater may only be installed and operated in
enclosures whose absolute heat transfer coefficient
is not less (not better) than 0,5 W/K.
2. The connecting cable must have a fixed installation
and must be protected mechanically.
3. If connection is made in the potentially explosive
area, the connecting lead shall be connected by
means of an enclosure that meets the requirements
of a type of protection specified in ABNT NBR IEC
60079-0.
4. Installation shall be made with due regard to the
maximum permissible temperatures of neighbouring
components, the minimum clearances and, where
required, the mounting position.
5. Additional conditions for alternate use of thermostats
see concerning test certificate. They have to be
separately certified to the same standards.
6. Special conditions for some connecting cables have
to be included in the operating manual and have to
be noticed by the installer.
7. lf used in dust-ex-areas the concerning requirements
of ABNT NBR IEC 60079-14, of ABNT NBR IEC
60079-17 and ABNT NBR IEC 60079-19 have to be
considered.
4 Explanation of symbols for warnings

7 Installation
NOTICE
Carefully remove
When removing from the packaging and during
transport, the connection line must not be stressed or
bent.
To optimally route the heat, the FLATTHERM should be
mounted if possible in full surface contact on a metal
surface. The boreholes required for this can be placed
individually. Please keep the necessary safety distance
from the profile core. Refer to the following drawing.
The label needs to remain legible.
The label needs to remain legible.
Please make sure that the absolute heat transfer
coefficient of the surrounding housing is not smaller than
0.5 W/K.
To ensure operational safety, the heater must operate
under temperature conditions which will NOT exceed the
trigger temperature of the limiter.
The operating temperatures must be adhered to.

The connection cable must be permanently installed up
to the inlet into the on-site junction box, taking the
permissible bending radius = 5 x outer diameter into
consideration.
In the dust Ex area, the applicable requirements of
ABNT NBR IEC 60079-14 must be complied with.
Illustration2: Installation example FLATTHERM with TS and
with clearance
Additional installation material, such as rails or panels
and also junction boxes, are not included in the standard
scope of delivery (see Installation accessories) and must
be ordered additionally.
8 Connection
INFO
The device may only be connected up and secured by a
trained person, taking into account the "rated voltage"
and "rated current" specified on the nameplate.
Where operating voltage = measured voltage (rated
voltage), then the heater is at its rated output. Mains
voltage fluctuations up to 10 % are then permissible.
Each heater with integrated TS thermostat must be
preceded by a 10 A fuse or a motor protection switch
with short-circuit and thermal quick release (set to 10 A)
as short-circuit protection. When using a heater without
integrated thermostat, the fuse protection can be
selected according to the cross-section of the supply
cable.
Additional equipotential bonding is required. The
terminal block designated for this purpose has the
ground sign.
In a TT or TN system, a residual current device (RCD)
must be used where the measured triggering residual
current does not exceed 100 mA. Residual current
devices with a measured triggering residual current of 30
mA are preferable. In an IT system, an insulation
monitoring device needs to be used which switches off
the supply as soon as the insulation resistance is no
greater than 50 Ω per Volt of the rated voltage (refer also
to ABNT NBR IEC 60079-14:2009).
ATTENTION:
Never remove the
adapter/ cable gland!

CAUTION
NOTICE: Do not remove adapter/ cable
connection to connect up the heater!
This would cause irreversible damage to the heater and
this would mean that the explosion protection can no
longer be warranted.

9 Commissioning
If the heater is installed in accordance with the notes in
the Installation [}Page 4] section and Connection [}
Page 5] sections, then the radiator may be
commissioned.
CAUTION
Sufficient heat dissipation must be ensured.
Unauthorized covers must be removed as otherwise
there is the risk of the heater overheating.
The heating circuit is permanently disconnected by a
temperature melt fuse which can't be reset if these
installation instructions are not adhered to.
10 Maintenance
The design of the device does not require any
maintenance.

Functional and safety test intervals can be freely
selected by the operator in accordance with the
applicable regulations.
Repairs may only be carried out by the manufacturer in
the factory.
All components have to be kept clean and free of dust
and harmful substances that could lead to excessive
temperature rise.
In the dust Ex area, the applicable requirements of
ABNT NBR IEC 60079-17 and ABNT NBR IEC
60079-19 must be complied with.
11 Troubleshooting
If the heater fails, check the installation. Carry out a
continuity test on the heating circuit. Pay attention to the
connection diagram and switching point of the
thermostat!
12 Deinstallation
Disassembly may only be carried out by a trained
person.
DANGER
Risk of fatal injury from electric current!
If contact is made with live components, there is the risk
of fatal injury.
For this reason, switch off the voltage supply, secure
against being switched on again and check that no more
voltage is present.
Disconnect connection line from the clamps and from the
connection socket, disconnect device from bracket and
remove it.
