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.

Operating Instructions SL FLATTHERM DC.A
HOM2540404619Ien-0 Page 5 / 11
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.
Illustration2: 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.
ATTENTION:
Never remove the
adapter/ cable gland!
Illustration3: Example heater with KLE connection
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.
The illustration may deviate from the heater.

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.

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!

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.
13 Disposal
