1 General
These operating instructions describe the safe and
proper way to work with the device. The safety informa-
tion 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 instru-
ment 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 from Ministry of Employment and Labor No.
2016-54 and are licensed for direct heating through
flange-mounting (conduction) or for room heating (con-
vection) in Ex-zone 1 and Zone 2 for instrument categor-
ies G/ D in temperature classes T3 to T6. You will find
the temperature class for your device on the label. See
Technical Data section.
The areas of application are:
• Frost protection
• Condensation protection
• Maintaining temperature
As an option, thermostats can be integrated in the con-
necting cable. If a TAE is used, the respective operating
instructions must be complied with.
Product approval 18-KA4BO-0092X and 18-
KA4BO-0091X with appendices and supplements, as
well as IEC Scheme Certificate IECEX PTB 07.0055X.

7 Installation
NOTICE
Carefully remove
When removing from the packaging and during trans-
port, the connection line must not be stressed or bent.
Free convection may not be impeded. You will find the
minimum distances and installation position in the follow-
ing figure.
The label needs to remain legible.
Please make sure that the absolute heat transfer coeffi-
cient 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 per-
missible bending radius = 5 x outer diameter into consid-
eration.

Illustration1: Installation example MEGATHERM with TS or
TAE and 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 [}Page4])
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 pre-
ceded 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 in-
tegrated thermostat, the fuse protection can be selected
according to the cross-section of the supply cable.
Additional equipotential bonding is required. The ter-
minal block designated for this purpose has the ground
sign.
ATTENTION:
Never remove the
adapter/ cable gland!
Illustration2: Example heater with KLE connection
CAUTION
NOTICE: Do not remove adapter/ cable connec-
tion 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 commis-
sioned.
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 in-
stallation instructions are not adhered to.
10 Maintenance
The design of the device does not require any mainten-
ance.

Functional and safety test intervals can be freely selec-
ted 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 KS C
IEC 60079-17 must be complied with.
11 Troubleshooting
If the heater fails, check the installation. Carry out a con-
tinuity test on the heating circuit. Pay attention to the
connection diagram and switching point of the thermo-
stat!
12 Deinstallation
Disassembly may only be carried out by a trained per-
son.
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
Disassemble the components of the product, taking the
applicable local labour protection and environmental reg-
ulations into consideration and make sure that the com-
ponents are recycled:
• Scrap metal
• Send plastic elements to recycling
• Sort other components according to their material
properties and dispose of them.
NOTICE
Environmental damage may be caused if dis-
posed of incorrectly!
Electrical scrap and electronics components are subject
