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 temperature switches TS and TSE are
manufactured according to the guideline 2014/34/EU
and are intended, among other things, for controlling the
temperature of enclosures or cabinets.
The type TS is installed in the connection line of the
radiator at the factory (standard version).
The type TSE is supplied with its own connection line
and must be attached to the radiator with spacing rollers.
Both versions are approved in Ex zone 1 and zone 2 for
device categories G/ D, in temperature class T6.
EC Equipment Type Examination Number: PTB 03

5 Installation
NOTICE
Risk of Damage
When removing from the packaging and during
transport, the connection line must not be stressed or
bent.
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.
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.
INFO
The temperature switch must be installed in a housing
that meets the requirements in accordance with EN
60079-0:2009 section1.
For example:
The TSE must be connected to the radiator using the
fastening screws supplied in order to utilise its
equipotential bonding and the thermal feedback.
It must be switched electrically in series with the radiator
in an Ex e junction box.
6 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.
A 10-A fuse according to IEC 60127-2-1 or a motor
protection switch with short-circuit and thermal
instantaneous release must be upstream of each
temperature switch as short-circuit protection (setting to
10 A). The fuse or motor protection switch can be
housed in the corresponding power supply unit or must
be housed separately upstream. The fuse rated current
must be the same as or greater than the maximum value
of the specified rated voltage (normally UN+10%) of the
magnet. The breaking capacity of the fuse link must be
the same as or greater than the maximum short-circuit
current expected at the place of installation (normally
1500 A).
NOTICE
Danger of overheating
The ambient temperature range of the temperature
switch must not exceed -60°C and +80°C in operation.
NOTICE
Risk of Damage
The temperature switch and its connection line (cable
extension) must be set up in such a way that they are
protected sufficiently against mechanical damage.
The connection line of the temperature switch must be
connected in a housing that complies with the
requirements of an approved type of protection in
accordance with EN 60079-0:2009 section 1 if
connected in a potentially explosive atmosphere.
The equipotential bonding or earthing must be ensured
by installing the temperature switch on the entire system.
The temperature switch must be installed in an
additional housing that meets the requirements in
accordance with EN 60079-0:2009.
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

INTERTEC-Hess GmbH · Raffineriestr. 8 · 93333 Neustadt/Donau · Germany · [phone] · [email protected]
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 DIN EN 60079-14; section 7.4).

7 Commissioning
When installing with TS:
The temperature switch is connected directly to the
radiator.
When installing with TSE:
The temperature switch is screwed onto the radiator.
If the radiator and temperature switch is installed and
secured in accordance with the guidelines specified in
section Installation [}Page4] and Connection [}Page4],
then the radiator may be switched on.
NOTICE
Deviation of the switching point due to
incorrect installation
The ambient air must be able to circulate freely around
the thermostat. An installation at or near to the housing
wall results in a deviation of the switching point.
8 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 EN
60079-17 and EN 60079-19 must be complied with.
9 Troubleshooting
In case of a fault, first check the function of the
downstream operating equipment.
The fault is caused by the temperature switch:
Fault Cause Effect/Measure

continuously
Temperature
switch (power
circuit) is closed
permanently
Check
installation,
continuity test of
the power circuit.
Note the

10 Safety information
CAUTION
Risk of injury at the rib ends
The sharp edges on the heating ribs may cause injury if
handled incorrectly.
CAUTION
Risk of burns from a hot surface
Attainable highest temperatures:
- Max. 160°C with T3 heating systems
- Max. 100°C with T4 heating systems
- Max. 70°C with T5 heating systems
- Max. 50°C with T6 heating systems
Do not touch device during operation! Before working on
the device, allow it to cool down first.
11 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.
12 Disposal
Disassemble the components of the product, taking the
applicable local labour protection and environmental
regulations into consideration and make sure that the
components 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
disposed of incorrectly!
Electrical scrap and electronics components are subject
to hazardous waste treatment and must only be
disposed of by certified specialists!
The local community authorities or specialist waste
disposal companies can provide information on
environmentally friendly disposal.
