2. Safety
WARNING!
Before installation, commissioning and operation, ensure
that the appropriate switch has been selected in terms
of switching temperature, design and specic measuring
conditions.
Non-observance can result in serious injury and/or
damage to the equipment.
Further important safety instructions can be found in the
individual chapters of these operating instructions.
2.1 Intended use
The model TFS135 bimetal temperature switches are used to limit
temperatures within a wide variety of industries.
The TFS135 are temperature limiting instruments.They are not
intended to provide any safety or protective functionality.
They monitor the temperature of machinery and equipment during
normal operation and, for example, switch o machinery if it
overheats.
The instrument has been designed and built solely for the intended
use described here, and may only be used accordingly.
The technical specications contained in these operating instructions
must be observed. Improper handling or operation of the bimetal
temperature switch outside of its technical specications requires the
instrument to be taken out of service immediately and inspected by
an authorised WIKA service engineer.
The manufacturer shall not be liable for claims of any type based on
operation contrary to the intended use.

2. Safety
2.2 Personnel qualication
WARNING!
Risk of injury should qualication be insucient!
Improper handling can result in considerable injury and
damage to equipment.
■
The activities described in these operating instructions
may only be carried out by skilled personnel who have
the qualications described below.
■
Keep unqualied personnel away from hazardous
areas.
Skilled personnel
Skilled personnel are understood to be personnel who, based on
their technical training, knowledge of measurement and control
technology and on their experience and knowledge of country-
specic regulations, current standards and directives, are capable
of carrying out the work described and independently recognising
potential hazards.
Special operating conditions require further appropriate knowledge,
e.g. of aggressive media.
2.3 Special hazards
WARNING!
For hazardous media such as oxygen, acetylene,
ammable or toxic gases or liquids, and refrigeration
plants, compressors, etc., in addition to all standard
regulations, the appropriate existing codes or regulations
must also be followed.

2. Safety
WARNING!
To ensure safe working on the instrument, the operating
company must ensure
■
that suitable rst-aid equipment is available and aid is
provided whenever required.
■
that the operating personnel are regularly instructed
in all topics regarding work safety, rst aid and
environmental protection and know the operating
instructions and in particular, the safety instructions
contained therein.
DANGER!
Danger of death caused by electric current
Upon contact with live parts, there is a direct danger of
death.
■
The instrument may only be installed and mounted by
skilled personnel.
■
Any connection work may only be carried out once the
equipment has been isolated.
■
Operation using a defective power supply unit (e.g.
short circuit from the mains voltage to the output
voltage) can result in life-threatening voltages at the
bimetal temperature switch!
WARNING!
Residual media in the dismounted instrument can result
in a risk to persons, the environment and equipment.Take
sucient precautionary measures.
Do not use this instrument in safety or emergency stop
devices. Incorrect use of the instrument can result in
injury.
Should a failure occur, aggressive media with extremely
high temperature and under high pressure or vacuum
may be present at the instrument.

5. Transport, packaging and storage
5. Transport, packaging and storage
5.1 Transport
Check the bimetal temperature switch for any damage that may
have been caused by transport. Obvious damage must be reported
immediately.
5.2 Packaging
Do not remove packaging until just before mounting.
Keep the packaging as it will provide optimum protection during
transport (e.g. change in installation site, sending for repair).
5.3 Storage
Permissible conditions at the place of storage:
■
Storage temperature: -40 ... +85 °C
■
Humidity: 35 ... 85 % relative humidity (no condensation)
Avoidance of exposure to the following factors:
■
Direct sunlight or proximity to hot objects
■
Mechanical vibration, mechanical shock (putting it down hard)
■
Soot, vapour, dust and corrosive gases
■
Potentially explosive environments, ammable atmospheres
Store the bimetal temperature switch in its original packaging in
a location that fulls the conditions listed above. If the original
packaging is not available, pack and store the temperature switch as
described below:
1. Wrap the temperature switch in an antistatic plastic lm.
2. Place the temperature switch, along with shock-absorbent material,
in the packaging.
3. If stored for a prolonged period of time (more than 30 days), place a
bag containing a desiccant inside the packaging.

5. Transport ... / 6. Commissioning, operation
WARNING!
Before storing the temperature switch (following
operation), remove any residual media.This is of
particular importance if the medium is hazardous to
health, e.g. caustic, toxic, carcinogenic, radioactive, etc.
6. Commissioning, operation
6.1 Mounting
When the temperature switch is mounted, the temperature must
neither drop below the allowed operating temperature (environment,
medium) nor exceed it, even when taking convection and heat
radiation into account.
Depending on the type of application, the electrical connection must
be protected from mechanical damage.
6.2 Electrical connection
WARNING!
Only connect with power disconnected!
Only disconnect the mating connector with the voltage
disconnected. Use suitable mating connectors for the
current and voltage ranges.
Cables and wires
■
Leads with bare ends must be nished with end splices.
■
Cables used must comply with the respective requirements in
terms of stability and temperature.
■
Connecting cables must be run so that any mechanical damage is
prevented.
■
Only connect circuits with the same voltage and type of protection
to the switch contacts and connecting cables.
■
Size the connecting cables for the largest current strength in the
circuits.

6. Commissioning, operation
Voltages > AC 50 V or DC 75 V
■
The TFS135 must be connected to the system of the protective
earthing of the end product or the end application via the process
connection.
■
Circuits must oer a device, external to the measuring instrument,
that enables the instrument to be isolated from the electrical
supply.This must be easily accessible and be marked as the
isolation device for the instrument.
■
Cables and circuits must full the isolation requirements and
conform to, for example, IEC 60227 or IEC 60245.
■
Do not connect circuits simultaneously with extra-low voltage
circuits, or with safety extra-low voltage circuits (SELV) or
protected extra-low voltage circuits (PELV).
6.3 Pin assignment
WARNING!
The earthing terminal is not connected and therefore it
does not provide electrical connection to protective earth.
