1.6 Operating safety information
Before switching on, ensure that the specified environmental conditions in the “Technical
Specifications” chapter and/or in the data sheet are complied with and that the power supply
voltage corresponds with the voltage of the transmitter.
When there is a chance that safe operation is no longer possible, put the device out of operation
and secure against unintended operation.
2 Use in areas requiring ignition protection
Caution – Damage to parts!
The installation must be performed according to the manufacturer requirements and the valid
norms and regulations for it.
The commissioning and operation must be performed according to the ATEX 137 or
BetrSichV (Operational safety regulation), EN60079-14 (Electrical apparatus for explosive gas
atmospheres. Electrical installations in hazardous areas (other than mines)) and EN50281-1-2
and 2/A1 (Electrical apparatus for use in the presence of combustible dust).
2.1 Degree of protection
The connection parts of the temperature sensor are to be installed so that at least the minimum
degree of protection of the explosion protection used is reached.
2.2 Temperature classes
The temperature sensors are designated with the T6 temperature class. If the existing explosive
gas atmosphere is assigned a temperature class of T5, T4, T3, T2, or T1, the temperature
sensor can be used at correspondingly higher process temperatures.
2.3 Electrostatic charging
For use in explosion risk areas, attention must be paid so that an unallowable electrostatic
charging of the temperature sensor is avoided.
2.4 Ground connection
If the intrinsically safe circuit has to be grounded to the potential equalization for functional
reasons, this may only be grounded at one point.
2.5 Interconnection
If the temperature sensor is operated in an intrinsically safe circuit, a certificate according to DIN
VDE 0165/08.98 (=EN 60 079-14/1997 as well as IEC 60 079-14/1996) about the intrinsic safety
of the interconnection is to be provided. An interconnection certificate for intrinsically safe
electrical circuits is to be produced.

best possible contact with the medium to be measured.
• The connection lines must be firmly connected with the connection terminals.
• Observe the correct polarity for thermocouples.
• Observe the protection type for 2-wire, 3-wire, or 4-wire connection.
• When installing in thermowell, observe that the temperature sensor can be moved slightly. If
this is not the case, the inside of the thermowell must be cleaned.
• The diameter of the connection lines must be selected according to the cable entry points on
the connection head.
• The temperature sensor must be firmly and securely installed according to the application
process.
• Observe the specified protection type. (single or double measuing insets 2-wire, 3-wire, or 4-
wire connection)
• After clamping the connection lines using a suitable tool (screwdriver, wrench), ensure that
the connection heads are securely closed and sealed. Be sure to observe here that the
sealing rings of the connection head are clean and undamaged.
Installation
CI/TSP-EN SensyTemp TSP EN - 7
3.2 Insertion depth
The insertion depth of a temperature sensor can affect the accuracy of measurements:
Improper sensor installation can result in measurement errors due to heat dissipation from the
process connection and the tube or tank wall. (The size of the error depends on ambient
conditions at the measuring point.)
Recommended insertion depth (to avoid heat dissipation errors)
Medium Depth [mm]
Fluids 8 to 10 x Ø thermowell tip
Gases 10 to 15 x Ø thermowell tip
Fig. 1
3.3 Insufficient mounting diameter
For pipes with very small nominal diameters, an oblique insertion or insertion in an elbow pipe is
recommended; whereby the thermowell tip must be positioned against the flow of the medium.

4 Electrical connection
4.1 General
Observe the corresponding instructions for the electrical installation. Only connect in dead-
voltage state!
Since the sensor and transmitter have no switch-off elements, overvoltage protection devices,
lightning protection or voltage separation capacity must be provided on the plant side.
The following applies to devices with a transmitter: Energy supply and signal are routed in the
same line and are to be implemented as SELV or PELV circuit according to norm (standard
version).
In the ignition-proof version, the guidelines according to the ignition-proof norms are to be
adhered to. It must be checked whether the existing power supply corresponds with the
specifications on the model plate and in the technical specifications (see chapter “Technical
specifications” and/or data sheet).
Note
The electrical connection is carried out with the temperature sensor/transmitter in the installed
state.
The signal cable wires must be provided with wire end sleeves.
The maximum connectable conductor cross-section amounts to 1.5 mm
2
(AWG14). The cross-
head screws of the connection terminals are tightened with a size 1 screwdriver (3.5 mm or 4
mm). Observe the diameter of the selected cable gland. (See the installation chapter).
4.1.1 Cables and wires
• Only use isolated cables and wires whose tested voltage between wire - ground, wire -
shielding and shielding - ground amounts to at least 500 V AC.
• Use wire end sleeves for fine-wire wires.
• The cables used must fulfill the valid requirements with regards to strength and temperature
for the particular application case.
• The electrical connection wires must be run so that mechanical damage is impossible.
• For the use of PROFIBUS, the running of the wires is performed according to EN 50 170 for
PROFIBUS PA.
• For the use of FOUNDATION Fieldbus the running of the wires is performed according to
IEC61158.
4.1.2 Electrical connection in explosion risk area

4.1.2.1 Electrical interconnection in explosion risk area
Special interconnections are required for use in hazardous areas depending on the safety
requirements.
Intrinsic safety
The feed separator / SPS inputs must have corresponding input protection circuits available in
order to eliminate a hazard (spark formation). An interconnection inspection must be performed.
For proof of the intrinsic safety, the electrical limit values are to be used as the basis for the
prototype test certificates of the apparatuses (devices), including capacitance and inductivity
values of the wires. The proof of the intrinsic safety is given if the following conditions are
fulfilled with comparison of the limit values of the aparatus.

Electrical connection
CI/TSP-EN SensyTemp TSP EN - 13
4.1.3 EMC suitable cabling
The power supply of the transmitter occurs via the signal cable. A shielding of the cable is not
mandatory for analog transmitters, however, shielded and twisted wires achieve the best
results. For shielded cables, the shielding must be included in the potential equalization within
and outside of the explosion risk area. Unshielded cables may not be run in the area of strong
electrical fields.
For fieldbus applications (PROFIBUS PA, FOUNDATION Fieldbus), the corresponding
instrumentation guidelines for an EMC suitable cabling must be taken into account (e.g.
PROFIBUS PA instrumentation guidelines from the PNO).
4.1.4 Terminal connection
1. The power supply should be securely switched off when making electrical connections.
2. Open the connection head. The connection head may not be opened in an explosive
environment if voltage is present. Observe the cool down time!
3. Connect the positive wire with the terminal on the transmitter labeled with the “+” and the
negative wire with the terminal labeled with the “-“. The use of terminal ends (lugs) is
recommended.
4. Establish a ground connection if necessary. Observe the Ex norms for a safe ground
connection.
5. The screws must be tight and a good contact must be ensured.
6. The connection head must be tightly closed (see installation chapter) in order to comply with
the explosion protection requirements. Depending on the explosion protection type, only
approved cable glands may be used.
4.1.5 Protection types
Thermocouples can be used as single or double thermocouples. Resistance thermometers can
be used in 2-, 3-, or 4-wire connection. Only one measurement circuit may be connected for the
protection type EEx i for double measurement elements (z.B. 2 x Pt100). ABB transmitters are
internally switched so that 2 measurement elements may also be connected since both
elements are integrated into the same EEx I sensor circuit. The maximum number of wires in
the plasic-sheathed cable is limited to 6.
Caution – Damage to parts!
The sum of the applied voltage may not exceed 30 V, the sum of the applied currents may not
exceed 32 mA.
Only certified transmitters with the maximum values specified in the instruction manual may be
connected to the temperature sensors. If two transmitters are used for two instrinsically safe
circuits, the sum of the values may not exceed the maximum values specified in the operating
instructions.
Electrical connection
14 - EN SensyTemp TSP CI/TSP-EN
4.1.6 Potential equalization
The temperature sensors must be integrated in the potential equalization of the installation
location. They may be ground isolated or connected at one location to the potential equalization
system of the instrinsically safe circuits of the installation location.
Thermocouples may be grounded if they are welded into the ground. If the temperature sensors
do not fulfill the 500 V AC voltage test, 1 minute, leakage current < 5 mA, then these
temperature sensors are labeld with "Voltage test less than 500 V". Here, a connection to
ground is to be assumed.
Fig. 4
4.1.7 Instrumentation
The power supplies and the IEC fuses for operation of the temperature sensors with and without
installed temperature transmitter must be located outside of the explosion risk area.
4.2 Temperature sensor connection without transmitter
It must be ensured with this instrumentation that the power feed occurs using an approved
intrinsically safe electrical circuit of the category EEx ia IIC or II B or via an IEC fuse with a
nominal current of ≤ 32 mA. The electrical and thermal parameters may not be exceeded, see
chapter “Thermal data“ in the operating instructions.
Note
For use of double measurement circuits (2 x Pt100, 2 x thermocouple, 2 installed transmitters
in the connection head), the sum of the voltages, currents and power may not exceed the
electrical and thermal parameters. See chapter “Thermal data“ in the operating instructions.

4.2.3 Installation in explosion risk area
The installation of the temperature sensor can be performed in most varying industrial locations.
Plants requiring explosion protection (Ex plants), are divided into zones and the most varying of
instrumentation is accordingly necessary. The explosion-relevant information according to
chapter “Explosion protection-relevant information“ in the operating instructions must be
complied with.
The temperature sensor must be instrumented by the user in accordance with the valid Ex
norms (explosion-protection). The electrical connection values must be complied with according
to the associated EC prototype test certificate.
4.2.3.1 Intrinsic safety:
ATEX II 1 G EEx ia IIC T6 ... T1, Zone 0, 1, 2
Only one measurement circuit may be connected for the protection type EEx i for double
measurement elements (e.g. 2 x Pt100). ABB transmitters are internally switched so that 2
measurement elements may also be connected since both elements are integrated into the
same EEx I sensor circuit. The maximum number of wires in the plastic-sheathed cable is
limited to 6.
Only certified transmitters with the maximum values specified in the instruction manual may be
connected to the temperature sensors. If two transmitters are used for two intrinsically safe
circuits, the sum of the values may not exceed the maximum values specified in the instruction
manual. For the Zone 0 design, only one intrinsically safe sensor measurement circuit may be
used.
The temperature sensor must have appropriate input protection circuits available in order to
eliminate a hazard (spark formation). An interconnection inspection must be performed. For
proof of the intrinsic safety, the electrical limit values are to be used as the basis for the
prototype test certificates of the apparatuses (devices), including capacitance and inductivity
values of the wires.
