3.1 Explanation of symbols and terms
WARNING!
The signal word indicates a hazard with a medium degree of risk which, if not avoided, may result in
death or serious injury.
CAUTION!
The signal word indicates a hazard with a low degree of risk which, if not avoided, may result in minor
or moderate injury.
Information
The signal word points out useful tips, recommendations and information for ecient and trouble-free
operation.
3.2 Intended use
The model A-10 is a pressure transmitter that is used for pressure measurement in general industrial applications.The
pressure transmitter may only be used in such applications as are within its technical performance limits, in particular
with regard to its material resistance limit, leakage rate limits and permissible temperature and pressure limits.
It is the sole responsibility of the manufacturer or operator of a machine or plant to ensure the suitability of the pressure
transmitter, and its media resistance, within the application through proper choice of materials and maintenance cycles.
(For performance limits, see chapter 8 "Specications")
The mounting, dismounting, installation, parameterisation and maintenance of the pressure transmitter in industrial
environments absolutely requires suitably skilled personnel in accordance with chapter 3.4 "Personnel qualication".
This is a class B instrument for emissions and is intended for use in industrial environments. In other environments, e.g.
residential or commercial installations, such instruments can interfere with other equipment under certain conditions. In
such circumstances the operator is expected to take the appropriate measures.
The instrument has been designed and built solely for the intended use described here, and may only be used
accordingly.
The manufacturer shall not be liable for claims of any type based on operation contrary to the intended use.

3. Safety
3.3 Improper use
Any use beyond or dierent to the intended use is considered as improper use. Unauthorised modications to the
instrument are not permissible.
Use in the following application areas counts as improper use:
■Safety or emergency shutdown devices
■Hazardous areas
■Abrasive or viscous media and applications with hydrogen and oxygen
■Rail vehicles, medical devices and refrigeration technology
■Places of use that are not protected from weather inuences
■Processes with high condensation
3.4 Personnel qualification
Skilled personnel
Skilled personnel, authorised by the operator, 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-specic
regulations, current standards and directives, must be capable of carrying out the work described and independently
recognising potential hazards.

3. Safety / 4. Mounting
Before mounting and commissioning the instrument, ensure you read the operating instructions!
DC voltage
Do not dispose of with household waste. Ensure a proper disposal in accordance with national
regulations.
4. Mounting
4.1 Mechanical mounting
Only use the pressure transmitter if it is in perfect condition with respect to safety.
Prior to commissioning, the pressure transmitter must be subjected to a visual inspection.
■Leaking liquid is indicative of damage.
■Obvious damage must be reported immediately.
For information on tapped holes and welding sockets, see technical information IN 00.14 at www.wika.com.
4.2 Electrical mounting
Voltage supply
→For auxiliary power, see product label
→For further details on electrical mounting, see IN 00.50
ForinstrumentswithoutNorthAmericancertication:
This equipment is intended for operation with low voltages, which are separated from the AC 230 V (50 Hz) mains
voltage or voltages greater than AC 50 V or DC 120 V for dry environments. A connection to an SELV circuit is
recommended, or alternatively to circuits with a dierent protective measure in accordance with IEC 60364-4-41
installation standard.

4. Mounting / 5. Faults
ForinstrumentswithNorthAmericancerticationperUL/CSAIEC61010-1:
The power supply for the pressure transmitter must be made via a limited-energy circuit in accordance with section 9.4
of UL/IEC/EN 61010-1, or an LPS in accordance with UL/IEC/EN 60950-1/CSA C22.2 no.60950-1 or class 2 per
UL1310/UL1585 (NEC or CEC). The voltage supply must be suitable for operation above 2,000 m should the pressure
transmitter be used at this altitude.
Shielding and grounding
Include the pressure transmitter in the equipotential bonding via the process connection or connect it to ground (earth).
Pin assignment
→For pin assignments, see product label
5. Faults
CAUTION!
Physical injuries and damage to property and the environment
If faults cannot be eliminated by means of the listed measures, the pressure transmitter must be taken
out of operation immediately.
▶Ensure that pressure or signal is no longer present and protect against accidental commissioning.
▶Contact the manufacturer.
▶If a return is needed, please follow the instructions given in chapter 7.2 "Return".
For contact details, see chapter 1 “General information” or the back page of the operating instructions.
In the event of any faults, rst check whether the pressure transmitter is mounted correctly, mechanically and
electrically.
Faults Causes Measures
No output signal Cable break Check the continuity
Deviating zero point signal Overpressure limit exceeded Maintain permissible overpressure limit

Faults Causes Measures
Deviating zero point signal Too high/low temperature of use Observe the permissible temperatures
Constant output signal upon change
in pressure
Mechanical overload caused by
overpressure
Replace instrument; if it fails repeatedly,
contact the manufacturer
Signal span varies EMC interference sources in the
environment, e.g., frequency converter
Use shielded cable; remove source of
interference
Signal span varies/inaccurate Too high/low temperature of use Observe the permissible temperatures
Signal span drops/too small Mechanical overload caused by
overpressure
