3.1 Explanation of symbols
WARNING!
... indicates a potentially dangerous situation that can result in serious injury or death, if not avoided.
CAUTION!
... indicates a potentially dangerous situation that can result in light injuries or damage to property or the
environment, if not avoided.
Information
... points out useful tips, recommendations and information for ecient and trouble-free operation.
3.2 Intended use
The pressure transmitter is used for measuring pressure.The measured pressure is output as an electrical signal.
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, it can interfere with other equipment under certain conditions. In such
circumstances the operator is expected to take the appropriate measures.
Only use the pressure transmitter in applications that lie within its technical performance limits (e.g. max. ambient
temperature, material compatibility, ...).
→ For performance limits see chapter 9 “Specications”.
This instrument is not permitted to be used in hazardous areas!
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.

5.2 Connecting the instrument to the electric system
5.2.1 Requirements for voltage supply
→ For supply voltage see product label
For instruments without UL approval:
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 dierent protective measure in accordance with IEC 60364-4-41
installation standard.
For instruments with UL approval and for use in North America:
The power supply for the pressure transmitter must be made via an energy-limited electric circuit in accordance with
section 9.4 of UL/EN/IEC 61010-1 or LPS per UL/EN/IEC 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.
5.2.2 Requirements for electrical connection
■
Ingress protection of the mating connector corresponds to the ingress protection of the pressure transmitter.
■
Cable diameter matches the cable bushing of the mating connector.
■
Cable gland and seals of the mating connector are correctly seated.
■
No humidity can ingress at the cable end.
5.2.3 Requirement for shielding and grounding
The pressure transmitter must be grounded via the process connection.
When working during a running process operation, measures to prevent electrostatic discharge on the connection
terminals should be taken, as a discharge could lead to temporary corruption of the measured value.
Connecting the instrument
1. Assemble the mating connector or cable outlet.
→ For pin assignments see product label
2
.
Establish the plug connection.
