processes
Installation, assembly, start-up and maintenance may only be performed by appropriately trained personnel. Check
the nameplate for correct operating conditions.
This instrument complies with requirements of Low Voltage Directive. Instruments must not be connected to power
supply before reading instructions described in the manual.
This instrument complies with the requirements of Pressure Equipment Directive. Please refer to the nameplate for
operating condition limits. Instruments must not be pressurised before reading instructions described in the manual.
The responsibility as to the suitability, intended use and corrosion resistance of the used materials against the
measured fluid of this device rests solely with the operator.
For use in hazardous areas, special codes and regulations are applicable. Instruments must not be connected
to power supply before reading instructions described in the supplementary manual.
Special conditions to be observed
● For ambient and process temperatures, specific product and electrical data, see Ex manual or certificate.
● For dimensions and details of the flameproof joints, the manufacturer shall be contacted.
● The tensile strength of the special fasteners is at least 700 N/mm² (property class A2-70 / A4-70).
● The instructions provided with the product shall be followed in detail to assure safe operation.
● Avoid the risk of ignition as a result of electrostatic charging. Do not use the device in areas, with processes
that generate high charges, with mechanical friction and cutting process, near electrostatic painting systems
(spraying of electrons), with exposure of airborne powder or dust particles (pressurized systems).
