4 Mounting4.1 General instructionsMake sure that all parts of the instrument exposed to the process, inparticular the sensor element, process seal and process fitting, aresuitable for the existing process conditions. These include above allthe process pressure, process temperature as well as the chemicalproperties of the medium.You can find the specifications in chapter "Technical data" or on thetype label.Select an installation position you can easily reach for mounting andconnecting as well as later retrofitting of an indicating and adjustmentmodule. The housing can be rotated by 330° without the use of anytools. You can also install the indicating and adjustment module in fourdifferent positions (each displaced by 90°).Before beginning the welding work, remove the electronics modulefrom the sensor. By doing this, you avoid damage to the electronicsthrough inductive coupling.With threaded versions, the housing must not be used to screw in theinstrument! Applying tightening forces on the housing can damage itsinternal parts.Use the hexagon for screwing in.Use the recommended cables (see chapter "Connecting to powersupply") and tighten the cable gland.You can give your instrument additional protection against moisturepenetration by leading the connection cable downward in front of thecable entry. Rain and condensation water can thus drain off. Thisapplies mainly to outdoor mounting as well as installation in areaswhere high humidity is expected (e.g. through cleaning processes) oron cooled or heated vessels.Suitability for the pro-cess conditionsMounting positionWelding workHandlingMoisture10 VEGAFLEX 61 • Profibus PA4 Mounting31835-EN-100426
