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" and 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°).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.Fig. 3: Measures against moisture penetration4.2 Mounting stepsFor mounting VEGABAR 54, a welded socket is required.
