4 Mounting4.1 General instructionsWith instruments with threaded process fitting, suitable tools must beapplied for tightening the hexagon.Warning:The housing must not be used to screw the instrument in! Applyingtightening force can damage internal parts of the housing.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.Make sure that all parts of the instrument exposed to the process, inparticular the active measuring component, process seal and processfitting, are suitable for the existing process conditions. These includeabove all the process pressure, process temperature as well as thechemical properties of the medium.You can find the specifications in chapter "Technical data" and on thetype label.4.2 Instructions for installationBy using the standpipe version, the influence of turbulence and vesselinstallations, such as e.g. heating spirals or agitators, is excluded. Ifturbulence or vigorous product movement occurs in the vessel, longstandpipe antennas should be fastened to the vessel wall.The standpipe antenna must extend all the way down to the requestedmin. level, as measurement is only possible within the tube. If a goodmixing of the product is important, you should use a version withperforated surge pipe.Warning:Remember that with the version with ¾" thread, a max. torque of80 Nm (59 lbf ft) must not be exceeded.Screwing inMoistureSuitability for the pro-cess conditionsInstallation12 VEGAPULS 62 standpipe version • Foundation Fieldbus4 Mounting36510-EN-120301
