With high process temperatures exceeding 80 °C,you have to use amounting adapter for the emitting and receiving unit.The mountingadapter can be only used with the encapsulated horn antenna withPTFE cover.Fig.3:VEGAMIP 61 with high temperature mounting adapterMounting adapterVEGAMIP U61 • - Relay 113Product description-EN-100531
4Mounting4.1General 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.Make sure that all parts of the instrument exposed to the process,inparticular the antenna,seal and process fitting,are suitable for theexisting process conditions.These include above all the processpressure,process temperature as well as the chemical properties ofthe medium.You can find the specifications in chapter "Technical data"or on thetype label.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.4.2Mounting instructionsIf possible,install VEGAMIP 61 in a position where a high signaldamping by the medium is expected.Screwing inSuitability for the pro-cess conditionsMoistureSwitching point12 VEGAMIP U61 • - Relay4Mounting-EN-100531
Avoid mounting the instrument too close to the vessel wall.Reflectionsfrom the vessel wall or from vessel installation can influence theswitching accuracy.Fig.4:Installation position (top view)IfVEGAMIP 61 is mounted in the filling stream,unwanted falsemeasurement signals can be generated.For this reason,mountVEGAMIP 61 at a position in the vessel where no disturbances,e.g.from filling openings,agitators,etc., can occur.Microwaves can penetrate non-conductive materials.Hence,it ispossible to measure through the wall of non-conductive vessels.Fig.5:Bulk solids vessel of plasticIn metal vessels,you have to mount VEGAMIP 61 on flanges orthreaded sockets.It is also possible to measure through a window.Ingeneral,all products such as glass,ceramic and plastic are suitable aswindow material.Inflowing mediumNon-metallic vesselsMetal vesselsVEGAMIP U61 • - Relay 134Mounting-EN-100531

In tight mounting spaces or spaces subject to high temperatures,thesignal of VEGAMIP 61 can be guided via a deflector.You can use ametal plate for this or an angled antenna extension on the side of theemitting unit.In products with low dielectric value,we recommendusing an instrument version with antenna extension because itfocusses the signal optimally and has no signal loss.With instrumentversions with detachable horn antenna,the antenna extension can beretrofitted.45°1 2Fig.12:Possibilities for signal deflection1Metal plate for signal deflection of the microwave signal2Bent antenna extensionSpecial mounting op-tions18 VEGAMIP U61 • - Relay4Mounting-EN-100531
5Connecting to power supply5.1Preparing the connectionAlways keep in mind the following safety instructions:lConnect only in the complete absence of line voltagelIf overvoltages are expected,install overvoltage arrestersConnect the operating voltage according to the following diagrams.The oscillator with relay output is designed in protection class 1.Tomaintain this protection class,it is absolutely necessary that theground conductor be connected to the internal ground terminal.Takenote of the general installation regulations.As a rule,connectVEGAMIP 61 to vessel ground (PA), or in case of plastic vessels,tothe next ground potential.On the side of the housing there is a groundterminal between the cable entries.This connection serves to drain offelectrostatic charges.InEx applications,the installation regulations forhazardous areas must be given priority.The data for power supply are specified in chapter "Technical data".The instrument is connected with standard two-wire cable withoutscreen.If electromagnetic interference is expected which is above thetest values of EN 61326 for industrial areas,screened cable should beused.Use cable with round cross-section.Acable outer diameter of 5…9mm(0.2…0.35 in)ensures the seal effect of the cable gland.If you areusing cable with a different diameter or cross-section,exchange theseal or use a suitable cable gland.5.2Connection procedureThe connection of the voltage supply and the signal output is carriedout via the spring-loaded terminals in the housing.Proceed as follows:1Unscrew the housing cover2Loosen compression nut of the cable entry3Remove approx.10 cm (4in)of the cable mantle,strip approx.1cm (0.4in)of insulation from the ends of the individual wiresSafety instructionsVoltage supplyConnection cableConnection technologyConnection procedureVEGAMIP U61 • - Relay 195Connecting to power supply-EN-100531
