Installation Guidelines
1. Thisequipment,beingbuilt-in-type,normallybecomesapartofmaincontrolpanelandinsuchcasetheterminals
donotremainaccessibletotheenduserafterinstallationandinternalwiring.
2. Conductorsmustnotcomeincontactwiththeinternalcircuitryoftheequipmentorelseitmayleadtoasafety
hazardthatmayinturnendangerlifeorcauseelectricalshocktotheoperator.
3. Circuitbreakerormainsswitchmustbeinstalledbetweenpowersourceandsupplyterminalstofacilitate
power‘ON’or‘OFF’function.Howeverthisswitchorbreakermustbeinstalledinaconvenientpositionnormally
accessible to the operator.
4. Beforedisconnectingthesecondaryoftheexternalcurrenttransformerfromtheequipment,makesurethatthe
currenttransformerisshortcircuitedtoavoidriskofelectricalshockandinjury.
5. Theequipmentshallnotbeinstalledinenvironmentalconditionsotherthanthosementionedinthismanual.
6. Theequipmentdoesnothaveabuilt-in-typefuse.Installationofexternalfuseof0.5A,ClassgGtypeforelectrical
circuitryishighlyrecommended.
7. Removethescratch-guardfromthemeterdisplayduringcommissioningofthepanel.
Wiring Guidelines
1. Topreventtheriskofelectricshock,powersupplytotheequipmentmustbekeptOFFwhiledoingthewiring
arrangement.
2. Wiringshallbedonestrictlyaccordingtotheterminallayout.Conrmthatallconnectionsarecorrect.
3. Useluggedterminals.
4. Toreduceelectromagneticinterferenceuseofwireswithadequateratingsandtwistsofthesameinequalsize
shallbemadewithshortestconnections.
5. LayoutofconnectingcablesshallbeawayfromanyinternalEMIsource.
6. Cableusedforconnectiontopowersource,musthaveacross-sectionof1mm2to2.5mm2.Thesewiresshallhave
currentcarryingcapacityof6A.
7. Coppercableshouldbeused(StrandedorSinglecorecable).

Thereare4dedicatedkeyslabelledasF1,F2,F3,F4.Usethese4soft-touchkeysto
read meter parameters.
Thekeyshavemultipleassignments.Functionassignmentsandkeylabellingchange
accordingtothecontextofoperatorinput.
Ashorttouchonthekeytriggersthefunctiononce.Holdingthekeyforlonger
switchesontheautorepeatfunctionafterapproximately1s.
Thefunctionofthekeyistriggeredrepeatedlywhilethekeyistouchedcontinuously.
Autorepeatisuseful,forexample,forfastincrementingofvalueswhen
parameterizingthedevice.
