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rating275VAC/0.5Amp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).
For demounting the meter
Pullthearmoftheslidingclampsin
outwarddirection(oppositetometer)and
dragtheslidingclampsawayfromthe
panel.
Dis-assemblethesnapttedbaseclamps
fromthemeterusingascrew-driver
Pushthemeterfrombacksideoutofthe
