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

panelwindowandremovethegasketfrom
