•Allpowerwiringandcommunicationcableinstallationmustbe

performedbyauthorizedserviceprovidersworkinginaccordance

withlocal,state,andNationalElectricalCoderegulationsrelated

toelectricalequipmentandwiring,andfollowingtheinstructionsin

thismanual.

•Undersizedwiringmayleadtounacceptablevoltageattheunitand

maycauseunitmalfunctionandbeafirehazard.

•ProperlygroundtheSingleZoneoutdoorandindoorunit.Ground

wiringisrequiredtopreventaccidentalelectricalshockduring

currentleakage.

•Groundwiringmustalwaysbeinstalledbyaqualiedtechnician.

•Donotconnectgroundwiretorefrigerant,gas,orwaterpiping;

tolightningrods;totelephonegroundwiring;ortothebuilding

plumbingsystem.FailuretoproperlyprovideaNationalElectrical

Code-approvedearthgroundcanresultinelectricshock,physical

injuryordeath.

•Installappropriatelysizedbreakers/fuses/overcurrentprotection

switchesandwiringinaccordancewithlocal,state,andNational

ElectricalCoderegulationsrelatedtoelectricalequipmentand

wiring,andfollowingtheinstructionsinthismanual.Usinganover-

sizedbreakerorfusemayresultinelectricshock,physicalinjuryor

death.

•Considerambientconditions(temperature,directsunlight,inclem-

entweather,etc.)whenselecting,installing,andconnectingthe

powerwiring.

•ProperlygroundtheSingleZoneoutdoorandindoorunit.Improp-

erlygroundwirecancausecommunicationproblemsfromelectrical

noise,andmotorcurrentleakage.Groundwiringmustalwaysbe

installedbyaqualiedtechnician.

•Ifthesystemoperatesinreversedphase,itmaydamagethecom-

pressorsandothercomponents.

•Ifthereisapossibilityofreversedphase,phaseloss,momentary

blackout,orthepowergoesonandoffwhilethesystemis

operating,installafield-suppliedphaselossprotectioncircuit.

•Donotconnectgroundwiretorefrigerant,gas,orwaterpiping;

tolightningrods;totelephonegroundwiring;ortothebuilding

General Information and Safety Guidelines

Power Supply / Power Wiring Specifications

•SingleZonesystemsoperateat1Ø,208-230V,60Hz.

•Powersupply,wiretypeandsizeshouldbeselectedbasedonNationalElectricalCodeandlocalcodes.Maximumallowablevoltage

fluctuation±10%ornameplateratedvalue.RefertoFigure54forwiringguidelines.

•ProperlygroundtheSingleZoneoutdoorunitandindoorunitperNationalElectricalCodeandlocalcodes.

•Useonlycopperwiringthatisstrandedandshieldedwiththewiresseparatelyinsulated.

•Groundwireshouldbelongerthanthecommonpower/communicationwires.

•RefertotheinsideoftheChassisCoverforCircuitandTerminalBlockDiagramsforyourmodelunit.

•Alwaysmatchcolorcodesofeachwireandfollowwiringdiagram.
