7.3 PositionofElectricalWiringConnection
● Tightly secure wirings to the terminal
block according to the specied torque. If
tightening the terminals is not completed,
heat generation, an electric shock or a re
will occur at the terminal connection.
● Make sure that the wires are securely xed
in order not to apply an external force to the
terminal connection of the wirings. If xing is
not completed, heat generation or a re will
occur.
• Theelectricalwiringconnectionfortheindoor
unitisshownintheitem7.2.2.
• Theconnectionattheterminalblockforthe
indoorunitisshowninthegurebelow.Check
theoutdoorunitforthecombinationbeforethe
wiringwork.Thescrewsattheterminalblock
shouldbeperformedaccordingtothetightening
torqueasshowninthetablebelow.
(1) Connectthecablefortheoptionalwired
controllerortheoptionalextensioncable
totheterminalsinsidetheelectricalbox
throughtheconnectingholeinthecabinet.
(2) Connectthepowersupplyandtheearth
wirestotheterminalsintheelectricalbox.
(3) Connectthewiresbetweentheindoorunit
andtheoutdoorunittotheterminalsinthe
electricalbox.
(4) Connectcablescorrectlytomatchthe
terminalNo.andthemarkband.
(5) Connectthetransitionwiresbetweenindoor
unitsconnectedtothesameoutdoorunit.
(6) Donotconnectthemainpowersource
cablestothecontrolline(TerminalsA,B,
1and2ofTB2).Ifconnected,theprinted
circuitboard(PCB)willbebroken.
(7) Tightlyclampthewiresusingthecordclamp
insidetheelectricalbox.
(8) Standardcompliancewheninstallingtheunit
inAustralia.
(a) Connectthebothendsofshieldedtwist
paircable(controllercableandcontrol
cable)totheearthasshownbellow.
