1.3 Installation methods
1.2Installation instructions
1) Connect220VACpower tothe L Nterminalsofthe centralized controller directly.
2) Do notlay the signalwireand thepowerwire ofthe centralized controller inthe samepower
wire pipe,there shouldbe300~500mm distancebetween two pipes.
3) The signalwire ofcentralized controllershouldnotexceed 1200m.
4) No intermediatejointis allowed for the shielded cable.Ifjointsare inevitable,crimpitwiththe
terminalblock.
5) After the centralized controllerisconnected,do notusemegohmmeter toinspectthe insulation
ofthe signalcable.
6) Wiring mode ofthe centralized controller and the network interface:
The communicationport betweenthe centralized controller and the network interfaceofthe air
conditioner is polarity-sensitive.The X,Yand Eatbothsidesshouldcorrespond properly.Dot
notcross-connectthe signalwires,the sametothe RS485-RS232 ofthe centralized controller.

can connect.The centralized controllerscan be distinguished byaddress code,whichsetting range
is0to15.No duplicateaddressesisallowed inasamenetwork.
