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
