1.2 Notes to installation
Notes to installation
1) Directly insert 220V~50Hz power into the wiring socket L, N terminals of centralized
controller.
2) Do not lay the signal wire and the power wire of the centralized controller in the same power
wire pipe, there should be 300~500mm distance between two pipes.
3) The signal bus of centralized controller should not exceed 1200m.
4) No intermediate joint is allowed for the shielded cable. If joints are inevitable, crimp it with the
terminal.
5) After the centralized controller is connected, do not use megohmmeter to inspect insulation of
the signal cable.
6) Wiring mode of the centralized controller and the network interface:
The communication port between the centralized controller and the network interface of the air
conditioner is polarity-sensitive. The X,Y and E at both sides should correspond properly. Dot
not cross-connect cables. The same principles apply to the RS485-RS232 of the centralized
controller.
