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.

1.3 Installation procedure
Procedure of installing electrician switch box of centralized controller
The size of the centralized controller wire depends on the length. Use a wiring pipe adaptable
to the wires of the centralized controller to perform installation.

Note
The RS485-to-RS232 module in the wiring diagram and the wires are put into use only when
the network system needs to be connected with the computer. One computer can be connected
with 16 centralized monitors at most. Namely a maximum of 16X64=1024 indoor units can be
connected. The centralized controllers are differentiated by address bits. The configurable range
is 0~15. No duplicate address of centralized controller is allowed in a unified network.
1.5 Safety precautions
Safety precautions
! Read the safety precautions carefully before installing the unit.
! Stated below are important safety issues that must be obeyed.
! The meanings of all parts are as follows:
Warning
Means improper handling may lead to personal injury or property loss.
Note
Means improper handling may lead to personal injuries.
! Upon completion of the installation, check whether the trial run is normal, and deliver the
user's manual to the user.
Warning
Please entrust the distributor or professionals to install the equipment. Installation by unauthorized
persons may lead to imperfect installation which may result in electric shock or fire.
Adhere to this installation manual. Improper installation may lead to electric shock or fire.
Reinstallation must be performed by professionals. Improper installation may lead to electric
shock or fire.
Do not uninstall the equipment without permission. Unauthorized uninstalling may lead to abnormal
operation, heating or fire of the air conditioner.
Note
Do not install the equipment in a place vulnerable to leakage of flammable gases. Once
flammable gases are leaked and left around the centralized monitor, fire may occur.
The wiring shall adapt to the current of the centralized monitor. Otherwise, electric leakage or
heating may occur and result in fire.
