4.5 Installation of Wired Controller 

Please refer to User Manual of Wired Controller for the installation details. 

 

When installation is finished, the unit must be tested and debugged before operation. Please refer to Instruction 
Manual of ODU for auto addressing and debugging details. 

5 Wire Connection 

Before obtaining access to terminals, all supply circuits must be disconnected. 

 

(1)  For personal safety, the air conditioner must be properly grounded. 

(2)  Read carefully the voltage indicated on the nameplate before connecting wires. Then connect wires according to 

the wiring diagram. Improper wiring will lead to abnormal operation or damage the unit. 

(3)  Power capacity should be large enough. Sectional area of room wires should be above 2.5mm

2

(AWG13). 

(4)  For unit's power supply, please use specialized branch circuit and specialized power socket. 

(5)  All wiring must comply with standards to ensure safe and correct operation. 

(6)  Install specialized branch circuit breaker according to related laws and regulations and electrical standards. 

(7)  All wiring must use pressure terminal or single wire. Multi-twisted wire that connects directly to the wiring board 

may cause fire hazard. 

(8)  Keep the wires away from refrigerant pipe, compressor and fan. 

(9)  Do not alter the inner wires of air conditioner. Manufacturer does not assume responsibility for damage or 

abnormal operation due to this reason. 

(10) If the unit is installed in places with strong electromagnetic interference, it's recommended to use twin-twisted 

shield wire. During wire connection, please pay attention that the metal shield layer of the twin-twisted wire must 
be grounded(outer case) in order to prevent the unit from electromagnetic interference. 

(11) Communication line should be separated from the power cord and the connecting wire of IDU and ODU. 

(12) If the project needs higher static pressure, you can set it through the wired controller. 

5.1 Connection of Wire and Wiring Board Terminal 

(1)  Connection of Single Branch Line (shown in Fig 5.1.1). 

1)  Use a wired stripper to strip away about 25mm (1 in.) of the insulation layer at the end of 

single branch line so that the single-core wire can be exposed. 

2)  Use a screwdriver to remove the terminal screw on the terminal board. 

3)  Use a plier to bend the end of single branch line until it forms a circle that has a similar 

size with the screw. 

4)  Lead the screw across the circle of the single branch line and fix it on the wiring board.
