4.4 Wired Controller Installation 

Wired controller is optional accessory. If wired controller is needed, please contact your 

local dealer and install the wired controller according to the instruction manual. 

Note: 

Do perform the commissioning operation before first use, automatic addressing or other 

settings, please refer to the manual of ODU. 

5 Wiring Work 

Notes: 

 Units must be grounded securely, or it may cause electric shock. 

 Please carefully read the wiring diagram before carry out the wiring work, incorrect 

wiring could cause malfunction or even damage the unit. 

 The capacity of power supply must be sufficient and the sectional area of wires in the 

room should be above 2.5 mm

2

 The unit should be powered by independent circuit and specific socket. 

 The wiring should be in accordance with related regulations in order to ensure the units 

reliable running. 

 Install circuit breaker for branch circuit according to related regulations and electrical 

standards. 

 Crimp terminal or single wire must be applied for all wires. 

 Keep cable away from refrigerant piping, compressor and fan motor. 

 Do not change the wiring inside the unit. 

 If there is strong electromagnetic interference around the unit, shielded twisted pair line 

should be applied; the metal shielded layer of twisted pair wire must be grounded to 
avoid electromagnetic interference. 

 The communication wires should be separated from power cord and connection wire 

between indoor unit and outdoor unit. 

5.1 Connection of Wire and Patch Board Terminal 

(1)  The connection of wire (as shown in Fig.5.1.1) 

1) Strip about 25mm insulation of the wire end by stripping and cutting tool. 
2) Remove the wiring screws on the patch board. 
3) Shape the tail of wire into ring by needle nose plier, and keep the gauge of ring in 

accordance with screw. 

4) Use the screwdriver for tightening the terminal. 

(2)  The connection of stranded wire (as shown in Fig.5.1.2) 

1) Strip about 10mm insulation of the end of stranded wire by stripping and cutting tool. 
2) Loosen the wiring screws on patch board. 
3) Insert the wire into the ring tongue terminal and tighten by crimping tool.
