7.1 Power Cord Connection

7.3 Communication Wiring

 

All the supplied parts, materials and electrical works must comply with 

local regulations.

 

Use only copper wires.

 

Use a dedicated power supply for the air-conditioners. The power 

voltage must be in line with the rated voltage.

 

The electrical wiring works must be carried out by a professional 

technician, and must comply with the labels stated in the circuit diagram.

 

Before the electrical connection works are carried out, turn off the 

power supply to prevent injuries caused by electric shock.

 

The external power supply circuit of the air conditioner must include 

an earth line, and the earth line of the power cord connecting to the 
indoor unit must be securely connected to the earth line of the 
external power supply.

 

Leakage protective devices must be configured according to the local 

technical standards and requirements for electrical and electronic devices.

 

The fixed wiring connected must be equipped with an all-pole 

disconnection device with a minimum 3 mm contact separation.

 

The distance between the power cord and signalling line must be at 

least 300 mm to prevent the occurrences of electrical interference, 
malfunction or damage to electrical components. At the same time, 
these line must not come in contact with the piping and valves.

 

Choose electrical wiring that conforms to the corresponding electrical 

requirements.

 

Connect to the power supply only after all the wiring and connection 

works have been completed, and carefully checked to be correct.

Figure 7.2 shows the power supply terminal of the indoor unit.

Refer to Tables 7.1 and 7.2 for the specifications of the power cord and 
communication wire. A wiring capacity that is too small will cause the 
electrical wiring to become too hot, and lead to accidents when the unit 
burns and becomes damaged.

Š

 

Use only shielded wires for the communication wiring. Any other type of wires 

may produce a signal interference that will cause the units to malfunction.

Š

 

Do not carry out electrical works like welding with the power on.

Š

 

All shielded wiring in the network are interconnected, and will 

eventually connect to earth at the same point “     ” .

Š

 

Do not bind the refrigerant piping, power cords and communication 

wiring together. When the power cord and communication wiring are 
parallel, the distance between the two lines must be 300 mm or more 
in order to prevent signal source interference.

Š

 

Communication wiring must not form a closed loop.

Refer to local laws and regulations when deciding on the dimensions for the 
power cords and wiring. Get a professional to select and install the wiring.

Proper power wiring connections

When connecting to the power supply terminal, use the circular wiring terminal 

with the insulation casing (see Figure 7.3).

Use power cord that conforms to the specifications and connect the power cord 

firmly. To prevent the cord from being pulled out by external force, make sure it 

is fixed securely.

If circular wiring terminal with the insulation casing cannot be used, please 

make sure that:

Use the same power supply, circuit breaker and leakage protective 

device for the indoor units connected to the same outdoor unit.
