102 Remark ：1.The wire diameter and continuous length in the table are applicable to a maximum distance of 20 meters. If the power wiring exceeds

20 meters and the voltage drop exceeds the range of 2%, please choose a wire diameter with a larger cross-sectional area.

2.The selection of the power cord is based on the ambient temperature of 40°C.

3.The wire current carrying capacity in the attached table is only for the user's reference. The actual interception capacity of the wire

varies depending on the type and length of the cable, the way of pipe penetration, and the actual laying environment, and the correction

factor is different.

Electrical system and installation

Please design the dedicated power supply for IDU and ODU separately.

In order to reduce interference, it is recommended to use two-core shielded cables for the signal cables of the IDU and

ODU. Please do not use multi-core cables without shielding.

The power supply should be equipped with a leakage protector and a manual switch.

During installation, the communication line and the power line must not be intertwined, and must be routed separately,

and the minimum distance should be greater than 20CM, otherwise the communication of the unit may be abnormal.

Power wiring must be entrusted to professional electricians.

The power supply, leakage protector and manual switch of the IDU connected to the same ODU are required to be

universal. (Please use the same circuit for the IDU power supply of the same system. And it must be turned on and off at

the same time, otherwise it will seriously affect the service life of the system, and unpredictable situations may occur. )

Please integrate the IDU and ODU connection wiring system and refrigerant piping system into the same system.

Installation options

103

Signal lines must be shielded. Using other wires may cause signal interference and cause malfunction.

The shielding nets of all shielded wires are connected to each other and finally connected to the sheet metal ground at

one point.

It is forbidden to bundle signal wires, refrigerant pipes, power wires, etc. together. When the power line and the signal

line are laid in parallel, they should be kept at a distance of more than 300mm to prevent the signal source from

being disturbed.

Please use two-core shielded wire ( ≥ 0.75mm²) for the signal cable of indoor and outdoor units, without polarity.

The signal cable of indoor and outdoor units should be connected as far as possible from the end of the outdoor unit.

Signal lines cannot form a closed loop.

The signal line has no polarity, and there is no need to distinguish it when wiring.v

Remarks: The wiring diameter and continuous length in the table indicate that the voltage drop is within 2%. When the continuous wiring

length exceeds the value in the table, please follow the relevant regulations to select the wire diameter.

Remarks:

1. Please use the refrigerant piping system, the indoor unit-indoor unit room, and the indoor unit-outdoor unit connection signal line as the

same system.

2. All the internal units in the same system must be powered in a unified manner, and some internal units cannot be cut off, otherwise the

unit will fail.

3. When the power cable and the signal cable are parallel, please put the wires into their respective wire ducts, and leave a suitable distance

between the wires. (Distance between power cables: 300mm below 10A, 500mm below 50A)

4. When multiple outdoor units are connected in parallel, the main outdoor unit must be set. (Refer to the settings of the DIP switch)
