What should be paid attention to in the wiring of the inverter air conditioner, and if the wrong wir

Precautions for inverter air conditioner wiring:

1) The purpose of grounding:

1. In the power system, the grounding required for operation, such as neutral grounding, is called working grounding.

2. The metal shell of electrical equipment, reinforced concrete poles and metal towers, etc., may be charged due to insulation damage, and the grounding set up to prevent this voltage from endangering personal safety is called protective grounding. Protective grounding is the most used security measure for electrical equipment and electrical lines in low-voltage distribution systems and high-voltage power systems where the neutral point is not grounded.

3. Grounding voltage protection devices, such as lightning rods, lightning arresters and clearance guards, etc., are grounded in order to eliminate the danger of overvoltage, which is called overvoltage protection grounding.

2) The function of grounding: to prevent electromagnetic coupling interference: such as grounding of digital equipment; RF cable wiring, shielding, grounding, etc.; Prevent strong electricity and lightning strikes communication equipment: such as the grounding of the rack and the casing of general communication equipment, to prevent equipment, instruments, and personal injury.

When the inverter air conditioner is used for the indoor unit, it is necessary to pay attention to the zero line, live wire, and communication line when wiring the outdoor unit, so as not to connect the wrong line, otherwise it will not work normally. But it doesn't burn out the air conditioner.

In the installation is the same as the ordinary air conditioning steps, if it is a single-phase air conditioner, you only need to insert the plug into the socket, there is no problem of connecting the wrong wire, if it is a three-phase air conditioner, you follow the yellow, green and red logo at the power supply, respectively, connect the yellow, green and red, and black to protect the zero line.

Will burn the board, I've encountered it many times.

No. If the power cord and signal control cable are connected incorrectly, the outdoor unit cannot receive the signal sent by the indoor unit control motherboard, and the circuit of the compressor cannot form a circuit, let alone burn out.

If the three-phase air conditioner is misconnected due to the mismatch of the phase sequence, in order to protect the compressor, only a variety of protection circuits are designed on the circuit, so that the air conditioner has protection functions such as overvoltage, undervoltage, overcurrent, overheating and pressure protection.

Some compressors of air conditioners are equipped with thermal relays inside, which can be used for over-current protection and over-temperature protection, and enter the protection when one of the conditions is met; Three-phase air conditioners also have phase sequence and phase loss protection functions. So there will be no damage.

Before wiring the air conditioner, be sure to clarify the zero line and live wire, and connect the zero line to the n terminal.

I walked with others on the air conditioning internal electrical line. As a result, others said that the motherboard was burned. Say it's my responsibility.

As long as it is not connected to the neutral wire and the live wire, it will not burn out, at most it will not be opened, and now the air conditioning wiring is more foolish, and it will not be wrong to connect it according to the color.

Kiss! Hello, happy to answer your <>

If the power cord and signal control line are connected to the wrong line, the outdoor unit cannot receive the signal sent by the control board of the indoor unit, and the circuit of the compressor cannot form a loop, let alone burn out. If the three-phase air conditioner is wrong due to the mismatch of the phase sequence, in order to protect the compressor, only a variety of protection circuits are designed on the circuit, so that the air conditioner has protection functions such as overvoltage, undervoltage, overcurrent, overheating and pressure protection. Some compressors of air conditioners are equipped with thermal relays inside, which can be used for over-current protection and over-temperature protection, and enter the protection when one of the conditions is met; The three-phase air conditioner also has the functions of phase sequence and phase loss blind call.

So there will be no damage. Hope mine can help you <>

Summary. Hello dear, glad to answer for you, <>

The consequence of the transformer connecting to the wrong line of the air conditioner is: it leads to abnormal cooling or heating of the air conditioner. After the transformer is connected to the wrong wire, it will generally lead to abnormal refrigeration or heating of the air conditioner, resulting in the failure of the air conditioner to start, making the air conditioner shell electrified, resulting in accidental electric shock accidents.

In order to effectively ensure that the air conditioner can operate normally and there will be no potential safety hazards, when we wiring the air conditioner, we must wire it according to the correct installation requirements, and it must not be reversed.

The transformer in the alley is connected to the wrong line, and the neighbor's home appliance oil Qifan smoke machine is burned, so it happens that my family's air conditioner, TV series, and washing machine are all plugged into the plug board, will it also burn filial piety?

Hello Air conditioners, TV dramas, and washing machines are all plugged into the plug board and may not burn out. For example, if the TV is only turned off the remote control, but there is still a part of the circuit in the TV working, this situation will burn. If you turn off the TV switch directly, the TV will not burn.

Regardless of whether it is turned on or not, as long as it is burned, you can talk to an electrician and the power supply bureau for compensation. If you connect the wrong wire, you can make trouble and see it.

There will be no big problem if the air conditioner is connected to the wrong line, because after the air conditioner is connected to the wrong line, it will be detected by the main control computer, and the air conditioner will report a fault and not work at this time. If the rough digging is the wrong connection on the circuit, it may directly lead to the failure to turn on, and it needs to be connected correctly before it can be used.

Extended Information: How to use the remote control of the air conditioner:

The remote control of the air conditioner is kept facing the indoor unit of the air conditioner. Select the mode, keep pressing the "mode" button, and the four modes of "cooling, heating, dehumidification, and air supply" will be cycled. Press the "Switch" button to turn the air conditioner on or off.

Press the up and down buttons of the temperature adjustment to adjust the temperature you need. Adjust the wind speed, generally there are four gears: large, medium, small and automatic. Adjust the direction of the air supply outlet, press the "wind direction" key rock core, generally press once is an angle, cycle back to the first angle after 5 to 6 times, or you can choose automatic swing air supply.

Timing power on/off, repeat the button to set the time, you can set the time interval of timing to start or off, let go and do not press the time interval to take effect, set to 0 is not to use the timing function.
