The main reasons why the split meter ready board needs dust-proof measures are as follows:

Protect the normal operation of the equipment: Dustproofing can prevent dust, debris, etc. from entering the inside of the split meter ready board and preventing them from accumulating on the surface of the meter and other equipment, affecting the normal operation of the equipment and the accuracy of readings.

Extend the life of the equipment: The electronic components and mechanical parts in the split meter ready board are sensitive to dust and debris. Dust-proof measures can help reduce the corrosion and wear of the equipment by these particles, thereby extending the service life of the meter and related equipment.

Reduce maintenance costs: Dust prevention can reduce the frequency of cleaning and maintenance inside the equipment, reducing maintenance costs and manpower investment.

Improve safety: Dust-proof measures help prevent short circuits and other faults inside the split meter ready board, improve the safety of equipment operation, and reduce risks such as fires.

Therefore, in order to ensure the normal operation of the meter, extend its life, reduce maintenance costs and improve safety, the split meter ready board usually needs to take effective dust-proof measures.
