Clean The Circuit Boards Of The Uninterruptible Power Supply With Compressed Air At Least Once A Year.

In the operating environment, equipment inevitably accumulates dust and particles. In the server room or equipment cabinet using industrial ups battery backup, a clean compressed air cleaning of the internal circuit boards and ventilation channels should be performed at an appropriate time.

After disconnecting the power supply to computer ups system, open the chassis. At an appropriate distance, spray electronic-grade compressed air vertically and intermittently to blow away accumulated dust and particles from the board surface, slots, and heat dissipation channels, without using wet cleaning agents or touching the circuitry. After cleaning, check the cooling fans and vents for dust residue to ensure proper ventilation.

This process is recommended at least annually as part of preventative maintenance. Regularly cleaning the large ups battery backup circuit boards and ventilation system can reduce the risk of poor heat dissipation, component moisture damage, or accidental short circuits caused by dust accumulation. Many resources include this type of operation in equipment lifecycle management and maintenance checklists.
