What should I do when encountering accidents with UPS power supply during use? How to prevent UPS from malfunctioning. In the process of using UPS uninterruptible power supply, we often encounter some faults that cause UPS to not be able to start up or be damaged and cannot be used normally. In order to help everyone quickly solve these faults, the following editor will introduce the methods and prevention of UPS power supply accidents, hoping to bring some help to everyone.

1、 What should I do when encountering accidents with UPS power supply during use?
1. If the UPS uninterruptible power supply equipment fails due to a public power grid accident, the upper power supply should be isolated before dealing with the lower power supply.
2. Calm down and prevent accidents from escalating, but in the process of handling UPS uninterruptible power supply equipment, it is necessary to handle faults based on a modular structure, block by block, to prevent unaffected modules or areas from being affected or implicated, and to prevent the scope of accident handling from expanding.
3. The newly installed UPS uninterruptible power supply device may not start properly, possibly due to the user not connecting the UPS to the power supply. You can first check whether the battery connection plug on the panel behind the UPS power supply is connected; If not, open the front panel again to check if the battery is connected.
4. When encountering faults in the high-voltage power grid or lightning strikes, personnel safety should be evaluated, and it is prohibited to send personnel into the computer room during faults in the high-voltage power grid or when there is still a risk of lightning strikes. When encountering power supply failures in UPS systems caused by uncontrollable forces such as flash floods and earthquakes, the safety of maintenance personnel should be ensured first before emergency handling can be carried out.
5. The UPS power supply has been used for about two years or more, and the power supply cannot start. This may be due to the battery's capacity generally decreasing or the battery becoming inert after two years of use. If the battery cannot function as a delay, users should consider replacing it with a new battery to prevent the battery from becoming inert. We can use battery automation management software.

2、 How to prevent UPS from malfunctioning?
(1) When using UPS, outputting strong current can easily cause poor heat dissipation. It is important to pay attention to good ventilation to facilitate heat dissipation and maintain a clean environment;(2) If during the power supply process of the generator, it should be ensured that the generator power is greater than twice the rated power of the UPS, and the UPS can only be connected after the generator starts stably;
(3) In any case, battery short circuit or deep discharge should be prevented, as the cycle life of the battery is related to the discharge depth, and the deeper the discharge depth, the shorter the cycle life. In capacity testing or discharge maintenance, discharge up to 30% to 50% of the capacity is sufficient;
(4) After the UPS uninterruptible power supply equipment reaches the standby time, the load will still be powered off, but it will not cause economic losses. Another requirement for UPS in data centers and industrial settings is true uninterrupted power supply, which must be available 24 hours a day throughout the year;(5) Under normal use, the maintenance of UPS uninterruptible power supply equipment should pay more attention to dust prevention and regular dust removal. Especially in areas with dry climates, there are a lot of ash particles in the air, and the wind inside the machine can bring dust into the machine for deposition. When encountering humid air, it can cause the control of the main engine to be disrupted, resulting in inaccurate alarms and poor heat dissipation of the components due to a large amount of dust. Generally, it should be thoroughly cleaned once every quarter. Secondly, during dust removal, check for any loose or loose connections and connectors.
