Besides the battery, what other components of the UPS need to be maintained?
The uninterruptible power supply (UPS) system is the core guarantee to ensure the continuous operation of critical equipment in case of power interruption or instability. Although the battery is one of the most important components of the UPS, the reliability and performance of the entire UPS system depends on several other components. In order to maintain the efficient operation of the UPS, users should regularly maintain and check these components. This document describes the main components of the UPS system except batteries and their maintenance points.
main content
Control panel
Check whether all indicators and parameters on the control panel are normal and confirm that there is no alarm information.
Check whether the input switch of the UPS works properly.
Battery circuit breaker (optional) for internal batteries
Check whether the battery circuit breaker works properly and ensure that it cuts off and connects the power supply correctly.
Power module (UPM)
Each UPM contains a rectifier, battery converter, inverter converter, and independent control device. You need to check whether these components work properly.
Check whether the maintenance bypass switch works properly to ensure that maintenance can be performed safely when required.
Fan and ventilation system
Clean the ventilation ducts and grilles of the UPS system regularly to ensure good air circulation. Replace the UPS fan every 20,000 hours.
Filter capacitors and lithium batteries for data memory storage on the control board
It is recommended to replace these components every 50,000 hours to maintain the normal operation of the UPS.
Cable and distribution
Check the reliability of the connection parts such as the feed bus, cable and soft connection, and measure the pressure drop and temperature rise.
Electrical protection system
Including fuses, circuit breakers and other devices, used to protect electrical equipment from short circuit and overload, it is necessary to check its operating status regularly.
Transformer
Used to boost or buck power to ensure the normal power supply of the device. It is necessary to check the status of the device regularly.
Appearance and wiring
Check whether the hardware configuration, marking and wiring of the device meet the requirements of the drawing, and whether there is loosening and corrosion.
Switching switches and modules, buttons, keyboards
Check whether these parts operate flexibly and feel good.
CONCLUSION
The reliability of a UPS system depends not only on the battery, but also on the health of multiple components. Periodically check and maintain components such as transformers, rectifiers, inverters, bypass switches, cooling fans, monitoring software, input/output ports, and network ports to ensure the stable running of the UPS system. By establishing a robust maintenance process, users can significantly improve the reliability of the UPS and reduce the risk of failure, thereby providing lasting power protection for critical equipment.
