4. Utilize communication functions
Most large and medium-sized UPS systems have operational capabilities such as communication with microcomputers and program control. Install the corresponding software on the microcomputer, connect the UPS through the serial/parallel port, run the program, and use the microcomputer to communicate with the UPS. Generally, it has functions such as information inquiry, parameter setting, timing setting, automatic shutdown, and alarm. Through information retrieval, information such as the input voltage of the mains, the output voltage of the UPS, the load utilization rate, the battery capacity utilization rate, the temperature inside the machine, and the mains frequency can be obtained; Through parameter settings, basic characteristics of UPS, battery maintenance time, and battery depletion alarm can be set. Through these intelligent operations, the use and management of UPS power supplies and their batteries have been greatly facilitated.
5. Maintenance and upkeep during use
Before use, carefully study the instruction manual and user manual. Strictly follow the correct startup and shutdown operating procedures. It is strictly prohibited to frequently turn on and off the UPS power supply, and overloading is also prohibited. When the battery is used to protect the shutdown, it must be recharged before use and cannot be directly turned on.
6. Timely replace waste/damaged batteries
The number of batteries equipped with large and medium-sized UPS power supplies ranges from 3 to 80, or even more. These individual batteries form a battery pack through circuit connections to meet the needs of UPS DC power supply. In the continuous operation and use of UPS, it is inevitable for individual batteries to experience performance degradation and storage capacity failure due to differences in performance and quality, resulting in damage.
When one or more batteries in the battery pack are damaged, maintenance personnel should inspect and test each battery to eliminate the damaged ones. When replacing a new battery, one should strive to purchase batteries from the same manufacturer and model. It is prohibited to mix acid resistant batteries, sealed batteries, or batteries of different specifications.
