How to correctly replace the UPS battery?

The correct way to replace the UPS battery: 1. First, make preparations to ensure the input power supply of the UPS host, the registration inspection of the new and old batteries, the sealing of the smoke probe of the fire fighting system in the computer room, and the preparation of the carbon dioxide fire extinguisher. Before replacing the battery, make relevant registration records for the UPS host, old battery packs, battery monitors and other equipment, especially the placement of each layer of batteries and the wiring of the battery monitors. Mark and draw the connection diagram. Ensure that the effect after the battery pack is replaced is consistent with the original situation. 2. Second, familiarize yourself with the UPS host battery installed on site before replacing it, disconnect the connection switch between the UPS host and the battery pack, disconnect the UPS host and the battery pack, and ensure the safety of the staff when replacing the battery. Disassemble the batteries of the original battery pack. The battery replacement executive engineer is responsible for the disassembly of the battery, and the relevant auxiliary technicians carry out the handling of the old and new batteries. 3. After the UPS battery pack is replaced correctly, professional staff use a multimeter to check the total voltage of the battery pack, the positive and negative poles of the battery pack, and the connection of the neutral wire. After ensuring that the battery pack and the UPS host are normal, close the battery pack switch to restore the UPS uninterruptible power supply system to normal operation. Then check the UPS's working voltage, current, charging voltage, working status, etc. and make a record. One person observes whether the parameters in the LCD display of the main unit are consistent with the actual ones, and the battery time parameters are adjusted and set to ensure that the battery will not give false alarms during the normal life of the battery. 4. Confirm that the generator is running stably. After the voltage measured at the input of the transfer switch in the power distribution cabinet is normal, switch the switch to the generator side, observe and confirm that the UPS host is operating normally, and disconnect the battery circuit breaker in the battery cabinet. 5. Remove the old battery. Remove the battery from the top to the next section of the UPS battery rack. After removing a screw, wrap the connector of the cable with electrical tape to insulate it to prevent the positive and negative poles from being short-circuited and dangerous. . 6. Remove all the batteries, place them, and start installing new batteries. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
