12V27A battery.What is the process for replacing a large-capacity battery in an uninterruptible power supply UPS?

The process of replacing a large-capacity battery with an uninterruptible power supply (UPS): 1. The construction workers bring the installation and testing tools to the computer room construction site. 2. Check to confirm that the sleeve handle and wrench handle are well insulated. 3. Plug the generator output line into the backup power industrial connector, start the generator, and let the generator run first. 4. Open

The process of replacing large-capacity battery with uninterruptible power supply UPS

1. The construction personnel bring the installation and testing tools and arrive at the computer room construction site.

2. Check to confirm that the sleeve handle and wrench handle are well insulated.

3. Plug the generator output line into the backup power industrial connector, start the generator, and let the generator run first.

4. Open the battery cabinet and take photos for backup. Find the output cable connected to the UPS host and confirm the positive and negative poles.

5. Confirm that the generator is running stably. After measuring the normal voltage at the input end of the transfer switch in the distribution cabinet, switch the switch to the generator side, observe and confirm that the UPS host is running normally, and disconnect the battery circuit breaker in the battery cabinet.

6. Remove the old battery. Remove the battery from top to bottom on the battery rack. Remove one screw and wrap the connecting wire connector with electrical tape to insulate it well (this step is very important, don’t be lazy) to prevent it from being damaged. The negative pole is short-circuited and dangerous.

7. Remove all batteries, place them in place, and start installing new batteries.

8. Start from 1# according to the battery number, and start installation from the bottom layer of the battery rack. The position and direction are the same as before. The connector screws must be tightened, the connecting wires are neat and the curvature is consistent. There should be appropriate gaps between batteries, and strict precautions should be taken during the connection process. short circuit.

9. After installing the battery, confirm that the positive and negative poles are correct, measure the total voltage, and confirm that the battery is installed and connected correctly.

10. Calculate the charging voltage based on the battery parameters, and measure the UPS output charging voltage, which meets the charging requirements of this batch of batteries. Close the battery cabinet and check the host charging menu. The battery is already charging.

11. Install the battery cabinet, switch the input of the UPS host back to the mains power, and confirm that the input and output voltage of the UPS uninterruptible power supply host is normal. Stop the generator, disconnect the connecting wires, pack the tools, load the old battery into the truck for transportation back, and clean up the site.
