The following is a case study of a recent construction project to describe the preparation and installation process for the replacement of UPS batteries.

Preparation for machine room battery ：

1. Organize and determine the installation personnel.

2. Pick up the batch of batteries and a small amount of spare cables from the warehouse and transport them to the server room to remove the battery packaging and place them.

3. Check the battery parameters, check the appearance to ensure no damage, battery terminals without oxidation.

4. Number the batteries and put on the machine label in order.

5. Measure the internal resistance and battery voltage with the internal resistance meter, and record the measurement data of each battery according to the label number.

6. Switch to generator power supply when battery replacement is required, you need to contact a good generator to prevent business interruption due to unexpected power failure of utility power.

Installation steps of the battery in the machine room：

1. The construction personnel bring a set of installation and testing tools (sleeve set, movable wrench, screwdriver, hydraulic pliers, multimeter, etc.) and arrive at the construction site of the server room.

2. Check to make sure the sleeve handle and wrench handle are well insulated.

3. Plug the generator output line to the industrial connector of the backup electricity, start the generator, let the generator run first.

4. Open the battery cabinet to take pictures of the backup, find the output line connected to the ups host and confirm the positive and negative poles.

5. Confirm the generator running is stable, after measure the normal voltage on the switch input end in the distribution cabinet voltage, reverse the switch to the generator side, observe and determine the ups host is running normally, turn off the battery circuit breaker in the battery cabinet.

6. Dismantle the old battery, battery shelf battery from top to bottom section by section to remove the next screw on the connection line connector wrapped with electrical tape, ensure good insulation (this step is very important, do not be lazy), to prevent the positive and negative poles from short circuit, which is dangerous.

7. Remove all the battery, place them well, start installing new batteries.

8. According to the battery number from 1 #, from the bottom of the battery rack to start the installation, location direction and the original, the connector screws must be tightened, the connection line shall be neat, curvature shall be consistent, the battery should be left with appropriate gaps between the connection process to prevent short circuit.

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

10. According to the battery parameters, calculate the charging voltage, measure UPS output charging voltage, ensure that it is in line with the batch of battery charging requirements, close the battery cabinet air switch, check the host charging menu, the battery has been in the charging state.

11. Install the battery cabinet, swtich the ups host input back to the mains supply, to confirm that the ups host input and output voltage is normal. Stop the generator, remove the connection cable, pack up the tools, load the old battery ready to be shipped back, and clean up the site.
