Analysis of the use, maintenance and testing methods of UPS power batteries

Use and maintenance of UPS power battery 1. It is forbidden to connect inductive loads to the UPS output port 2. When using UPS power batteries, strictly abide by the relevant regulations in the product manual or user manual to ensure that the live, neutral, and ground wires are connected Meet the requirements, users are not allowed to change their mutual order at will. 3. Operate strictly in accordance with the correct startup and shutdown sequence. When the load is suddenly loaded or unloaded, the voltage output of the UPS power supply battery will fluctuate greatly, and the UPS power supply will not work normally. 4. It is strictly forbidden to close and open the UPS power supply battery frequently. It is generally required to wait at least 6 seconds after closing the UPS power supply before turning on the UPS power supply. Otherwise, the UPS power supply may enter a startup failure state, that is, the UPS power supply enters a state where there is no mains output and no inverter output. 5. Prohibited Overload usage. The maximum starting load of the UPS power battery is best controlled within 80%Z. If overloaded, the inverter tube will often break down in the inverter state. 6. Battery discharge requirements: Generally, UPS has protective measures for battery discharge. But after the battery is discharged to the protection shutdown, the battery can be restored to a certain voltage, but at this time, restarting is not allowed, otherwise the battery will be over-discharged. The UPS must be recharged before it can be put into normal use. 7. The newly purchased UPS must be charged before it can be put into normal use. Otherwise, the backup time cannot be guaranteed. 8. Regarding the UPS without power failure for a long time, the UPS should be discharged every 3 to 6 months and then recharged. In this way, the battery life can be prolonged. 9. Regarding the long-term storage of the UPS, the UPS should be turned on and charged every 3 to 6 months, otherwise the UPS and the battery will be damaged. 10. Regular maintenance of the UPS power battery. Remove the dust in the machine, measure the voltage of the battery pack, check the fan operation and test and adjust the UPS system parameters, etc. 13. Check whether the control template is normal and whether the operation is consistent. If there is no black screen or garbled characters in the display, you should Replace the UPS power supply as soon as possible. jpg Methods to regularly test the UPS power supply battery 1. Measure the voltage of the UPS power supply battery pack and the voltage of the single battery once a month. If the battery voltage is found to be low or uneven, solve it in time 2. Check the capacity of the battery once a year and activate the battery pack once to average the battery capacity. 3. Check the mains power switching device every year, and take the method of disconnecting the power supply 1 and power supply 2 from the incoming line side to check the incoming line The accuracy of the switching module action to ensure that the switching action is correct. 4. Every year, all switching modules of the UPS shall be inspected regularly, and the mains 1, mains 2, and bypass power sources shall be disconnected from the power inlet side, and the switching module shall be inspected Whether the switching function is accurate, and at the same time verifying whether the inverter function is normal.
