What are the techniques for using and maintaining UPS power?

1. Reasonable selection of the installation location A good installation location is very important. The place where the UpS is placed must have good ventilation, keep it away from water, flammable gases and corrosive agents, and keep the ambient temperature between 0-40°C, if it is at low temperatures Disassembly and assembly may cause condensation of water droplets. Once the ambient temperature exceeds 25 degrees, the life of the battery will be shortened by half for every 10 degrees increase. The batteries currently used by UpS are generally maintenance-free sealed lead-acid batteries with a design life of 5 years. The UpS power supply should not be placed on its side. Keep the air inlet and outlet unobstructed; when the load is connected to the UpS power supply, the load must be turned off, wired, and then turned on one by one. It is strictly forbidden to connect inductive loads such as electric motors and copiers to the UpS to avoid cause some damages. When connecting the UpS to a special socket with an overcurrent protection device, the power socket used should be connected to the protective ground terminal; regardless of whether the input power cord is plugged into the mains socket, the UpS output may be live. To make UpS no output, you must turn off the switch first, and then cancel the mains supply. 2. Skills for charging for the first time After purchasing a new UpS power supply, plug the UpS into the 220V mains power grid and charge it for at least 12 hours to ensure that the battery is fully charged. Otherwise, the actual available capacity of the battery will be much lower than the nominal capacity of the battery. If the UpS power supply is not used for a long time. It should be turned on for 24 hours every 2 to 3 months to allow it to be fully charged, and the UpS power supply should be in the inverter working state for 2 to 3 minutes to ensure the normal life of the battery. Once the UpS power supply is connected to the mains, it will start to charge the battery pack. Press and hold the power button for more than 1 second to turn on the inverter to turn on the inverter. 3. UpS cannot be left unused for a long time. Excessive discharging of the battery and long-term open circuit of the battery can increase the internal resistance of the battery and deteriorate the charge and discharge performance. Regarding the UpS power supply that has not been used for a long time, before restarting and using, let the UpS power supply use the charging circuit in the machine to charge for 12 hours before connecting to the load. Regarding the backup UpS power supply, it is best to keep the UpS power supply in the inverter every other month. Work in the state for 2 to 3 minutes to activate the battery. In addition, the charging current of the battery must be strictly controlled not to exceed the maximum charging current allowed by the battery. Because the excessive charging current will shorten the service life of the battery. 4. The correct startup and shutdown sequence when using the UpS The correct startup and shutdown sequence should be to turn on the UpS first to supply power, and then turn on each load, so as to prevent the instantaneous current impact at startup from damaging the UpS, and the sequence when shutting down On the contrary, each load should be closed first and UpS should be closed last. When the utility power is interrupted by UpS, you should save your data and information as soon as possible and then turn off the computer, otherwise using the UpS power supply for work may cause the UpS to over-discharge, thereby shortening the service life of the UpS.
