1. UPS power supply has the first charger
After purchasing the UPS power supply, plug the UPS power 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 is not used for a long time. It should be turned on every 2 to 3 months for 24 hours to make it fully charged, and let the UPS power supply be in the inverter for 2 to 3 minutes to ensure the normal life of the battery. Once the UPS power supply is connected to the mains, the battery pack is charged. Press and hold the power button for more than 1 second to turn on the inverter.
2. Reasonable choice of UPS power supply installation location
A good installation location is very important. The place where the UPS is placed must have good ventilation. Keep away from water, flammable gases and corrosive agents. The ambient temperature should be between 0 and 40 °C. If it is disassembled at low temperature, it may be There is a condensation of water droplets. Once the ambient temperature exceeds 25 degrees, the battery life will be reduced by half for every 10 degrees. At present, the batteries used in UPS power supply are generally maintenance-free sealed lead-acid batteries, and the design life is generally 5 years.
The UPS power supply should not be placed sideways. The air inlet and outlet holes should be kept open. When the load is connected to the UPS power supply, the load must be turned off and then re-wired. Then the load should be turned on one by one. It is strictly forbidden to connect the inductive load such as electric and copier to the UPS. So as not to cause harm. When the UPS power supply is connected to a dedicated socket with over current protection device, the power socket used should be connected to the protection ground; the UPS power output may be charged regardless of whether the input power cable is plugged into the mains socket. To make the UPS power supply have no output, you must first turn off the switch and then cancel the mains supply.
3. Power on and off sequence when using UPS power
The correct power-on shutdown sequence should be to first turn on the UPS power supply to power it, and then turn on the various loads, so as to avoid the damage caused by the instantaneous current impact during start up. In the order of shutdown, the load should be closed first and then closed. UPS. When the mains supply is interrupted by the UPS, you should save your own data and data as soon as possible and then turn off the computer. Otherwise, using the UPS power supply may cause the UPS to ovr discharge, thus shortening the service life of the UPS.
