1. A certain margin should be left in the selection of UPS power supply. For example, for a load of 4kVA, the UPS power supply should be configured with more than 5kVA.
2. The newly purchased UPS power supply should be charged and discharged, which is beneficial to prolong the service life of the UPS power supply battery. Generally, constant voltage charging is used, and the initial charging current should not exceed 0.5*C5A (C50 is calculated by using the rated capacity of the battery). The voltage of each battery is controlled at 2.30~2.35V to avoid damage to the battery. The charging current remains unchanged for 3 consecutive hours, which proves that the battery is sufficient, and the general charging time is 12 to 24 hours.
3. Regularly check the UPS power supply, and check the floating charge voltage once a month. If the floating charge voltage is lower than 22V, the entire battery pack should be balancedly charged.
4. The UPS power supply should be charged immediately after use to restore the battery to a normal state.
5. The temperature control during the operation of the UPS power supply, so that the temperature range during the operation of the UPS power supply is controlled within 20 ° C ~ 250 to prolong the service life of the UPS power supply battery. In an environment without air conditioning, the temperature control of the UPS power supply is particularly important.
6. The UPS power supply should avoid frequent startup and shutdown, and it is best to keep it on for a long time.
7. Always wipe the battery with a soft cloth to keep the battery surface clean.
8. If the power consumption of the factory has been normal, the UPS power supply has no chance to work, and its battery may be damaged in the long-term floating charge state. The UPS power supply should be charged and discharged regularly, so that not only the battery can be activated, but also the UPS power supply can be checked. normal working condition.
9. The distance from the external battery pack to the UPS power supply should be as short as possible, and the cross-sectional area of the wire should be as large as possible to increase the conductivity of the wire and reduce the power loss on the line, especially when working with high current, the loss on the line cannot be ignored.
