1. A certain margin should be reserved for UPS power supply, such as 4kVA load, UPS power supply should be configured with more than 5kVA.
2. The UPS power supply should avoid frequent startup and shutdown, preferably in a long-term startup state.
3. 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, the initial charging current should not be greater than 0.5*C5A (C5 can be calculated from the rated capacity of the battery), and 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. The general charging time is 12 to 24 hours.
4. 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 state. The UPS power supply should be charged and discharged regularly, so as to not only activate the battery, but also check whether the UPS power supply is in normal working condition.
5. Regularly check the UPS uninterruptible power supply, and check the float voltage once a month. If the float voltage is lower than 2.2V, the entire battery should be charged equally.
6. Always wipe the battery with a soft cloth to keep the battery surface clean.
7. Temperature control during the operation of the UPS power supply, because the temperature range during the operation of the UPS power supply is controlled within 20 ° C ~ 25 ° C, so as to prolong the service life of the UPS power supply battery. In an environment without air conditioning, the temperature control of UPS power supply is particularly important.
8. The UPS power supply should be charged immediately after use to restore the battery to its normal state.
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 should not be ignored.
