1/UPS power supply should have a certain margin in the selection, such as 4kVA load, UPS power supply should be configured more than 5kVA.
2/UPS power supply should avoid frequent opening and stopping, and it is best to turn on the power for a long time.
3/The newly purchased UPS power supply should be charged and discharged, which is beneficial to extend the service life of the UPS power supply battery. Generally, constant voltage charging is adopted, and the initial charging current should not exceed 0.5*C5A (C5 can be calculated by 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 is unchanged for 3 hours, which proves that the battery is sufficient. The charging time is generally 12 to 24 hours.
4/If the power consumption of the factory has been normal, the UPS power supply will not have a chance to work. The battery may be damaged in the long-term floating state. The UPS power supply should be charged and discharged periodically. This will not only activate the battery, but also verify whether the UPS power supply is working properly. status.
5/Regularly check the UPS power supply and check the floating charge voltage once a month. If the float voltage is lower than 2.2V, the entire battery should be balanced.
6/Always wipe the battery with a soft cloth to keep the battery surface clean.
7/The temperature control during the operation of the UPS power supply is to extend the service range of the UPS power supply to 20 ° C to 25 ° C to extend the service life of the UPS power supply battery. Temperature control of UPS power supplies is especially important in environments where there is no air conditioning.
8/The UPS power should be charged immediately after use to return 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. 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 at high current, the loss on the line can not be ignored.
