    Tips: Seven tips for UPS
    1. UPS shall be used in well ventilated, fast radiating and clean environment.
    2. Do not link with inductive load, such as money counter, daylight lamp, air-conditioner so as not to cause damage.
    3. The output load of UPS shall be controlled at 60% for the best and high reliability.
    4. UPS with too light load (for example 1000VA UPS has 100VA load) may cause a deep discharge of the battery, which will reduce the service life of the battery. It should be avoided as much as possible.
    5. Proper discharge can help the activation of batteries. If the electric supply is used for a long time, the electric supply shall be disconnected and use UPS load discharge, which can extend the service life of the battery.
    6. For most small UPS, they should be turned on after starting work. We should avoid starting with load and shut off UPS before off duty. For the UPS of the network machine room, because most of the networks work for 24 hours, UPS shall be operating all day long.
    7. UPS should be charged after discharge in time to avoid damage to the battery due to excessive self discharge.
