Matters needing attention:

1) the use of UPS environment should pay attention to good ventilation, conducive to heat dissipation, and keep the environment clean.
2) do not bring inductive load, such as currency counter, fluorescent lamp, air conditioning, etc., so as not to cause damage.
3) the output load of UPS is controlled at about 60%, and the reliability is the highest.
4) UPS carrying too light (such as 1000VA UPS band 100VA load) may cause deep discharge of the battery, will reduce the battery life, should be avoided as far as possible.
5) appropriate discharge, contribute to the activation of the battery, such as long-term stop electricity, every three months should be UPS with artificial broken electricity load discharge time, so you can extend the service life of the battery.
6) for the majority of small UPS work, open UPS, boot to avoid load startup, the work should be closed for UPS; the network room UPS, because most of the network is 24 hours of work, so UPS must also be all-weather operation.
7) UPS discharge should be charged in time to avoid damage to the battery due to excessive self discharge.
