nected to the utility power and if the UPS has been turned on, the UPS keeps charging the
battery and also offers the protective function of charging and discharging.
2. Keep the ambient temperature between 15℃ and 25℃ .
3. If the UPS has not been used for a long period, charging is recommended at the interval
