switched on, make sure earthing is properly done and wire and battery polarity are
correctly connected.
2. Keep the ambient temperature between 15°C and 25°C.
3. If the UPS has not been used for a long period, charging is recommended at the
interval of 3 months.
4. Replacement of accumulator batteries requires a match of same type and model with
equal quantity and should follow the instructions given by battery suppliers. Users
