If AC power supply is interrupted or exceeds the technical parameters provided in
Chapter 8 , the UPS
will use the standby battery to supply power to the load. The power supply from the battery will endure
a specied time or until the AC power supply recovers. In the case of long-time interruption of power
supply, the UPS will allow switching to another power system (e.g., generator) or shut down the loads in
sequence.
