E-51028230XT/BG - 9 Operation with the normal AC source restored See figure 9. When normal AC source power (1) is restored or its voltage returns to within specified tolerances, the system automatically returns to its normal operating mode described above (on the condition it did not reach the end of battery power).
10 - E-51028230XT/BG Introduction (cont.) Operation with bypass AC source restored ◗ no battery discharge (see figure 11). When bypass AC source power supply (2) is restored or returns to within specified tolerances, the load is transferred back to the static bypass (C) , without an interruption in the supply of power.
