With the double redundant UPS system, the primary UPS(A) is backed up by the second UPS(B), which is back up by the Bypass source. The load is normally feed from UPS-A. The load is transferred to the back up, UPS-B, only if UPS-A fails, the static switch is manually operated, or the manual bypass switch is operated. The load is transferred to the bypass if the an overload occurs, if both UPS-A and UPS-B fail or if manually transferred, either static switch or manual bypass switch.
