PURPOSE:To eliminate useless consumption of battery at the time of power interruption and to eliminate live part of AC 100V in a computer using an uninterruptible power supply. CONSTITUTION:The power interruption processing system for uninterruptible power supply 2 comprises a relay RY1 being excited by an input power supply for the uninterruptible power supply 2, and a relay RY2 being excited upon turn ON of the power supply for a computer system 3. At the time of power interruption, the relay RY1 is not excited and shut down processing is executed based on an OPS interruption signal fed from the uninterruptible power supply 2 thus turning the power supply for CPU OFF. Consequently, normal close contacts ry1, ry2 of the relays close to remote turn OFF the uninterruptible power supply 2. |
