Precautions for Safe Use
When the power is restored while auto shutdown processing is being performed after
the "Settings for automatically stopping the UPS after OS shutdown" have been made.
• If a power failure occurs and then the power is restored while auto shutdown is still in prog-
ress, UPS output will stop temporarily after the set time elapses.
Therefore, after shutdown is finished, do not turn on the computer until the UPS has finished
restarting.
