If power failure occurs…
The unit returns automatically to start operation automatically with the same condition as just before
the failure when it occurs during operation and is recovered. When I used a backup power supply
for blackout return, but a blackout occurred for need in less than 30 minutes more than 30 minutes as
for the charge time of the backup power supply since I turned on electricity in a device, there is the
thing that a blackout does not return temporarily. The blackout return function operates normally after
it was charged a backup power supply enough because I am not abnormal.
