Stop Byte:

Shutdown command :

Computer: S

UPS: Shut UPS output off in minutes.

The UPS output will be off in minutes, even if the utility is present.

But if the battery under occur before minutes, the output is turned off immediately.

After UPS shut down, the controller of UPS monitors the utility. If the utility is there, the UPS will wait for 10 seconds and connect the utility to output.

is a number ranging from.2, .3, ..., 01, 02,..., to 10. For example : S.3 --- shut out put off in ( .3) minutes
