Hi, I use a F2-223 with TOS7.0.1130.

I successfully connected an UPS thru USB and configured it with the TOS interface.
The shutdown after a certain time (I configured 5mn) works like a charm (security mode and then stopped).
However, when I.plug back power to the UPS, nothing happens to the NAS and I have to manually press the "on" button to restart it.
The "automatic power on" option is activated.

Any idea ?

My understanding of auto power on is if the NAS didn't have an UPS attached and lost power. I personally I think the UPS shutting down the NAS is a graceful shutdown.

It may depend on UPS settings which may (possibly) be set independently of the NAS. For example: My APC Smart-ups are setup to wait until battery is back at 15% charge, and/or plus a time delay before it will actually supply power to connected devices. It just depends on what you can do and how it can be done. After the UPS starts supplying power, then the device bios setting may apply (as it sees power actually restored). If the Bios setting it to "Turn Off/stay Off" (or similar), it may not pass power to the operating system. Only when the operating system sees power is any software setting likely to apply.
