Hello. I have a Vess R2600ti. Not long ago I reconnected to a new UPS (uninterruptible power supply). I have 3 power supplies. I decided to connect the power supplies to different UPSs, so that if one backup power source fails, the system will work on the second one. But the problem is that when I started checking this circuit, my vess beeped but did not start, although I thought that it would work on one power supply and report that the second one did not work.
Maybe I'm wrong. Write how the system should work if one power supply fails. The screenshot shows how I connected it to the backup power supply.And one more question: I have 3 power supplies (this can be seen from the screenshot) Which one is the backup power supply? If which power supplies fail, will the system shut down?
