On the Schneider Electric website they write 6 watts. I can't measure this because I would have to shut down and reconnect everything.

Thank you very much for letting us know. We will be happy to pass this on internally to the responsible department and hope that this will be checked promptly. Actually, something like this should not happen.

Yes, it will work just fine. The limiting factor will be the 390W total output capability of the UPS. The multi socket of your choice will handle 10A which corresponds to 2'300W. Greetings

This inverter does not appear to be listed as compatible with the DS920+ according to the manufacturer's official list: https://www.synology.com/fr-fr/compatibility?search_by=products&model=DS920%2B&category=upses&p=1&change_log_p=1

Question 1: I have no idea. I have my NAS connected to the mains cable to shut it down automatically (happens automatically between the devices). To question 2: Yes, they are indeed very easy to replace. They are not connected when delivered and have to be connected first. Provided you can get a plug into a socket, the connection should be successful.

According to the product specifications, the following is included: Power cable, 1.83 m USB cable.

Hoi - you can prioritise subjectively (my 8k screen is more important to me than my PC) or by price of purchase (my xykCHF PC is more important to me than my 2.7k screen for xxx CHF) - or by: how fast or difficult will it be to find a replacement for device Z if the worst comes to the worst (e.g. if the insurance, if you have one for something like that, hasn't paid out yet) ... I have e.g. my 3 NAS and the firewall (yes, it's a more abnormal one with many cores and lots of RAM and many interfaces) on the UPS ports, 2 TFT, 2 docking stations, 2 pairs of active speakers on the Surge ports... According to the motto: I can't work without data, restore took a relatively long time, notebook and data are important to me... Find the points that are important to you, then you can rank them. Hope this helps and Lg

Hello, >>>> read the instructions for use. The solutions are on page 2.

In principle, yes. You just have to keep in mind that your old unit has a master-slave function. This one does not. If you don't need this function, you can replace it without any problem.

Hello With me, a battery was included every time. Best regards

There must be something wrong. I would check this with the manufacturer's support. Or maybe Digitec can help here? The runtime at 18% or 60W should usually be at least 5-8 minutes.
