Questions about Eaton Ellipse ECO 1600 USB IEC

I would wait for the answer from support (Eaton).

The cold current cables must be purchased separately

PLC should stand for Powerline Communication https://de.wikipedia.org/wiki/Powerline_Communication If you do not use PLC, it is not relevant.

You can connect a multiple list without any problems. If you have devices with suitable cables, I would connect them directly, as there is less cable clutter.

Yes

The cable from the unit to the socket has a Swiss plug. The sockets on the unit itself are IEC format, as indicated by the model designation. This UPS is also available with German sockets and French sockets, but not with Swiss sockets. IEC sockets are actually the standard, even with other manufacturers. So you need an IEC to IEC cable to connect your devices. In my opinion, such a cable is already included, the rest you have to get. The UPS has 4 sockets that are supplied with emergency power (at the back) and 4 more that are only protected against overvoltage (at the top). If the 3D printer doesn't eat up a lot of power, the UPS should be big enough for all your devices. I have 2 of this model and 2 other models in use and so far no reason to complain. Eaton's customer service is good. I have replaced all my APCs with Eatons after the electronics of the APCs were defective with amazing regularity (planned obsolescence?).

According to the information on the manufacturer's homepage, the product is only compatible with Windows 7/Vista/XP.
