Question Is it safe to plug a Schuko extension cord (with a single Schuko outlet) into a UPS ?

[darkking791]

Hello everyone,

I just bought a new UPS (NOD U-2000) for my computer and the rest of my system, which includes an RX 6950XT, R7 5800X3D, 32GB DDR4-3200, a 5TB SSD, a 14TB hard drive, two monitors (32" and 25"), and 2.1 Edifier speakers.

There is one issue: my secondary 25" monitor is too far from the UPS to plug in directly. I thought of using an available extension cord. However, I have read in the past that using extension cords with a UPS isn’t safe—although those warnings referred to plugging the UPS into an extension cord rather than plugging an extension cord into the UPS.
So, my question is: Is it safe to plug an extension cord directly into one of my UPS's rear sockets to power my second monitor?

For clarification, the UPS is plugged directly into the wall outlet, and the extension cord is connected to one of the UPS's rear sockets.
It's not the end of the world if my secondary monitor isn't connected to the UPS, but if possible, I'd like to connect it.

Have you thought about relocating the UPS a little closer to your monitor so you don't need an extension cord?

This is the rear of your UPS?

This is the extension cord you're referring to?

Unfortunately, I can't relocate either the UPS or the monitor.

I run my computers on the end of a extension lead with 12 individually switched sockets plugged into my 1500VA APC UPS. That's enough for 5 PCs, 3 monitors, broadband router, firewall, 10Gbe switch and printer. I don't run more than 3 PCs simultaneously.

Schuko extension leads with the term "UPS" in the description exist, but most of them don't have a Schuko plug on the end that plugs into the UPS.

I did find this one with a Schuko plug rated at 16A 250V:

For a professional 19" rack mount system with a 3000VA UPS I'd suggest this:
