I'm preparing for our first planned power outage at a small site with a basic rackmount EasyUPS, which doesn't have a network interface or any advanced features. I want to make sure the UPS stays off during the outage and doesn't automatically turn back on when the building's power is switched on and off throughout the day. Since I'm not very knowledgeable about electrical systems, I'm wondering if the best way to ensure the UPS stays off is to just turn the breaker off until we're ready to turn power back on? It's hardwired in, and I don't have access to where the power cable goes through the ceiling. Any suggestions? Thanks!

Did you even check the manual before asking this?
I’d go with the breaker as well. Makes sense to completely disconnect it.
As will I! Thanks for confirming my thoughts.
You can definitely just turn off the UPS manually, but switching off the breaker is a solid choice too. This way, you ensure no power gets to the UPS during the outage.
Make sure to label the breaker clearly and maybe snap some pics of the panels you can access. It's good to have a record of which breakers are supposed to be on or off, just in case something trips later. Also, if you have any unused breakers, disconnect them to tidy up and spare some space – plus, you might get a bit of scrap for a few drinks later!
Consider unplugging any devices from the UPS. Even though it may still receive power, unplugging them ensures they won’t get any power during the outage.
Definitely go with the breaker and test it beforehand. You don’t want to find out it’s faulty when the power comes back on.
No, I didn't. But the manual does mention a shutdown process. From experience, I’ve seen some basic UPSs automatically turn back on when they detect power. So the breaker seems like the best option!
