I'm looking for some guidance on commissioning the Eaton 9155/9355 UPS systems. I've installed various UPS systems before without formal commissioning and typically haven't run into issues. For example, I've successfully worked with Powerware 9170 models across many sites and even commissioned a 9155 recently without any problems. Usually, the electricians connect everything according to the drawings, verify the voltages, and power it on without complications; the hardest part isn't even the installation—it's configuring the network card.
However, I've encountered a roadblock with this unit; I can't run a battery test or activate the output. The system powers on just fine, and I can access the settings, but it doesn't switch to battery, even though it recognizes the batteries. I've come across a setting for 'battery commissioning test' that's baffling me.
If Eaton has implemented a new requirement to physically change a setting from 0 to 1 on-site, I might have to reconsider my enthusiastic support for their products over competitors like Vertiv. Has anyone here dealt with this issue or has tips on moving forward?

I had a similar experience with the Eaton 9PX 11000 last month. The electricians followed the drawings, but we ran into no output power and couldn't perform a battery test. It turned out there was a 208v/240v selector switch on the back that needed adjusting. Once we flipped it, everything worked perfectly!
Have you tried contacting the vendor you bought it from? They might have specific guidance or could schedule a tech for startup service if you're stuck.
Haha, yeah, I called them and all they did was send over the form to schedule an Eaton technician to come assist. Not the best help!
Thanks for the tip! I’ve double-checked, but I don’t see a selector like that on the 9155. I’ve been caught by these kinds of details before, though!
