Phase to phase 120V & above, Neutral to Grounding 120 & above

So let me guess how this is connected.
Three phase supply (120V ?) connected to the UPS
Output from the UPS connected to what? Nothing?
Voltmeter connected to UPS output.
What make/model is the UPS and is it online or offline configuration?
