    More details needed.
    What reading do you get?
    How is everything wired?
    Where are you measuring?

    Are you measuring the output of the UPS?

    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?
