If your distribution doesn't come with a default installation of xfce4-power-manager, it will be started next time you log into your Xfce desktop after you have installed it. In order to start it manually you just need to run the following command xfce4-power-manager from your terminal emulator. Please note that running this xfce4-power-manager command will cause the power manager to run in daemon mode. You can optionally add –no-daemon as a command line argument to disable this behavior. This can be useful if you want to see debugging outputs from your terminal emulator.

The general usage of the command line options is:
