These terminals provide the 230 V AC supply connection for the control section of the drive when the main power circuit uses a separate air-flow architecture. The X11 designation matches the terminal block on the drive's power board — you're essentially extending that supply point to an external terminal strip for easier wiring access during panel assembly or maintenance.
