For installation flexibility, Vertiv Liebert GXT4 5-6kVA UPS models allow you to choose from several different input/output power wiring configurations made possible by the use of removable power output distribution boxes (PODs) that simply plug into the rear of the UPS. When the ease of plug-and-play power connections is desired, optional versions of the power distribution box convert Vertiv Liebert GXT4 5-6kVA UPS units to a cord-type input with receptacles for output distribution, and also offers maintenance bypass capability that allows hot-swapping of the entire UPS without interruption of power to the connected load.
