ZGXT-PB-72V-03 records Power Protection coverage for the external battery cabinet portion of a Vertiv GXT installation. Its 72 V designation aligns the coverage with a 72 V EBC configuration, while the stated term runs through years 1 to 3. It is a coverage item for the battery cabinet, not a UPS chassis specification or a battery-voltage conversion component. Use this coverage selection where GXT runtime is extended by an external battery cabinet and that cabinet operates at 72 V. Match the service selection to the battery cabinet voltage and EBC scope. A GXT installation can contain a UPS chassis and one or more external battery cabinets, so the battery-cabinet coverage must be considered separately from coverage associated with the UPS frame. The years 1 through 3 designation identifies the covered service period for this 72 V EBC selection. This makes the voltage, equipment scope, and term the three key matching details: GXT family equipment, a 72 V external battery cabinet, and coverage spanning the first three years. It does not establish UPS capacity, runtime, output voltage, outlet count, or battery chemistry because those characteristics belong to the associated UPS and battery hardware.
