Add extended battery coverage for two 288 V GXT battery configurations over the coverage period spanning years 1 through 5. Vertiv ZGXT-PB-288X-05 is a Power Protection Extended Battery Coverage service designation, rather than an external battery cabinet or a replacement battery assembly. Its 288 V designation aligns the coverage selection with the voltage class of the covered GXT battery equipment. The x2 designation sets this service option apart from a single-quantity coverage selection. It is intended where two qualifying 288 V battery configurations require the same extended battery coverage period. Selecting the voltage and quantity together matters because UPS battery systems are configured around a defined battery-bus voltage and associated battery hardware. This option covers the years 1-5 interval stated for the service. It fits GXT UPS environments that use 288 V battery equipment and require coverage for two configurations rather than one. Confirm the protected battery configuration, its 288 V rating, and the required quantity before assigning this service option. The product is a coverage service and does not add UPS output capacity, runtime, outlets, or battery hardware.
