Page 7: Introduction
Liebert GXT2-10000RT208 UPSs whether utility power is present or not. For ease and safety of installation, the Liebert GXT2-PP20KRT208 is designed with short-circuit pro- tection and color-coded outlets for the UPS electrical connectors. The Liebert GXT2-PP20KRT208 has three parallel ports to communicate with the UPSs. -
Page 8: System Description
During normal operation with parallel connection of three Liebert GXT2-10000RT208 UPSs, the par- allel POD supplies 20kVA of output power plus redundancy of one 10kVA UPS. With the Liebert GXT2-PP20KRT208 N+1 redundancy design, the failure of one UPS will not affect the functioning of the overall system. -
