Emerson GXT2-PP20KRT208 用户手册

The Liebert GXT2-PP20KRT208 parallel POD is compatible only with the Liebert GXT2-10000RT208 

UPS. No more than three Liebert GXT2-10000RT208 UPSs can be connected to the parallel POD.

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.

When the UPS system must be completely shut down, maintenance bypass allows the parallel POD to 

work in the normal operation without interrupting power to the load. As shown in Figure 1, the Lie-

bert GXT2-PP20KRT208 provides an alternate path for utility power to the connected load. In the 

event that the UPS experiences a failure, the UPS battery runs out or any other condition occurs 

requiring maintenance on the UPS, the user may manually transfer the connected load from the 

inverter to bypass by switching the maintenance bypass breaker to the On position.
