Parallel Configurations

The Liebert® EXL™ can be connected with up to 8 units in parallel, where single units can be serviced while the remaining units
continue to power the load. A Liebert® EXL™ unit continues to operate even while it’s being upgraded to a parallel system due to
the upgrade occurring via software settings. Furthermore, Liebert® EXL™ is backward compatible with the previous 80-NET
generation, so as to facilitate any legacy system power upgrade. Liebert® EXL™ can support both distributed and centralized
parallel configurations providing maximum energy saving via double conversion and intelligent ECO mode, allowing to operate with
a system efficiency of up to 99%.

Distributed Parallel Configuration
