Liebert XDA User Manual

The XDA is activated by turning on the 
ON/OFF switch on the bottom of the 
unit, near the power cords. All fans 
operate continuously to remove the 
maximum amount of heat from the cab-
inet.
If a power failure should occur on the 
primary power source, the XDA will 
operate from the secondary source until 
the primary power source is restored.
The XDA will continue to operate as 
long as either of the two power sources is available.
The Liebert XDA is essentially maintenance-free. An occasional vacu-
uming at the same time other cabinet equipment is cleaned is ade-
quate.
