Mounting the Liebert XDV

5.3Mounting Liebert XDVs in Stacked Setup

Liebert designed the Liebert XDV to permit mounting the units in a stacked arrangement to increase the system’s heat-removal. Stacking may be done either during the original system or added later to an existing configuration.

Stacking Liebert XDVs is possible when suspending units from either Unistruts or from the overhead structure. Hanger brackets are available in two lengths to ease hanging Liebert XDVs in a stacked arrangement.

The upper Liebert XDV must be positioned forward of the front of its companion Liebert XDV for effi- cient heat removal (see Figure 17).

	Lower Liebert XDV must line up
	with front edge of the cabinet
	(space between Liebert XDV and
	cabinet must be blocked to prevent
	recirculation of cooled air
