Mounting the Liebert XDV

5.3.1Hanging Stacked Liebert XDVs from Unistruts

Because the upper Liebert XDV in a stacked arrangement must be positioned farther forward than the lower Liebert XDV, two sets of Unistruts are required. The second set of Unistruts must be installed 9-7/8 inches (251mm) forward of the first set. This arrangement positions the stacked Lie- bert XDVs so that they meet the air-intake criteria shown in Figure 10 and Figure 17.

After installing the Unistruts at the proper location, hang the Liebert XDVs as outlined in 5.2.1 - Suspending the Liebert XDV from Unistruts.

Attach hanger brackets

to each corner of each Liebert XDV. This arrangement permits

mounting from either Unistruts or from overhead structure.
