5.3.1 Hanging 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.
