Liebert manual Hanging Stacked Liebert XDVs from the Overhead Structure

Mounting the Liebert XDV

5.3.2Hanging Stacked Liebert XDVs from the Overhead Structure

Because the upper Liebert XDV in a stacked arrangement must be positioned farther forward than the lower Liebert XDV, the place where the hangers attach to the overhead structure must be offset accordingly. The second row of attachment locations must be 9-7/8 inches (251mm) forward of the first row of hanger mounting locations. This arrangement positions the stacked Liebert XDVs so that they meet the air-intake criteria shown in Figure 10 and Figure 17.

After determining the proper for attachment to the overhead structure, hang the Liebert XDVs as outlined in 5.2.2 - Suspending the Liebert XDV from Overhead Structures.
