4.0 MECHANICAL CONSIDERATIONS
4.1 Determining Placement in the Conditioned Space
The Liebert XDH units should be placed among the cabinets that generate the greatest amount of
heat. If heat loads are dispersed evenly throughout the room, the Liebert XDH modules may be
spread out accordingly.
The Liebert XDH is engineered to fit among computer enclosure cabinets. Figure 8, below, illustrates
the unit’s dimensions.

4.2 Installing the Liebert XDH Within the Enclosure Row
Built-in casters allow rolling the Liebert XDH into position for installation. Stabilizers reduce the like-
lihood of the unit tipping over. These stabilizers must be removed before the unit is positioned in the
row. Adjustable leveling feet prevent it from moving after positioning.
Once positioned, the Liebert XDH must be secured either to the floor with the included shipping
brackets or to an adjacent cabinet. An adjustable bracket (Liebert P/N 187642G1) for attaching the
Liebert XDH to an adjacent cabinet is included with each unit.
