4.1Determining 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.

4.2Installing 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.
