Mechanical Considerations 8 4.0 M ECHANICAL C ONSIDERATIONS 4.1 Determining Placement in the Conditioned Sp ace Liebert XDVs should be placed above or on top of the cabinets that generate the greatest amount of heat. If heat loads are dispersed ev enly throug hout the room, the Lieb ert XDV modules may be spread out accordingly. The Liebert XDV is [...]

Mechanical Considerations 9 4.2 Changing the Air Intake Location The Liebert XDV comes from the fact ory with the air intake on the re ar of the unit. If required for your application, this can be changed so th at th e Liebert XDV takes in heated air from the bottom. This is done more easily and safely bef ore the unit is mounted on a computer cabi[...]

Mounting the Liebert XDV 10 5.0 M OUNTING THE L IEBERT XDV The Liebert XDV module must be securely attached to the top of the computer cabinet or, alterna- tively, suspended above the cabinet.
