Liebert XD Cooling Modules—Liebert XDCF, Liebert XDH, Liebert XDO, Liebert XDR and Liebert XDV

4.9 Liebert XDO Standard Features

• Micro Channel Heat Exchanger—The Liebert XDO module includes two all-aluminum micro

channel heat exchangers.

• Fan—Air is drawn in the sides of the module through the heat exchangers and is discharged by

the fan to the area below—The Liebert XDO fan tray hinges down to allow access to replace or

service all electrical components.

• Internal Mounting—The Liebert XDO module is typically suspended from the overhead

building structure by inserting field-supplied threaded rods into the internal mounting brackets.

4.10 Optional Features Liebert XDO

• Refrigerant Pre-Charge—The Liebert XDO can be precharged with refrigerant. The module

will have the one-shot fittings and be pressurized. The one-shot Liebert XD Flex Piping will also

be precharged with refrigerant.

• Field-Installed Flexible Piping (for use with prefabricated piping assemblies or port kits)—

Field-installed flexible piping kits are available in lengths of 4, 6, 8 and 10 feet (1.2, 1.8, 2.4 and 3

meters). Connection style to the module end may be straight or 90 degrees with one-shot

connections. Flex pipes with one-shot connections will have pressurized R134a. Connection to the

prefabricated piping assembly is with a threaded coupler. For information on acquiring the

correct kit for your installation, refer to DPN000780, available by calling 1-800-LIEBERT and

from your local Emerson Network Power representative.

• External Mounting Brackets—The Liebert XDO module can be suspended by external

mounting brackets that are attached to the front and rear panels of the module. The external

mounting brackets are optional ship-loose items.

• Smart Modules—The Liebert XDO is available with an optional factory-installed control board.

A Liebert XDO smart module will allow remote monitoring, shutdown, fan failure alarms,

condensate detection and automatically cycling the fan On and Off as the heat load requires.

Liebert XD smart modules are able to provide alarm conditions such as fan failure or condensate

detection at the Liebert XDP display via CANbus communication.

• Lighting Fixture—Field-installable lighting fixtures are available in two voltages, 120V and

277V. The lighting fixture maybe attached to the bottom of the light panel to the left and right of

the fan. Each fixture consists of housing, reflector, ballast and diffuser. Fixtures are compatible

with standard 48" fluorescent bulbs. Bulbs are not included.
