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

4.6 Optional Features—Liebert XDH

• Smart Module—Smart modules will allow remote shutdown, fan failure alarms and

automatically switching the second fan bank On and Off. The controls save energy by permitting

the module to turn one fan in each fan bank Off based on the supply and return temperature.

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. For electrical connection

details, refer to the Liebert XDH user manual, SL-17210, available on the Liebert Web site:

• Refrigerant Precharge—The Liebert XDH can be precharged with refrigerant. The module will

have one-shot fittings and will 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)—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 style couplings or

removable couplings. Flex pipes with one-shot connections will have pressurized R134a. Flex

pipes with removable connections will have a low pressure nitrogen charge 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 representative.

• Tie-Down Bracket—An optional tie-down bracket may be installed on the Liebert XDH to

secure it in the row. The bracket keeps space between the Liebert XDH and adjacent equipment

constant, preventing vibration.
