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

4.15 Liebert XDV Standard Features

• Micro Channel Heat Exchanger—The Liebert XDV module includes one all-aluminum micro

channel heat exchanger.

• Dual IEC Power Cords and Power Inlets—The Liebert 115V, 60Hz Liebert XDV module is

supplied with two detachable, 10 ft (3m) power cords that attach to two IEC power inlets in the

rear of the module. Each power cord has a NEMA 5-15P (IEC 320-C14) plug at the opposite end.

The Liebert 230V, 60/50 Hz Liebert XDV module is supplied with two non-detachable 10 ft (3m)

power cords. This feature allows the module to be powered by two separate power sources.

• Dual Air Inlets—The Liebert XDV module can be configured to allow air to enter from the rear

grille or the bottom of the module.

• Dual Fans—Airflow is provided by two fans on the front of the module.

• Dual Switches—Controls on the front of the module permit the use of one fan or both fans.

• Liebert Foundation Mounting—Two 1/4-20 cage nuts on the underside of module allow direct

attachment to any Liebert Foundation cabinet; bolts provided with Liebert XDV module.

• Mounting Clips for Non-Liebert Cabinets—The Liebert XDV module is supplied with

mounting clips that allow attachment to a non-Liebert cabinet (some drilling may be required).

4.16 Optional Features—Liebert XDV

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

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

also be precharged with refrigerant.

• External Mounting Brackets—The Liebert XDV can be suspended from the overhead building

structure. The external mounting brackets are ship-loose items.

• 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 or removable

connections. 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 DPN000781, available from Liebert by calling 1-800-LIEBERT and from

your local Emerson Network Power representative.

• Smart Module—Liebert XDV smart modules allow remote shutdown, fan failure alarms and

automatically switching the second fan On and Off. This saves energy by permitting the module

to run with one fan and switching on a second fan when the temperature requires both fans for

cooling. 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 XDV user manual, SL-16626, available on the Liebert Web
