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

4.6.1Header System

The Liebert XDCF module system requires use of the Liebert XD prefabricated piping assembly. The prefabricated piping is compatible with the flex pipe required to attach to the Liebert XDCF modules.

4.7Liebert XDH Standard Features

•Dual Refrigeration Circuits—Each Liebert XDH has two refrigeration circuits, one in the upper half of the unit and one in the lower half. Dual refrigeration circuits permit altering cooling levels in response to server room conditions. The dual refrigeration circuits permits interlaced connection of two refrigerant sources to enhance system reliability.

•Dual Power Cords and Power Inlets—The Liebert XDH is supplied with two (2) detachable power cords 10 ft (3m) long that attach to two IEC power inlets on the rear of the unit. Each power cord has a NEMA 5-15P (IEC 320-C14) plug at the opposite end. The dual power cords allow the unit to be powered by two separate power sources. If the secondary power cord is con- nected to a UPS, the Liebert XDH unit fans will continue to operate if utility power fails.

•Top Piping Access—The Liebert XDH has supply and return piping access on the top of each module. Supply piping connection is 1/2" OD copper pipe, and return piping connection is 7/8" OD copper.

•Corner Stabilizers—A stabilizer in each corner permits rolling the Liebert XDH with greater ease and less chance of tipping.

•Air Diffusers—Two diffusers, one on the upper half of the unit and one on the lower half, enhance flow of cooling air. Uni-directional and bi-directional diffusers are available.

4.7.1Optional Features—Liebert XDH

•Condensate Detection—A Liqui-tect moisture detection device and a contact-closure output are available as factory-installed options. These detect condensation in the Liebert XDH’s catch pan and connect to a monitoring or alarm system. A front panel alarm and indicator alert the user to condensation inside the unit.

•Refrigerant Pre-Charge—Liebert XDH units with the pre-charged refrigerant option will have one-shot style fittings or removable couplings that contain pressurized refrigerant inside the Lie- bert XDH. The fittings ease connection to Liebert XD Piping and filling 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). Con- nection style to the unit end may be straight or 90 degrees. Connection to the prefabricated piping assembly is with a threaded coupler. For information on acquiring the correct kit for your instal- lation, refer to DPN000780, available by calling 1-800-LIEBERT and from your local Emerson Network Power representative.
