1.0 PRODUCT DESCRIPTION  
The Liebert XDA Air Flow Enhancer increases the airflow through  
densely populated enclosures, breaking up hot spots within the enclo-  
sure that can threaten the uptime of your critical systems. Equipment  
fans often produce insufficient flow to push air through the masses of  
data communication wiring at the rear of the enclosure. With an XDA  
placed on the exhaust side of the enclosure (the five high-static fans  
ensure positive air flow), the heat is moved out of the enclosure and  
into the room where it can be removed by the room air conditioning  
system.  
The Liebert XDA is also available as a factory-installed option on Lie-  
bert Foundation™ cabinets.

2.0 INSTALLATION  
The Liebert XDA can be attached to most equipment cabinet doors 60"  
tall or taller. The unit typically is installed on the outside of a cabi-  
net’s rear door, generally used to discharge heat generated from the  
cabinet.  
If aisle space is insufficient for exterior mounting, and space is avail-  
able inside the cabinet, the XDA may be installed on the inside of the  
door.  
2.1  
Equipment Inspection  
Immediately after receiving the shipment, remove the XDA and all  
components from the shipping carton and inspect each item for dam-  
age. Check to see that all parts are included:

Pre-Installation Considerations  
• Verify that the XDA unit voltage matches the available utility  
power. The nameplate with this information is located on the top  
of the unit.  
• Note the XDA’s appearance: the front of the unit bears the Lie-  
bert logo (or label) and long, horizontal slots across the fans; the  
rear of the unit has smaller slots over the fans.  
• The XDA is attached to the cabinet door using screws and nuts.  
In most cases, existing holes in perforated cabinet doors can be  
used to mount the XDA. Horizontal slots in the XDA mounting  
angles provide easy alignment with existing holes in the cabinet  
door.  
• If the desired mounting position places mounting holes over the  
solid portion of the door, mark and drill holes as needed in the  
solid portion of the door, using a 3/16" drill bit.  
NOTE  
Check for interference with the cabinet’s handle/latch. If the  
handle swings toward the center rather than toward the outside  
of the door, it may limit positioning options for the XDA.

top edge of door.  
2. Move the unit sideways into the desired position. Ensure that the  
unit does not interfere with operation of the door latch.  
3. Place screws through the middle and lower mounting holes of the  
XDA mounting angle and then through the door. Place nuts on the  
screws and tighten them.  
4. Remove the nuts that attach the bracket to the unit and remove  
the bracket.  
5. Lean the top of the unit slightly away from the door and remove  
the screws.  
6. Install screws in the top holes in the same manner as in the mid-  
dle and bottom holes. Tighten all nuts and screws.

Mounting the XDA on the Interior of the Rear  
Cabinet Door  
2.4.1 Prepare to Install the Unit  
NOTE  
For mounting inside the cabinet, the mounting angles must  
first be reversed, as described in Steps 1 through 4 below.  
1. Remove the screws on the  
Wider side of mounting  
angle with round holes  
fits against XDA  
sides of the XDA that  
secure the mounting angles  
to the unit.  
2. Remove the mounting  
angles.  
3. Position the angles so their  
mounting surfaces are near  
the front of the XDA. (This  
is the air discharge side,  
which has the Liebert logo  
and longer, horizontal slots  
over the fans.) To reverse  
the position of the mounting  
angles properly, rotate  
them vertically so that the  
tops of the angles are at the  
bottom of the XDA and the  
bottoms are at the top.

4. Reattach the angles using  
the screws removed in  
Step 1 above.  
5. Determine the desired  
mounting position on the  
door. Place the bracket on  
the top of the door with the  
tabs on the outside. (The mounting bracket will be used to deter-  
mine the correct holes for screws attaching the XDA to the cabinet  
door.)  
6. Locate the desired mounting holes on the door for the unit.  
7. From the outside of the door, place screws through the bracket,  
then through the door. Place nuts on the screws and tighten them.  
The nuts should now be visible on the inside surface of the door.

2.4.2 Mount the Unit and Attach It to the Cabinet  
1. Lift the unit onto the door, placing the two mounting holes on the  
top end, over the two screws attached to the door and bracket.  
Place nuts on the screws to hold the unit in place.  
2. On the middle and lower mounting holes, place screws through  
the door and then through the mounting angle. Place nuts on the  
screws. Tighten all nuts.  
3. Remove the nuts from the two top screws (the ones through the  
bracket and door).  
4. Lean the top of the unit slightly away from the door and remove  
the remaining nuts from the top two screws.  
5. Pull out the top two screws and remove the bracket from the door.  
6. Install the screws in the top holes in the same manner as in the  
middle and bottom holes.  
7. Tighten all nuts and screws.  
2.5  
Eliminate Bypass Air  
Air that passes through the XDA but not through the heat-producing  
equipment is known as bypass air. Bypass air reduces the effective-  
ness of your XDA, and should be eliminated. Take the following steps  
to minimize bypass air and maximize heat removal from the equip-  
ment cabinet:  
1. Ensure that the cable openings in the raised floor beneath the cab-  
inet are properly sealed. Cool air from precision air conditioning  
units should be provided to the inlet side of equipment in the cabi-  
net.  
2. Ensure that unused rack mounting positions are blocked off using  
blanking plates. This helps ensure that air entering the cabinet  
flows through the heat-producing equipment.  
3. Block off the remaining open perforated area of the rear door with  
the supplied material. The material provided is 10 mil thick, clear  
polycarbonate plastic and has an adhesive backing. The material  
is in the shipping carton, on top of the protective foam packing.  
4. Ensure that the inside of the door is clean. Do not use general pur-  
pose cleaners or window cleaners—they may leave a residue that  
will prevent the air-blocking material from adhering to the door.  
Use plain water or rubbing alcohol.  
5. Cut the material to the size necessary—it is easily cut with scis-  
sors.  
6. Remove the protective paper from the adhesive side, and apply the  
material to the inside surface of the door. Ensure that all open  
perforations are covered.

3.0 POWER CONNECTIONS  
Connect the power cords to separate power sources (as specified in  
Specifications on page 9), to keep the XDA operating if there is a  
power failure on one circuit. Route the power cords under or over the  
cabinet as needed to the nearest available receptacles. If only one  
power source is available, connect both power cords to this source.  
Separate electrical circuits are recommended. Ensure adequate length  
of the power cords when the door is fully opened. Secure the power  
cords using the cable ties provided.  
3.1  
Routing the Power Cords Through the Door -  
Optional  
The power cords may be routed through an additional hole cut in the  
cabinet door. Special tools are required for this.  
1. At a point several inches below the unit and centered between the  
two power cords, cut or punch a 2-inch diameter hole in the door.  
2. Install the 2-inch plastic power cord bushing to protect the power  
cords from damage.  
3. Route the power cords through the cabinet to the desired connec-  
tion points.

4.0 OPERATION & MAINTENANCE  
The XDA is activated by turning on the  
ON/OFF switch on the bottom of the  
unit, near the power cords. All fans  
operate continuously to remove the  
maximum amount of heat from the cab-  
inet.  
If a power failure should occur on the  
primary power source, the XDA will  
operate from the secondary source until  
the primary power source is restored.  
ON/OFF switch  
(seen from below the XDA)  
The XDA will continue to operate as  
long as either of the two power sources is available.  
The Liebert XDA is essentially maintenance-free. An occasional vacu-  
uming at the same time other cabinet equipment is cleaned is ade-  
quate.
