PRODUCT DESCRIPTION
The Liebert XDA Air Flow Enhancer increases the airflow through
densely populated enclosures, breaking up hot spots within the enclosure 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 Liebert Foundation™ cabinets.
1.1

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 cabinet’s rear door, generally used to discharge heat generated from the
cabinet.
If aisle space is insufficient for exterior mounting, and space is available 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 damage. 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 Liebert 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.

Mounting the XDA on the Exterior of the Rear
Cabinet Door
2.3.1 Prepare to Install the Unit
1. Determine the desired mounting position on the door.

2. Attach the mounting bracket to
the top of the XDA, positioning
the bracket to obtain the
desired mounting height.

the bracket toward the rear of
the unit, with the tabs of the
bracket down and in front of the mounting angles.
4. From the rear of the unit, place screws through the XDA mounting
angles, then through the bracket.
5. Place nuts on the screws and tighten them. The nuts should be
visible from the front of the unit.

2.3.2 Mount the Unit and Attach it to the Cabinet
1. Lift the unit with bracket attached and hang it on the door, as
shown at right. Ensure that the bracket rests safely on top of the
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 middle 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
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

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 determine 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 effectiveness of your XDA, and should be eliminated. Take the following steps
to minimize bypass air and maximize heat removal from the equipment cabinet:
1. Ensure that the cable openings in the raised floor beneath the cabinet are properly sealed. Cool air from precision air conditioning
units should be provided to the inlet side of equipment in the cabinet.
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 purpose 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 scissors.
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.

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 connection points.

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 cabinet.
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 vacuuming at the same time other cabinet equipment is cleaned is adequate.
