Liebert XDA User Manual

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 
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.
