Determine the Location of the UPS in the Rack
UPSs are heavy. Select a rack location sturdy enough to handle the weight. Mount the UPS at or near the bottom of the
rack.
Select a rack location with adequate air flow that is free from excessive dust. Ensure that any air vents on the sides of the
UPS are not blocked. Do not operate the UPS where temperature or humidity are outside the limits listed under
Specifications, page 17.
Two additional sets of bracket holes, shown below at asterisks (*), are located on the sides of all rack mount UPS models
except the 5000 VA. These holes allow mounting the brackets with a three inch or six inch setback. Move the mounting
brackets back if desired to optimize the esthetic or physical requirements of the rack. The 5000 VA unit cannot be
mounted in a setback position since it requires the full depth of the rack.

Caution:
Check the rack to make sure it won’t tip after moving the mounting brackets.
1. Determine where in the rack you’ll mount the UPS. The
SU5000 requires a space of 5U. Some racks have tick marks to
indicate the U-spaces.
2. Using the mounting template provided (part number 990-0195),
identify and mark the correct mounting holes for the UPS
mounting brackets.
3. Locate and mark the bottom hole in the designated U-space .
The bottom screw on the mounting rail will attach to the bottom
hole in the U-space.
4. Repeat steps 2 and 3 for the remaining three rack posts.
5. Prepare the rack holes, if necessary. Racks with threaded holes
require no preparation.
If your rack has round holes, insert clip nuts
(provided) into
the holes marked in step 2.
If your rack has square holes, insert either clip
or cage
nuts into the holes marked in step 2.

Align the bottom hole on the mounting rail with the bottom
hole in the U-space (marked in step 3 above). Use the flat,
Phillips head screws (10-32) and conical washers to attach
the front rail to the rack. Position the rails so that the lip of
the rail is on the bottom.
