Caution Use only the fastening hardware provided with the ONS 15454 to prevent loosening, deterioration, and
electromechanical corrosion of the hardware and joined material.
Caution When mounting the ONS 15454 in a frame with a nonconductive coating (such as paint, lacquer, or
enamel) either use the thread-forming screws provided with the ONS 15454 shipping kit, or remove the
coating from the threads to ensure electrical continuity.
The shelf assembly comes preset for installation in a 23-inch (584.2 mm) rack, but you can reverse the
mounting bracket to fit the smaller 19-inch (482.6 mm) rack.
