Mount the drive using the bottom or side mounting holes. If mounting the drive using the bottom holes, ensure not to 
physically distort the drive by attempting to mount it on a stiff, non-flat surface.

The allowable mounting surface stiffness is 80 lb/in (14.0 N/mm). The following equation and paragraph define the allowable 
mounting surface stiffness: 

where K is the mounting surface stiffness (units in lb/in or N/mm) and X is the out-of-plane surface distortion (units in inches 
or millimeters). The out-of-plane distortion (X) is determined by defining a plane with three of the four mounting points fixed 
and evaluating the out-of-plane deflection of the fourth mounting point when a known force (F) is applied to the fourth point.

Signal ground (PCBA) and case ground are connected together in the drive and cannot be separated by the user. The 
equipment in which the drive is mounted is connected directly to the drive with no electrically isolating shock mounts. If it is 
desired for the system chassis to not be connected to the drive ground, the systems integrator or user must provide a 
nonconductive (electrically isolating) method of mounting the drive in the host equipment.

Increased radiated emissions may result if designers do not provide the maximum surface area ground connection between 
system ground and drive ground. This is the system designer’s and integrator’s responsibility.
