Drive mounting

You can mount the drive using four screws in the side-mounting holes or four screws in the bottom-mounting
holes. See Figure 4 for drive mounting dimensions. Follow these important mounting precautions when mount-
ing the drive:
• Allow a minimum clearance of 0.030 inches (0.76 mm) around the entire perimeter of the drive for cooling.
• Use only M3 UNC mounting screws.
• Do not overtighten the mounting screws (maximum torque: 4.0 inch-lb).
• Four (4) threads (0.080 inches) minimum screw engagement recommended.
