4.4 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 0.030in (0.76 mm) aroun
d the entire perimeter of the drive for cooling.
• Use only M3 UNC mounting screws.
• Do not overtighten the mounting screws. Maximum torque: 4.0 in-lb (0.4519 N-m).
• Four (4) threads (0.080in, 2.032 mm) minimum screw engagement recommended.
• Avoid excessive drive distortion when mounting. Refer to the
following specifications for stiffness/deflection
