• 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 (0.4519 N-m).
• Four (4) threads (0.080 inches, 2.032 mm) minimum screw engagement recommended.
• Avoid excessive drive distortion when mounting. Refer to the following specifications for stiffness/deflection
