3.4 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 mounting 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. .528 +/- .015 (13.411 +/- .381) .138 +/- .015 (3.505 +/- .381) 2.750 +/- .010 (69.85 +/- .254) 3.957 +/- .010 (100.5 +/- .254) 0.490 +/- .010 (12.446 +/- .254) 0.680 +/- .010 (17.27 +/- .254) Breather Hole Do not cover or seal. inches (mm) .374 +/- .0078 (9.5 +/- .2) 2X .118 Both sides .551 (13.99) .551 (13.99) 3.567 (90.602) 3.567 (90.60) Recommended case temp. measurement location 2X M3 X 0.5-6H Mounting holes Both sides .12 min. full thread 4X M3 X 0.5-6H Mounting holes .10 min. full thread Figure 4.
