MOUNTING INSTRUCTIONS
The drive should be mounted on a flat surface and located in an area where it will not be exposed to contaminants such as water, metal chips,
solvents, or excessive vibration. When mounting the drive in an enclosure, the enclosure should be large enough to allow proper heat
dissipation so that the ambient temperature does not exceed 40 °C (104 °F) at full rating. Always mount the heat sink vertically, if possible, to
achieve maximum efficiency. Mount the heat sink with the keyhole slots positioned as shown. See Figure 1.
