4 Mounting the Drive
Use the M3 or M4 screw to mount the SSDC series drive. The Drive should be securely fastened to a smooth, flat metal
surface will help conduct heat away from the chassis. If this is not possible, forced airflow from a fan maybe required to
prevent the drive from overheating.
• Never use the drive in a place where there is no air flow or the surrounding air is more than 40°C
• Never put the drive where it can get wet or where metal or other electrically conductive particles can get on
circuitry
• Always provide air flow around the drive. When mounting multiple SSDC drives near each other, maintain at
least 2cm of space belween drive.
