4 Mounting the Drive
Use the M3 or M4 screw to mount the STF series drive .The drive should be securely fastened to a smooth ,flat metal surface the
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 particle particles can get on
the circuity.
Always provide air flow around the drive. When mounting multiple STF drives near each other, maintain at least
2cm of space between drives.
