(3) Environmental temperature
Temperature condition at installed in a cabinet is indicated with ambient temperature measured
3 cm from the disk drive. At designing the system cabinet, consider following points.
Make a suitable air flow so that the DE surface temperature does not exceed 55°C.
An air flow with an adequate wind velocity must be maintained to
deal with much heat generated from the MAC30xxxx.
Reference value: An air flow with a wind velocity of more than
Cool the PCA side especially with air circulation inside the cabinet. Confirm the cooling
effect by measuring temperature of specific ICs and the DE. These measurement results
should be within a criteria listed in Table 4.1.

CAUTION
0.5 m/s is required in an environment at 40°C,
and an air flow with a wind velocity of more
than 1.0m/s in an environment at 45°C (Center
of DE cover 55°C).
