CAUTION
Damage to the Equipment
1. To discharge static electricity from the human body, touch the
frame (grounding) before touching a PCA. This prevents the PCA
from being damaged by static electricity.
2. To prevent electrical damage to the disk drive, turn the power off
before mounting or removing a PCA or connecting or
disconnecting a cable, connector, or plug.
3. Do not turn the power on while removing a PCA. This operation
is required to prevent unexpected or unpredictable operation.
4. Do not use a conductive cleaner to clean a disk drive assembly.
5. Open all ventilation holes to prevent overheating of electric circuits.
2.1.2 Maintenance requirements
(1) Preventive maintenance
Preventive maintenance such as replacing air filters is not required.
CAUTION
Do not open the DE in the field because it is completely sealed.
(2) Service life
The service life under suitable conditions and treatment is as follows. The service life is
depending on the environment temperature. Therefore, the user must design the system cabinet
so that the average DE surface temperature is as possible as low.
• DE surface temperature: 45°C or less 5 years
• DE surface temperature: 46°C to 50°C 4 years
• DE surface temperature: 51°C to 55°C 3 years
• DE surface temperature: 56°C and more Strengthen cooling power so that DE
surface temperature is 55°C or less.
For MAF3364FC model, the heating value
generated by the IDD itself is higher, so that
cooling care is specially required.
Reference value: An air flow with a wind velocity of more than 0.5m/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)
Even if the IDD is used intermittently, the longest service life is 5 years.
