Hitachi Ultrastar 15K450 (FC-AL) Hard Disk Drive Specification
29 
9.0  DC Power Requirements
The following voltage specification applies at the drive power connector. Connections to the drive should be made in a safety 
extra low voltage (SELV) circuit. There is no power on or power off sequencing requirement. 
Adequate secondary over-current protection is the responsibility of the system.
