Do not remove the head and disc assembly (HDA) from the drive chassis. Return the entire drive for depot repair if the HDA is defective.

Do not attempt to disassemble the HDA. It is not field repairable. If the sealed HDA is opened by personnel not performing depot repair, this will damage components and void the warranty.

As a component, this drive is designed to be installed and operated in accordance with UL1950, IEC950, EN60950, CSA C22.2 950, and VDE0806. Refer to section 2 for information about installation.

If you do not use a Seagate power supply, ensure that the supply meets the specifications in this manual and is designed to be used in accordance with UL1950, IEC950, EN60950, CSA C22.2 950, and VDE0806.

Seagate takes all reasonable steps to ensure that its products are certifiable to currently accepted standards. Typical applications of these disc drives include customer packing and subsystem design. Safety agencies conditionally certify component parts, such as the Elite disc drive, based on their final acceptability in the end-use product. The subsystem designers are responsible for meeting these conditions of acceptability in obtaining safety/regulatory agency compli- ance in their end-use products and for certifying where required by law. A necessary part of meeting safety requirements is the provision for overcurrent protection on drive SELV supply voltages.

This unit is a component assembly and as such is not meant to comply with FCC or similar national requirements as a stand-alone unit. Engineering radiated and conducted emissions test results are available through the Seagate Safety Department to assist the subsystem designer.
