Electrostatic discharge protection
Caution. Removal of circuit boards by personnel not
performing depot repair will damage com-
ponents and may void the warranty.
All drive electronic assemblies are sensitive to static
electricity, due to the electrostatically sensitive devices
used within the drive circuitry. Although some devices
such asmetal-oxide semiconductors are extremely
sensitive,allsemiconductors,aswellassomeresistors
andcapacitors,may bedamagedordegradedbyexpo-
sure to static electricity.
Electrostatic damage to electronic devices may be
caused by the direct discharge of a charged conductor
or by exposure to the static fields surrounding charged
objects.Toavoiddamagingdriveelectronicassemblies,
observe the following precautions when installing or
servicing the drive:

2Elite 9 Installation Guide, Rev. B
•Ground yourself to the drive whenever the drive elec-
tronics are or will be exposed. Connect yourself to
ground with a wrist strap (Seagate part number
12263496).Connectionmaybemadetoanygrounded

•TurnoffthepowerbeforeremovingorinstallingtheDC

•Do not remove any circuit boards from the drive.
•Never use an ohmmeter on any circuit boards.

•Donotremovetheheadanddiscassembly(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 compo-
nents 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 VDE0805.
Seagate takes all reasonable steps to ensure that its
products are certifiable to currently accepted stan-

dards. Typical applications of these disc drives include
customer packaging and subsystem design. Safety
agencies conditionally certify component assemblies,
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
complianceintheirend-useproductsandforcertifying
where required by law. A necessary part of meeting
safety requirements is the provision for overcurrent
protection on drive SELV supply voltages.

command.
5See “Conducted noise immunity” in the
Elite 9 Product
Manual. The specified voltage tolerance includes ripple,
noise, and transient response.
6At power-up, the motor current regulator limits the +12V
current to an average value of less than 4.8A, although
instantaneous peaks may exceed this value. These peaks
should measure 5 msec duration or less.
