Electrostatic discharge protection
Caution. Removal of circuit boards by personnel not
performing depot repair will damage compo-
nents 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 as metal-oxide semiconductors are extremely
sensitive, all semiconductors, as well as some resis-
tors and capacitors, may be damaged or degraded by
exposure 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. To avoid damaging drive electronic assemblies,
observe the following precautions when installing or
servicing the drive:
