DANGER
Main Protective Earth (Ground):
This symbol is marked on the frame of the rack.
The PROTECTIVE EARTHING CONDUCTORS should be terminated at that
point. A recognized or certified closed loop connector (ring terminal) should
be used and secured to the frame with a lock washer using a bolt or stud.
The connector should be properly sized to be suitable for the bold or stud,
the locking washer, the rating for the conducting wire used, and the
considered rating of the breaker. The intent is to ensure the frame is
electrically bonded to the PROTECTIVE EARTHING CONDUCTORS. The
hole that the bolt or stud goes into where the terminal conductor and the lock
washer contact should be free of any non-conductive material to allow for
metal to metal contact. All PROTECTIVE EARTHING CONDUCTORS
should terminate at this main protective earthing terminal or at points
marked with . (R010)
Special caution and safety notices
This information describes special safety notices that apply to the system. These
notices are in addition to the standard safety notices supplied and address specific
issues relevant to the equipment provided.
Handling static-sensitive devices
Ensure that you understand how to handle devices that are sensitive to static
electricity.
Attention:
Static electricity can damage electronic devices and your system. To
avoid damage, keep static-sensitive devices in their static-protective bags until you
are ready to install them.
To reduce the possibility of electrostatic discharge, observe the following
precautions:
v
Limit your movement. Movement can cause static electricity to build up around
you.
v
Handle the device carefully, holding it by its edges or frame.
v Do not touch solder joints, pins, or exposed printed circuitry.
v
Do not leave the device where others can handle and possibly damage the
device.
v
While the device is still in its antistatic bag, touch it to an unpainted metal part
of the system unit for at least two seconds. (This action removes static electricity
from the package and from your body.)
v
Remove the device from its package and install it directly into your system,
without putting it down. If it is necessary to put the device down, place it onto
its static-protective bag. (If your device is an adapter, place it component-side
up.) Do not place the device onto the cover of the system or onto a metal table.
