Ergonomic
When positioning the system unit, monitor and keyboard, take into
account any local or national regulations relating to ergonomic
requirements.
Anti-static precautions
WARNING
Static electricity can cause permanent damage to electronic components.
You should be aware of this risk, and take precautions against the
discharge of static electricity into the computer.
The computer is at risk from static discharge while the top cover is off. This
is because the electronic components of the motherboard are exposed.
Memory modules, expansion cards and replacement processors are
examples of electrostatic sensitive devices (ESSDs).
All work that involves removing the cover must be done in an area
completely free of static electricity. We recommend using a Special
Handling Area (SHA) as defined by EN 100015-1: 1992. This means that
working surfaces, floor coverings and chairs must be connected to a
common earth reference point, and you should wear an earthed wrist strap
and anti-static clothing. It is also a good idea to use an ionizer or humidifier
to remove static from the air.
When installing any upgrade, be sure you understand what the installation
procedure involves before you start. This will enable you to plan your work,
and so minimise the amount of time that sensitive components are exposed.
Do not remove the system unit cover, nor the anti-static bag or wrapping of
any upgrade, until you need to.
Handle static-sensitive items with extreme care. Hold expansion cards and
add-on components only by their edges, avoiding their electrical contacts.
Never touch the components or electrical contacts on the motherboard or
on expansion cards. In general, do not handle static-sensitive items
unnecessarily.
Keep all conductive material, and food and drink, away from your work
area and the open computer.
Thermalcote bonding compound
The thermal bonding compound used between the system processor and its
heat sink can cause skin irritation and stain clothing. Avoid prolonged or
repeated contact with skin. Wash thoroughly with soap and water after
handling. Avoid contact with eyes and inhalation of fumes. Do not ingest.
