fire hazard.
4. Do not allow water or other liquids to spill into the system, this can cause electric shock. Do not allow paper
clips, pins, or other foreign objects to fall into the system as these could cause a short circuit leading to electric
shock or fire hazard.
5. Never touch the plugs on either end of the power cable with wet hands, this can cause electric shock. When
servicing the system, remove the power plug from the wall socket.
6. Use caution when inserting or removing the power connector. The po wer connector must be inserted
completely otherwise poor contact could cause overheating possibly leading to a fire. When remo ving the
power connector, grip it firmly and pull.
7. Do not allow the power cable to become twisted, bent sharply around corners or become damaged. Do not
place objects on top of the power cable. If the power cable is damaged, it can overheat and cause a fire or
exposed cables can cause electrical shock. Replace a damaged power cable immediately , do not reuse or repair
the damaged cable. Some chemicals can eat through the coating on the power cable, weakening the cover, or
exposing cables causing fire and shock risks.
8. Ensure that the power sockets and plugs are not cracked or broken in any way. Any defects should be repaired
or replaced immediately. Take care not to cut or damage the power cable or plugs when moving the system.
9. Use caution during thunder or lightening storms. Xerox recommends that this system be disconnected from the
power source when these weather conditions are present. Do not touch the system or the po wer cord if it is still
connected to the wall socket in these weather conditions.
10. Avoid damp or dusty areas, install the system in a clean well ventilated location. Do not position the system
near a humidifier. Damp and dust build up inside the system can lead to overheating and cause a fire.
11. Do not position the system in direct sunlight. This will cause the temperature inside the system to rise leading
to the system failing to work properly and in extreme conditions could lead to a fire.
12. Do not insert any metal objects into the system through the ventilator fan or other parts of the casing, it could
come into contact with a high voltage conductor inside the system and cause an electric shock.

Precautions
1.3 ESD Precautions
Some semiconductor components, and the respective sub-assemblies that contain them, are vulnerable to damage
by Electro-Static Discharge (ESD). These components include Integrated Circuits (ICs), Large-Scale Integrated
circuits (LSIs), field-effect transistors, and other semiconductor chip components. The following techniques will
reduce the occurrence of component damage caused by static electricity.
Be sure the power is off to the chassis or circuit board, and observe all other safety precautions.
■Immediately before handling any semiconductor components assemblies, drain the electrostatic charge from
your body. This can be accomplished by touching an earth ground source or by wearing a wrist strap device
connected to an earth ground source. Wearing a wrist strap will also prevent accumulation of additional bodily
static charges. Be sure to remove the wrist strap before applying power to the unit under test to avoid potential
shock.
■After removing a static sensitive assembly from its anti-static bag, place it on a grounded condu ctiv e surf ace. If
the anti-static bag is conductive, you may ground the bag and use it as a conductive surface.
■Do not use freon-propelled chemicals. These can generate electrical charges sufficient to damage some
devices.
■Do not remove a replacement component or electrical sub-assembly from its protective package until you are
ready to install it.
■Immediately before removing the protective material from the leads of a replacement device, touch the
protective material to the chassis or circuit assembly into which the device will be installed.
■Minimize body motions when handling unpackaged replace ment devices. Motion, such as your clothes
brushing together, or lifting a foot from a carpeted floor, can generate enough static electricity to damage an
electro-statically sensitive device
■Handle IC’s and EPROM’s carefully to avoid bending pins.
■Pay attention to the direction of parts when mounting or inserting them on Printed Circuit Boards (PCB’s).
