vi P520 Hardware Maintenance Manual

Chapter 1. Read this first: Important safety information
This chapter contains the safety infor ation that you ust be fa iliar with.
Power cords and power adapters
Use only the power cords and power adapters supplied by the product anufacturer. Do not use the ac
power cord for other devices.
The power cords shall be safety approved. For Ger any, it shall be H05VV-F, 3G, 0.75 2, or better. For
other countries, the suitable types shall be used accordingly.
Never wrap a power cord around a power adapter or other object. Doing so can stress the cord in ways that
can cause the cord to fray, crack, or cri p. This can present a safety hazard.
Always route power cords so that they will not be walked on, tripped over, or pinched by objects.
Protect power cord and power adapters fro liquids. For instance, do not leave your power cord or power
adapter near sinks, tubs, toilets, or on floors that are cleaned with liquid cleansers. Liquids can cause a short
circuit, particularly if the power cord or power adapter has been stressed by isuse. Liquids also can cause
gradual corrosion of power cord ter inals and/or the connector ter inals on a power adapter, which can
eventually result in overheating.
Ensure that all power cord connectors are securely and co pletely plugged into receptacles.
Do not use any power adapter that shows corrosion at the ac input pins or shows signs of overheating (such
as defor ed plastic) at the ac input or anywhere on the power adapter.
Do not use any power cords where the electrical contacts on either end show signs of corrosion or
overheating or where the power cord appears to have been da aged in any way.
General safety
Follow these rules to ensure general safety:
• Observe good housekeeping in the area of the achines during and after aintenance.
• When lifting any heavy object:
1. Ensure you can stand safely without slipping.
2. Distribute the weight of the object equally between your feet.
3. Use a slow lifting force. Never ove suddenly or twist when you atte pt to lift.
4. Lift by standing or by pushing up with your leg uscles; this action re oves the strain fro the
uscles in your back.
Attention: Do not atte pt to lift any objects that weigh ore than 16 kg (35 lb) or objects that you
think are too heavy for you.
• Do not perfor any action that causes hazards to the custo er, or that akes the equip ent unsafe.
• Before you start the achine, ensure that other service representatives and the custo er's personnel are
not in a hazardous position.
• Place re oved covers and other parts in a safe place, away fro all personnel, while you are servicing the
achine.
© Copyright Lenovo 2018, 2020 1

• Keep your tool case away fro walk areas so that other people will not trip over it.
• Do not wear loose clothing that can be trapped in the oving parts of a achine. Ensure that your sleeves
are fastened or rolled up above your elbows. If your hair is long, fasten it.
• Insert the ends of your necktie or scarf inside clothing or fasten it with a nonconductive clip, approxi ately
8 centi eters (3 inches) fro the end.
• Do not wear jewelry, chains, etal-fra e eyeglasses, or etal fasteners for your clothing.
Remember: Metal objects are good electrical conductors.
• Wear safety glasses when you are: ha ering, drilling, soldering, cutting wire, attaching springs, using
solvents, or working in any other conditions that ight be hazardous to your eyes.
• After service, reinstall all safety shields, guards, labels, and ground wires. Replace any safety device that
is worn or defective.
• Reinstall all covers correctly before returning the achine to the custo er.
CAUTION:
Keep fingers and other parts of your body away from hazardous, moving parts. If you suffer an injury,
seek medical care immediately.
CAUTION:
Avoid contact with hot components inside the computer. During operation, some components
become hot enough to burn the skin. Before you open the computer cover, turn off the computer,
disconnect power, and wait approximately 10 minutes for the components to cool.
Electrical safety
CAUTION:
Electrical current from power, telephone, and communication cables can be hazardous. To avoid
personal injury or equipment damage, disconnect the attached power cords, telecommunication
systems, networks, and modems before you open the computer covers, unless instructed otherwise
in the installation and configuration procedures.
Observe the following rules when working on electrical equip ent.
Important: Use only approved tools and test equip ent. So e hand tools have handles covered with a soft
aterial that does not insulate you when working with live electrical currents. Many custo ers have, near
their equip ent, rubber floor ats that contain s all conductive fibers to decrease electrostatic discharges.
Do not use this type of at to protect yourself fro electrical shock.
• Find the roo e ergency power-off (EPO) switch, disconnecting switch, or electrical outlet. If an electrical
accident occurs, you can then operate the switch or unplug the power cord quickly.
• Do not work alone under hazardous conditions or near equip ent that has hazardous voltages.
• Disconnect all power before:
– Perfor ing a echanical inspection
– Working near power supplies
– Re oving or installing Field Replaceable Units (FRUs)
2P520 Hardware Maintenance Manual

• Before you start to work on the achine, unplug the power cord. If you cannot unplug it, ask the custo er
to power-off the wall box that supplies power to the achine and to lock the wall box in the off position.
• If you need to work on a achine that has exposed electrical circuits, observe the following precautions:
– Ensure that another person, fa iliar with the power-off controls, is near you.
Remember: Another person ust be there to switch off the power, if necessary.
– Use only one hand when working with powered-on electrical equip ent; keep the other hand in your
pocket or behind your back.
Remember: There ust be a co plete circuit to cause electrical shock. By observing the above rule,
you ay prevent a current fro passing through your body.
– When using a tester, set the controls correctly and use the approved probe leads and accessories for
that tester.
– Stand on suitable rubber ats (obtained locally, if necessary) to insulate you fro grounds such as
etal floor strips and achine fra es.
Observe the special safety precautions when you work with very high voltages; these instructions are in
the safety sections of aintenance infor ation. Use extre e care when easuring high voltages.
• Regularly inspect and aintain your electrical hand tools for safe operational condition.
• Do not use worn or broken tools and testers.
• Never assume that power has been disconnected fro a circuit. First, check that it has been powered-off.
• Always look carefully for possible hazards in your work area. Exa ples of these hazards are oist floors,
nongrounded power extension cables, power surges, and issing safety grounds.
• Do not touch live electrical circuits with the reflective surface of a plastic dental irror. The surface is
conductive; such touching can cause personal injury and achine da age.
• Do not service the following parts with the power on when they are re oved fro their nor al operating
places in a achine:
– Power supply units
– Pu ps
– Blowers and fans
– Motor generators
and si ilar units. (This practice ensures correct grounding of the units.)
• If an electrical accident occurs:
– Use caution; do not beco e a victi yourself.
– Switch off power.
– Send another person to get edical aid.
Safety inspection guide
The intent of this inspection guide is to assist you in identifying potentially unsafe conditions on these
products. Each achine, as it was designed and built, had required safety ite s installed to protect users
and service personnel fro injury. This guide addresses only those ite s. However, good judg ent should
be used to identify potential safety hazards due to attach ent of features or options not covered by this
inspection guide.
If any unsafe conditions are present, you ust deter ine how serious the apparent hazard could be and
whether you can continue without first correcting the proble .
Consider these conditions and the safety hazards they present:
Chapter 1.Read this first: I portant safety infor ation 3

• Electrical hazards, especially pri ary power (pri ary voltage on the fra e can cause serious or fatal
electrical shock).
• Explosive hazards, such as a da aged CRT face or bulging capacitor
• Mechanical hazards, such as loose or issing hardware
The guide consists of a series of steps presented in a checklist. Begin the checks with the power off, and the
power cord disconnected.
Checklist:
1. Check exterior covers for da age (loose, broken, or sharp edges).
2. Power-off the co puter. Disconnect the power cord.
3. Check the power cord for:
a. A third-wire ground connector in good condition. Use a eter to easure third-wire ground
continuity for 0.1 oh or less between the external ground pin and fra e ground.
b. The power cord should be the appropriate type as specified in the parts listings.
c. Insulation ust not be frayed or worn.
4. Re ove the cover.
5. Check for any obvious alterations. Use good judg ent as to the safety of any alterations.
6. Check inside the unit for any obvious unsafe conditions, such as etal filings, conta ination, water or
other liquids, or signs of fire or s oke da age.
7. Check for worn, frayed, or pinched cables.
8. Check that the power-supply cover fasteners (screws or rivets) have not been re oved or ta pered
with.
Handling electrostatic discharge-sensitive devices
Any co puter part containing transistors or integrated circuits (ICs) should be considered sensitive to
electrostatic discharge (ESD). ESD da age can occur when there is a difference in charge between objects.
Protect against ESD da age by equalizing the charge so that the achine, the part, the work at, and the
person handling the part are all at the sa e charge.
Notes:
1. Use product-specific ESD procedures when they exceed the require ents noted here.
2. Make sure that the ESD protective devices you use have been certified (ISO 9000) as fully effective.
When handling ESD-sensitive parts:
• Keep the parts in protective packages until they are inserted into the product.
• Avoid contact with other people while handling the part.
• Wear a grounded wrist strap against your skin to eli inate static on your body.
• Prevent the part fro touching your clothing. Most clothing is insulative and retains a charge even when
you are wearing a wrist strap.
• Use the black side of a grounded work at to provide a static-free work surface. The at is especially
useful when handling ESD-sensitive devices.
• Select a grounding syste , such as those listed below, to provide protection that eets the specific
service require ent.
Note: The use of a grounding syste is desirable but not required to protect against ESD da age.
4P520 Hardware Maintenance Manual

– Attach the ESD ground clip to any fra e ground, ground braid, or green-wire ground.
– Use an ESD co on ground or reference point when working on a double-insulated or battery-
operated syste . You can use coax or connector-outside shells on these syste s.
– Use the round ground-prong of the ac plug on ac-operated co puters.
Grounding requirements
Electrical grounding of the co puter is required for operator safety and correct syste function. Proper
grounding of the electrical outlet can be verified by a certified electrician.
