General safety

Safety information

Observethefollowingruleswhenworkingonelectricalequipments.

• Findtheroomemergencypower‐off(EPO)switch,disconnectingthe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theequipmentthat

hashazardousvoltages.

• Disconnectallpowerbefore:

– Performing a mechanical inspection

– Working near power supplies

– Removing or installing main units

• Beforeyoustarttoworkonthemachine,unplugthepowercord.Ifyou

cannotunplugit,askthecustomertopower‐offthewallboxthatsupplies

powertothemachine,andtolockthewallboxintheoffposition.

• Ifyouneedtoworkonamachinethathasexposedelectricalcircuits,observe

thefollowingprecautions:

– Ensure that another person, familiar with the power-off controls, is near

you.

Attention: Another person must be there to switch off the power, if

necessary.

– Use only one hand when working with powered-on electrical equipment;

keep the other hand in your pocket or behind your back.

Attention: An electrical shock can occur only when there is a complete

circuit. By observing the above rule, you may prevent a current from

passing through your body.

– When using testers, set the controls correctly and use the approved probe

leads and accessories for that tester.

– Stand on suitable rubber mats (obtained locally, if necessary) to insulate

you from grounds such as metal floor strips and machine frames.

Observethespecialsafetyprecautionswhenyouworkwithveryhighvoltages;

instructionsfortheseprecautionsareinthesafetysectionsofmaintenance

information.Beextremelycarefulwhenyoumeasurethehighvoltages.

• Regularlyinspectandmaintainyourelectricalhandtoolsforsafeoperational

condition.

• Donotusewornorbrokentoolsandtesters.

• Neverassumethatpowerhasbeendisconnectedfromacircuit.First,checkit

tomakesurethatithasbeenpoweredoff.

• Donotservicethefollowingpartswiththepoweronwhentheyareremoved

fromtheirnormaloperatingplacesinamachine:

– Power supply units

–Pumps

– Blowers and fans

andsimilarunits.(Thispracticeensurescorrectgroundingoftheunits.)

• Ifanelectricalaccidentoccurs:

– Caution: do not become a victim yourself.

– Switch off the power.

– Send the victim to get medical aid.

Thepurposeofthisinspectionguideistoassistyouinidentifyingpotential

unsafeconditions.Aseachmachinewasdesignedandbuilt,requiredsafety

itemswereinstalledtoprotectusersandservicepersonnelfrominjury.This

Ifanyunsafeconditionsarepresent,youmustdeterminehowseriousthe

apparenthazardcouldbeandwhetheryoucancontinuewithoutfirstcorrecting

theproblem.

Considertheseconditionsandthesafetyhazardstheypresent:

• Electricalhazards,especiallyprimarypower(primaryvoltageontheframe

cancauseseriousorfatalelectricalshock)

• Explosivehazards,suchasadamagedCRTfaceorabulgingcapacitor

• Mechanicalhazards,suchaslooseormissinghardware

Todeterminewhetherthereareanypotentialunsafeconditions,usethe

followingchecklistatthebeginningofeveryservicetask.Beginthecheckswith

thepoweroff,andthepowercorddisconnected.

Checklist:

1. Checkexteriorcoversfordamage(loose,broken,orsharpedges).

2. Turnoffthecomputer.Disconnectthepowercord.

3. Checkthepowercordfor:

a. Athird‐wiregroundconnectoringoodcondition.Useametertomeasure

third‐wiregroundcontinuityfor0.1ohmorlessbetweentheexternal

groundpinandtheframeground.

b. Thepowercordshouldbethetypespecifiedinthepartslist.

c. Insulationmustnotbefrayedorworn.

4. Checkforcrackedorbulgingbatteries.

5. Removethecover.

6. Checkforanyobviousnon‐Lenovoalterations.Usegoodjudgmentastothe

safetyofanynon‐Lenovoalterations.

7. Checkinsidetheunitforanyobviousunsafeconditions,suchasmetalfilings,

contamination,waterorotherliquids,orsignsoffireorsmokedamage.

8. Checkforworn,frayed,orpinchedcables.

9. Checkthatthepower‐supplycoverfasteners(screwsorrivets)havenotbeen

Lenovo TAB3 7 Essential Hardware Maintenance Manual

Anycomputerpartcontainingtransistorsorintegratedcircuits(ICs)shouldbe

consideredsensitivetoelectrostaticdischarge(ESD).ESDdamagecanoccur

whenthereisadifferenceinchargebetweenobjects.ProtectagainstESDdamage

byequalizingthechargesothatthemachine,thepart,theworkmat,andthe

personhandlingthepartareallatthesamecharge.

WhenhandlingESD‐sensitiveparts:

• Keepthepartsinprotectivepackagesuntiltheyareinsertedintotheproduct.

• Avoidcontactwithotherpeople.

• Wearagroundedwriststrapagainstyourskintoeliminatestaticonyour

body.

• Preventthepartfrom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mattoprovideastatic‐freework

surface.ThematisespeciallyusefulwhenhandlingESD‐sensitivedevices.

• Selectagroundingsystem,suchasthoselistedbelow,toprovideprotection

thatmeetsthespecificservicerequirement.

– Attach the ESD ground clip to any frame ground, ground braid, or green-

wire ground.

– When working on a double-insulated or battery-operated system, use an

ESD common ground or reference point. You can use coax or connector-

outside shells on these systems.

– Use the round ground prong of the ac plug on ac-operated computers.

Electricalgroundingofthecomputerisrequiredforoperatorsafetyandcorrect

systemfunction.Propergroundingoftheelectricaloutletcanbeverifiedbya

certifiedelectrician.

RoHS, The Restriction of Hazardous Substances in Electrical and

Electronic Equipment Directive (2002/95/EC) is a European Union legal

requirement affecting the global electronics industry. RoHS requirements

must be implemented on Lenovo products placed on the market after June

2006. Products on the market before June 2006 are not required to have

RoHS compliant parts. If the original FRU parts are non-compliant,

replacement parts can also be non-compliant. In all cases if the original

FRU parts are RoHS compliant, the replacement part must also be RoHS

compliant.
