2. SafetyPrecautions
2.1. General Guidelines
1. Whenservicing, observetheoriginal leaddress. Ifashortcircuit
isfound, replace all parts whichhavebeenoverheatedor
damagedbytheshortcircuit.
2. Afterservicing, see toitthat all theprotectivedevices suchas
insulation barriers, insulation papersshieldsareproperlyinstalled.
3. Afterservicing, make thefollowing leakagecurrentchecks to
preventthecustomerfrombeing exposedtoshock hazards.
2.1.1. LeakageCurrentColdCheck
1. Unplug theACcordand connect ajumperbetweenthetwoprongs
on theplug.
2. Measuretheresistance value, withanohmmeter, betweenthe
3

jumperedACplug and eachexposedmetalliccabinet parton the
equipmentsuchas screwheads, connectors, control shafts, etc.
Whentheexposedmetallicparthas areturnpathtothechassis,
thereading shouldbebetween1M and 5.2M . / Whenthe
exposedmetal does nothaveareturnpathtothechassis, the
reading must be . Figure1
2.1.2. LeakageCurrentHotCheck (See Figure 1 .)
1. Plug theACcorddirectlyintotheACoutlet. Donotuse an
isolation transformerforthischeck.
2. Connect a1.5k , 10 watts resistor, inparallel witha0.15 F
capacitors, betweeneachexposedmetallicparton theset and a
good earthground suchas awaterpipe, as shownin Figure1.
3. Use anACvoltmeter, with1000 ohms/voltormoresensitivity, to
measurethepotential across theresistor.
4. Check eachexposedmetallicpart, and measurethevoltageat
eachpoint.
5. Reverse theACplug intheACoutlet and repeat eachoftheabove
measurements.
6. Thepotential at anypointshouldnotexceed0.75 volts RMS. A
leakagecurrenttester(Simpson Model 229 orequivalent) maybe
usedtomake thehotchecks, leakagecurrentmust notexceed1/2
milliamp. Incase ameasurementisoutsideofthelimits specified,
thereisapossibilityofashock hazard, and theequipmentshould
berepairedand recheckedbeforeitisreturnedtothecustomer.
3. Prevention of ElectroStaticDischarge (ESD) to
ElectrostaticallySensitive(ES) Devices
Somesemiconductor (solidstate)devices canbedamagedeasilybystaticelectricity. Such
4

componentscommonlyarecalledElectrostaticallySensitive (ES)Devices. Examples oftypical
ES devices areintegratedcircuitsand somefield-effecttransistorsand semiconductor "chip"
components. Thefollowing techniques shouldbeusedtohelpreduce theincidence of
componentdamagecausedbyelectro staticdischarge(ESD).
1. Immediatelybeforehandling anysemiconductorcomponentor
semiconductor-equippedassembly, drainoff anyESDon your
bodybytouching aknownearthground. Alternatively, obtainand
wearacommerciallyavailabledischarging ESDwrist strap,
whichshouldberemovedforpotential shock reasonspriorto
applying powertotheunitundertest.
2. Afterremoving anelectrical assemblyequippedwithES devices,
place theassemblyon aconductivesurface suchas alminumfoil,
topreventelectrostaticchargebuildup orexposureofthe
assembly.
3. Use onlyagrounded-tipsoldering iron tosolderorunsolderES
devices.
4. Use onlyananti-staticsolderremoval device. Somesolder
removal devices notclassifiedas "anti-static(ESDprotected)"can
generate electrical chargesufficienttodamageES devices.
5. Donotuse freon-propelledchemicals. These cangenerate
electrical charges sufficienttodamageES devices.
6. DonotremoveareplacementES device fromits protective
packageuntil immediatelybeforeyou arereadytoinstall it. (Most
replacementES devices arepackagedwithleadselectrically
shortedtogetherbyconductivefoam, alminumfoil or
comparableconductivematerial).
7. Immediatelybeforeremoving theprotectivematerial fromthe
leadsofareplacementES device, touchtheprotectivematerial to
thechassisorcircuitassemblyintowhichthedevice will be
installed.
Caution
Besureno powerisappliedtothechassisorcircuit, and observe
all othersafetyprecautions.
8. Minimizebodilymotionswhenhandling unpackagedreplacement
ES devices. (Otherwise hamless motion suchas thebrushing

todamageanES device).
4. About lead free solder(PbF)
Note:Leadislistedas (Pb)intheperiodictableofelements.
Intheinformation below, Pbwill refertoLeadsolder, and PbF will refertoLeadFree Solder.
TheLeadFree Solderusedinour manufacturing process and discussedbelowis(Sn+Ag+Cu).
ThatisTin(Sn), Silver(Ag)and Copper(Cu)although othertypes areavailable.
Thismodel uses PbFree solderinit’smanufactureduetoenvironmental conservation issues.
For service and repairwork, we’dsuggesttheuse ofPbfree solderas well, although Pbsolder
may beused.
PCBsmanufacturedusing leadfree solderwill have thePbF withinaleafSymbol
stampedon theback ofPCB.
Caution
-Pbfree solderhas ahighermelting pointthanstandardsolder.
Typicallythemelting pointis50 ~70 °F(30~40 °C)higher. Please
use ahigh temperaturesoldering iron and set itto700 ±20 °F(370
±10 °C).
-Pbfree solderwill tend tosplashwhenheatedtoo high (about1100
°For600 °C).
Ifyou must use Pbsolder, please completelyremoveall ofthePb
free solderon thepinsorsolderarea beforeapplying Pbsolder. If
thisisnotpractical, besuretoheat thePbfree solderuntil itmelts,
beforeapplying Pbsolder.
-Afterapplying PbF soldertodoublelayeredboards, please check
thecomponentsideforexcess solderwhichmayflow ontothe
opposite side. (see figurebelow)

SuggestedPbfree solder
Thereareseveral kindsofPbfree solderavailablefor purchase. Thisproductuses Sn+Ag+Cu
(tin, silver, copper)solder. However, Sn+Cu(tin, copper), Sn+Zn+Bi (tin, zinc, bismuth)soldercan
alsobeused.
