5. SAFETY AND HANDLINGThefollowingprecautionsshouldbeobservedwhenhandlingandworkingwithbatteries.ItisrecommendedyoufollowyourCompany’sSafetyProceduresandPractices.
1. Protectterminalsfromshortingduringtransportation.
2. Neverchargeavisiblydamagedmodule(individual12Vbatteryorbloc).
3. Neverchargeafrozenmodule.
4. Keepsparksorothersourcesofignitionawayfrommodule.
5. Useinsulatedtoolstoreducetheriskofshortingwhileinstallingorremovingmodule.
6. Donotlaytoolsormetalsobjectsonthetopofmodule.
7. Removewatches,ringsandotherjewelrywhenworkingaroundmodules.
8. Eyeprotectionandprotectivefootweararerecommendedandmayberequiredbyyouremployer.
9. Verifycircuitpolarityandstringconnectionsbeforeconnectingtothepowersystem.
10. Useproperliftingtechnique,mechanicalliftingequipmentorassistanceasrequiredwhenremovingorinstallingmodules.
11. DisconnectthemoduleorstringofmodulesfromtheDCpowersystemorcommonDCbuspriortoremoval.
12. Theoperatingareashouldbeventilated.

6. EQUIPMENT FOR INSTALLATION AND REMOVALThefollowingarerecommendedforpersonalprotectionandsafeinstallationorremovalofmodules. 1. Insulatedhandtools. 2. Fireextinguisher. 3. Acidspillkit. 4. Eyeprotection. 5. Eyewash. 6. Mechanicalliftingequipmentmayberequiredincertainapplicationssuchascontrolled environmentalvaults.
7. TRANSPORTATIONModule terminals shouldbeprotected fromshortingduring transportation.Newmodulesshould remain in theoriginalpackagingmaterialtoprotectthecaseandterminalsuntiltheyaretobeinstalled.Shockor‘bruising’causedbydroppingorroughhandlingofamodulecancauseinternaldamagetoplates,inter-cellstraps,orcompromisetheintegrityofthecase.Modulesbeingremovedfromserviceshouldlikewisebeprotectedwhenbeingtransportedfrom the job site or to the recycler. The PWL series is rated ‘NON-SPILLABLE’ and should be so labeled duringshipping.The Safety Data Sheet (SDS) isavailablefordownloadatthefollowinglink:http://www.gsyuasa-es.com
8. DELIVERY INSPECTIONUpon receipt inspect the pallet and packaging for visible damage. Inspect themodule terminals and terminalhardware fordamageormissingparts.Manyshipments include installationkits;applicationspecific installationmanual,terminalboltkits,cableassemblies,lugs,moduletraysormodulestands.Theentireshipmentshouldbeverifiedtoensureallcomponentsassociatedwiththeshipmentarepresent.Ifmissingcomponentsordamageisdiscovered,contactyourfreightcarrierorGYESforinstructions.

10. CHARGINGPerformanceandlifeisinpartinfluencedbythepowersystemandtheoperatingtemperature.Thisisespeciallytrueforbatteriesusedintelecommunicationsstandbyfloatapplications.TheoperatingtemperaturerangeforthePWLseriesis-40°Cto+55°C(shorttermexcursionsto65°Carepermissible).
Floatvoltageandproperlyfunctioningtemperaturecompensationarethekeystolongbatterylife.Therecommendedfloat voltage range at 25°C is found on the product label for eachmodel of thePWL series. High temperaturecompensation begins at 26°C and low temperature compensation begins at 24°C. The exact points at whichtemperaturecompensationbegincanbevariedslightlyaslongasthebatteryiskeptwithintherecommendedfloatrangeadjustedfortemperature.

12. MAINTENANCE AND REPLACEMENT12.1 Routine MaintenanceRoutinemaintenance is not required by GYES. Visual inspection of themodule casing and terminalsmay beincludedaspartofyourCompany’ssiteorpowersystemroutinepractices.Thisvisualinspectionshouldbeusedtoidentifyphysicalabnormalitiessuchascorrosion,swelling,cracking,orleakingwhichindicateaneedforfurthertestingorevaluationofthemodulesandpowersystem.Re-tighteningmoduleterminalhardwareisnotrequired.However,ifyourCompanyrequiresre-torqueaspartofaroutinemaintenance,theterminalsshouldbecarefullytightenedwithatorquewrenchtothespecificationfoundontheproductlabel.
Thelifeofthemoduleisgreatlyinfluencedbythepowersystem.Inallcasesfloatvoltageshouldbesetandadjustedfor temperature (See Section 10 “CHARGING”). In non-environmentally controlled applications, temperaturecompensation is required. It is imperative the power systembe adjusted correctly for float and temperaturecompensationandathermalortemperatureprobeinstalledonthestring.
Theabilityofthepowersystemtocorrectlyadjustthefloatfortemperatureisdependentonthepowersystem’stemperatureorthermalprobe.Moduletemperatureisbestreadbyathermalprobeplacedonthesideofthebatteryfor‘paddletype’probesoronthenegativeterminalfor‘ring-type’probes.Periodicorroutinemaintenanceofthepowersystemisessentialtomaximizinglife.
