d. When preparing electrolyte, always pour acid into water,NEVER water into acid. Failure to follow this precautionwill result in excess heat and violent chemical reactionwhich may cause serious injury to personnel.SECTION 11.0General InformationE. If electrolyte comes into contact with skin or clothing,immediately wash with water and neutralize with a solution of baking soda and water. Secure medical treatment. If electrolyte comes into contact with the eyes,wash or flush with plenty of clean water. Secure medicaltreatment immediately.Caution! Before proceeding with the unpacking, handling,installation and operation of this lead-acid storage battery,the following general information should be reviewed together with the recommended safety precautions.A lead-acid battery is an electro-chemical device containingelectrolyte which is a dilute solution of sulfuric acid andwater. This electrolyte is corrosive and can cause injury.F.lead-acid batteries, when installed, are capable of high voltage which can cause electrical shocks to personnel.All lead-acid batteries, in the course of normal operation,generate gases which could be explosive.G. Promptly neutralize and remove any electrolyte spilledwhen handling or installing cells. Use a baking soda/watersolution (1 lb. per gallon of water) to prevent possibleinjury to personnel.Stationary batteries (when installed) are usually on floatcharge continually, unless on discharge in the event of ACfailure, or on recharge following a discharge.h. Make sure that all battery connections are properly prepared and tightened to prevent possible injury to personnel or failure of system.SECTION 2I.BATTERY WARNING STATEMENTDANGERHIGH VOLTAGEhigh voltages are present on most battery systems.Exercise caution and rEMovE All METAloBJECTS FroM PErSoN when working on oraround battery.J.EXPLOSIVE GASESGases produced by battery can be explosive. do NoTSMoKE, USE AN oPEN FlAME, CrEATE AN ArCor SPArKS IN vICINITy oF BATTEry. WEAr EyEProTECTIoN.Personnel should discharge staticcharges from their person to ground before working onbattery. ventilate well in an enclosed space and whencharging.Whenever possible, when making repairs to chargingequipment and/or batteries, interrupt AC and dC circuitsto reduce the possibility of injury to personnel and damage to system equipment. This is particularly importantwith high voltage systems (110 volts and above).NOTE: If the foregoing precautions are not fully understood,clarification should be obtained from your nearest GNB representative. local conditions may introduce situations notcovered by GNB Safety Precautions. here again, contactthe nearest GNB representative for guidance with your particular safety problem; also refer to applicable federal, state,and local regulations as well as industry standards.Safety PrecautionsA. Wear rubber apron, gloves and safety goggles (or faceshield) when handling, installing, or working with batteries. This will help prevent injury due to splashing orspillage of sulfuric acid.B. Prohibit smoking. Keep flames and sparks of all kinds awayfrom vicinity of storage batteries as liberated or entrappedhydrogen gas in the cells may be exploded,causing injury topersonnel and damage to cells.C. Never place metal tools on top of cells, since sparks due toshorting across cell terminals may result in an explosion ofhydrogen gas in or near the cells. Insulate tool handles toprotect against shorting.Familiarize personnel with battery installation, chargingand maintenance procedures. restrict access to batteryarea, permitting trained personnel only, to reduce thepossibility of injury.K. When maintaining a connected battery string, care mustbe taken to prevent a build-up of static charge. Thisdanger is particularly significant when the worker is electrically isolated, ie. working on a rubber mat or an epoxypainted floor or wearing rubber shoes. Prior to makingcontact with the cell, discharge static electricity by touching a grounded surface. Wearing a ground strap whileworking on a connected battery string is not recommended.ACID BURNSBattery contains SUlFUrIC ACId WhICh CANCAUSE SEvErE BUrNS. Avoid getting in eyes, onskin, or on clothing. In case of contact, flush immediately and thoroughly with clean water. oBTAIN MEdICAlATTENTIoN.2.0Exercise care when handling cells. When lifting strapsand strap spreaders are provided, use them with appropriate mechanical equipment to safely handle cells andavoid injury to personnel.SECTION 33.0Receipt of ShipmentImmediately upon delivery by the carrier, examine for possible damage caused in transit. damaged packing material orstaining from leaking electrolyte would indicate rough handling.1

If such conditions are found, make description notation ondelivery receipt before signing. If cell damage is found, requestan inspection by the carrier and file a damage claim. Also notify local GNB representative of action taken.Storage beyond the above stated periods can result in sulphated plates which can be detrimental to battery life andperformance.The battery should be given its initial charge (see Section8.0) before the end of the above stated storage intervals andrepeated for each additional storage interval.3.1 Concealed DamageIf permanent installation is deferred for an extended timeperiod, the battery may be temporarily connected and maintained on a floating charge (see Section 9).Shortly after receipt (within 15 days), examine all cells for concealed damage. Pay particular attention to packing materialexhibiting damage or electrolyte staining. Perform examinationprior to installation and disposal of packing materials. Cells withelectrolyte levels more that 1/2" below top of plates have suffered probable permanent damage due to plate exposure to air.If this condition or other cell damage is found, request an inspection by the carrier immediately and file a concealed damageclaim. Examine cells for container damage, misaligned elements, broken plates, or any other visible damage.Failure to charge in accordance with the above can void thebattery's warranty.4.4 Dry-Charged BatteriesFor batteries shipped dry-charged, follow special handlingand preparation instructions supplied as well as appropriatesections of this Manual.3.2 Electrolyte LevelsCells are shipped with electrolyte levels about 1/8" below thehigh level line. during shipment, the levels drop due to the lossof gases from internal cell components. The amount of drop inlevel will vary with each type of cell. Electrolyte levels, whenreceived, may range from the high level line to slightly below thelow level line. If this condition exists, make no addition of electrolyte or water at this time (see Section 8.2). If certain cellshave low electrolyte levels, with less than 1/2" of plates exposedto air, add battery grade sulphuric acid of the same specific gravity as the remaining cells; thus bringing low level cells up to theaverage level of other cells.SECTION 55.0 Rack AssemblyAssembly of the battery rack should be completed in accordance with the GNB drawing and/or instructions includedwith the rack.SECTION 66.0 Unpacking and HandlingMost cells are packed in individual corrugated cartons.Some smaller size cells are packed in a master carton containing 2 (two) or 3 (three) cells. Cartons are shipped onwood pallets.SECTION 44.0 Storage Prior to Installation4.1 Storage LocationIf the battery is not to be installed at the time of the receipt, it isrecommended that it be stored indoors in a cool, 60 F (15.6 C)to 90 F (32 C), clean, dry location. do not top load pallets orpossible cell damage may occur. Storage or transport of flooded lead-acid batteries at temperatures exceeding 120 F (49 C)can cause detimental effects on plastic components and batterystate of health which may void warranty.4.2 Parts and AccessoriesPrior to planned installation of battery, the separately packagedparts and accessories should be opened and checked againstshipping invoice for completeness. discovery of missing orincorrect parts during installation may cause delays resultingfrom reordering and shipment of replacements. Store parts insafe location to prevent loss.4.3 Storage IntervalFor batteries shipped wet, fully-charged, the following storageintervals from date of shipment to date of installation and initialcharge should not be exceeded:lead-Antimony Types:Three (3) Monthslead Calcium Types:Six (6) Months2Figure 1

remove material holding cartons to pallets, exercising carewhen cutting banding material to prevent injury. If individualcells are to be moved to another location, do not removecarton at this time. Exercise caution if using a two-wheeledhand truck and, to prevent spillage of electrolyte, do not tiltcell more than 25 degrees from vertical. When cells havebeen brought to the installation sight, remove carton sleeveand top corrugated spacers.7.3 Temperature VariationThe location of rack arrangement should result in no greaterthan 5 F (2.78 C) variation in cell temperatures in a seriesstring at any given time. If a greater variation is found, stepsshould be taken to correct the condition. When uniform celltemperature is maintained, the need for equalizing chargesmay be eliminated or reduced in frequency.do NoT lIFT CEllS By ThEIr TErMINAl PoSTS.Support the cells from the bottom when handling andunpacking. In general, units weighing less than 75 poundsare handled manually, being supported from the bottom.7.4 VentilationIn the operation of lead-acid battery whether it be on initialcharge, float charge, equalizing charge or recharge following a discharge, hydrogen and oxygen gases are produced.This results from electrolysis of the water portion of the electrolyte by the charging current.After removal of outer carton and top spacers, the cell should stillbe resting in the bottom corrugated tray. This tray is designed tobe easily broken away to permit positioning of a lifting strapunder the cell with a minimal amount of cell tilting.ventilation should be provided in the battery room or area toprevent hydrogen, liberated from the cells in service, fromexceeding a 1% concentration. Concentrations above thispercentage can result in an explosive mixture, which couldbe ignited by sparks from adjacent electrical equipment aswell as accidental sparks or open flames introduced by personnel. All air moved by ventilation in the battery room orarea should be exhausted into the outside atmosphere andshould not be allowed to recirculate into other confinedareas.A lifting strap and a strap spreader are furnished for use withmechanical lifting devices, when cells weigh 75 pounds ormore. See Figure 1 which shows typical positioning of strapand spreader. large cells are provided with 2 lifting strapsand a special spreader for stability in handling during installation.Always use lifting straps and spreaders, when provided,together with suitable mechanical lifting devices to preventinjury to personnel or damage to cells.7.5 Placement of CellsIt is assumed at this point that the battery rack has beenassembled. Study the rack layout and wiring drawings todetermine proper location of the positive and negative terminals of the battery; this will establish correct positioning ofthe initial cell on each rack row. Cells are normally installedwith plate edges perpendicular to rack length.Platform lifts of adequate capacity to handle cell weights anddimensions may be used provided they are stable and capable of reaching needed heights and used on smooth andlevel floor conditions.Never slide cells across rough surfaces as severe scratching of plastic container bottom may result in stressing andrupturing of the jar with subsequent loss of electrolyte. At alltimes, exercise care when handling cells to prevent scratching of plastic jars and covers.Measure and mark the center of the rack stringer length.determine the number of cells to be placed in each row.When an odd number of cells are in the row, place the center of the initial cell at the center point of the rack stringerlength.SECTION 7When an even number of cells are in the row, locate the initial cells so that the center of the space between the cellscoincides with the center mark of the stringer length.7.0 Installation7.1 Battery LocationTo reduce friction and facilitate the sliding of cells from platform lift into position on the battery rack, only dow Corning#111 silicone grease is permitted for use.It is recommended that the battery be installed in a clean,cool, dry location. Cells should not be exposed to heatingunits, strip heaters, radiators, steam pipes or sunshinethrough a window. Any of these conditions can cause a serious electrolyte temperature variation among cells within abattery (see Section 7.3).USE OF LUBRICANTS OTHER THANDOW CORNING #111 SILICONE GREASEWILL VOID WARRANTY.7.2 TemperatureA battery location having an ambient temperature of 75 F(24 C) to 77 F (25 C) will result in optimum battery life.Batteries operated in high ambient temperatures will resultin reduced life. Therefore, for longer life and ease of maintenance, locations having cooler ambient temperatures arerecommended. The normal battery operating temperaturesare between 60 F (16 C) and 90 F (32 C).DO NOT USE METAL RODS, SCREWDRIVERS, ETC. THROUGH POST HOLESTO POSITION CELLS AS THIS PRACTICECAN CAUSE SHORTING AND POSTDAMAGE AND WILL ALSO VOID WARRANTY.3

When installing cells on the rack, start at the lower step ortier for stability and safety reasons.on cells using stainless steel bolts, washers and nuts, makesure a washer is placed between the bolt head and connector as well as between the nut and connector with the rollededge against the connector. Never install washers betweenthe connector and the cell post. (See figure 2A).Place cells on the rack so that the positive terminal (marked“ ”) of each cell adjoins the negative terminal (marked “-”) ofthe next cell. The standard spacing between cells is 1/2” atthe top of the jars.Adjacent cells should not touch; nor should any cell contactthe metal rack supports or metal cable conduits. Check forproper alignment and 1/2” spacing between cells. Adjustcell position where necessary. This should be completedbefore installation of intercell connectors.CAUTION!WhEN INSTAllING TErMINAl hArdWArEdo NoT PErMIT ANy ITEMS To FAll INToCEll. IF SUCh MATErIAl rEMAINS IN ThECEll, CoNTAMINATIoN WIll rESUlT,rEQUIrING rEPlACEMENT oF ThE CEll.Use two 1/2” thick pieces of plywood cut to cell width and 1”higher than jar height to expedite positioning of cells. Spacecells by placing one piece between the first cell positionedand the next cell. In positioning the third cell, use the second piece of plywood for spacing. The first piece isremoved and used for the next cell placement, etc.As intercell connectors are installed, adjust them to a levelposition and finger tighten hardware.Afte

do not top load pallets or possible cell damage may occur. Storage or transport of flood-ed lead-acid batteries at temperatures exceeding 120 F (49 C) can cause detimental effects on plastic components and battery state of health which may void warranty. 4.2 Parts and Accessories Prior to planned
