If optional straps areincluded, install the straps as shown in the battery installationdiagram that came with the batteries.Arrange the batteries so there is as much air flow as possiblearound the batteries and so the batteries can be cooled as much aspossible.Some external battery cabinets have cooling slots cut in the shelvesto increase air flow. Arrange the batteries so these slots are notblocked. Some larger batteries must sit with the longest batterydimension in the same direction as the longest shelf dimension.These batteries will partly block the cooling slots. However, if youplace the batteries next to the outside edge of the shelf to leave asmuch space between the batteries as possible, there will be plentyof air flow for cooling.C A U T I O NNever install the batteries in an air-tight enclosure.6.
