Rolling the Cabinet Down the RampFor Internal Use Only4.3 External Battery Cabinet InstallationWARNING• In the event of malfunction, the battery cabinet chassis or battery cabinet frames may become live!.• Special care should be taken when working with the battery cabinet associated with theequipment. Ensure the battery number is suited to the setting of the battery charging voltagebefore installing the battery. When the battery cabinet is connected the overall voltage exceedsnominal voltage. It is very important to ensure that the batteries are installed separately, in adedicated battery cabinet.• Battery back-up time do not exceed one hour, if the battery setting shall be exceeded one hour,consult to the professional personnel.Before connecting the external battery, please read the notice and warning label on the battery cabinet.Connect the battery cabinet(s) with cables sized according to cable cross section and protective devicespecification to terminals + (positive pole) and - (negative pole).Connect the battery cabinet as follows:Turn off the UPS.Check all the external battery breakers are open.Connect PE first.CAUTION• The most common battery type used in UPS installations is the valve regulated battery.Valveregulated cells are not sealed. The amount of gas given off is less than forflooded cells, but whenplanning the battery installation, allowance must be made foradequate ventilation and heatdissipation. Valve regulated cells are not completelymaintenace- free. They must be kept clean andtheir connections checked periodicallyto ensure they are tight, and that there is no evidence ofcorrosion. It is inevitable thatthe batteries will lose charge during transportation and storage; beforeattempting tocarry out an autonomy test, ensure that the batteries are fully charged as this maytakeseveral hours. Cell performance typically improves after a few discharge/rechargecycles.• The requirements of the EC directives are satisfied when battery cabinet are used withoriginalaccessories. If alternative batteries are used, you must ensure that the appli-cable EC directives aremet and declare conformity.
