• The most common battery type used in UPS installations is the valve regulated battery.Valve
regulated cells are not sealed. The amount of gas given off is less than forflooded cells, but when
planning the battery installation, allowance must be made foradequate ventilation and heat
dissipation. Valve regulated cells are not completelymaintenace- free. They must be kept clean and
their connections checked periodicallyto ensure they are tight, and that there is no evidence of
corrosion. It is inevitable thatthe batteries will lose charge during transportation and storage; before
attempting tocarry out an autonomy test, ensure that the batteries are fully charged as this may
takeseveral hours. Cell performance typically improves after a few discharge/rechargecycles.
• The requirements of the EC directives are satisfied when battery cabinet are used withoriginal
accessories. If alternative batteries are used, you must ensure that the appli-cable EC directives are
met and declare conformity.
Connect the battery cabinet as follows:
Turn off the UPS.
Check all the external battery breakers are open.
Connect PE first.
Connect the battery cabinet(s) with cables sized according to cable cross section and protective device
specification to terminals + (positive pole) and - (negative pole).

Special care should be taken when working with the battery cabinet associated with the
equipment. Ensure the battery number is suited to the setting of the battery charging voltage
before installing the battery. When the battery cabinet is connected the overall voltage exceeds
nominal voltage. It is very important to ensure that the batteries are installed separately, in a
dedicated 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.
