7 BATTERIES
The system guarantees uninterruptible power by using buffer batteries directly connected to
the AC/DC conversion output. A periodical check of the Battery State will prevent unpleasant
mishaps that may occur if there is a power shortage, such as short autonomy or in extreme
cases even non-intervention of the system with consequent load loss. If storing battery
cabinets batteries please remember to recharge them every four months (chapter 6.1.3.1), in
order to guarantee the best maintenance possible.
For transport safety the batteries inside the cabinet are disconnected in some points to
discontinue circuit continuity, therefore you must restore these connections when installing the
batteries.
As already mentioned system autonomy depends on the type of battery used and, above all,
on their capacity.
Battery capacity is expressed in ampere/hour, from this parameter you can work out system
autonomy. This expresses the amount of current delivered in a given time interval, discharging
a storage battery at a given condition (discharge current), until it reaches a set voltage. For
example, a 50 Ah capacity can deliver 2,5 A for 20 hours. Excessively hot temperatures, over
40°C, can drastically reduce battery life, due to plate corrosion caused by an increase of acid
aggressiveness. However, the system has a device, which can reduce working voltage
according to the temperature, thus improving battery life.
