rack system).
Before and after the installation, if the UPS remains de-energized for a long period, the

UPS must be energized for a period of 24 hours, at least once every 6 months (for a
normal storage temperature less than 25°C). This charges the battery, thus avoiding
possible irreversible damage.
During the replacement of the Battery Module, it is imperative to use the same type and

number of elements as the original Battery Module provided with the UPS to maintain
an identical level of performance and safety.
