Remember that the accumulators of the system are discharged after the
measurement, which means that the UPS system must work for a few hours
(at least 5 hours) in the mains and charging operation before it is ready for use
again at approx. 80 %.
If the measurement of the support period is not carried out due to local condi-
tions or directives, we recommend a prophylactic replacement of the accumula-
tors every two years to avoid the risk of an insufficient support period on ac-
count of degenerated accumulators.
