Battery Settings
Battery parameter settings greatly affect battery maintenance, battery lifespan, and UPS
discharge time. When you set battery parameters, note the following:

Item Description
voltage exceeds the upper
threshold for the bypass voltage,
the system determines that the
bypass voltage is not normal and
that the bypass is unavailable.
Min. voltage When the difference between the
bypass voltage and the rated
voltage exceeds the upper
threshold for the bypass voltage,
the system determines that the
bypass voltage is not normal and
that the bypass is unavailable.
Frequency When the difference between the
range
bypass input frequency and the
rated frequency is greater than
the specified value, the system
determines that the bypass
frequency is abnormal, so the
bypass is unavailable.
Batt. sharing affects the actual discharge current and the estimated discharge time.
Incorrect settings will cause a high or low charge current, which tends to damage batteries.
An incorrect estimated discharge time may cause a data backup failure.
When Single/Parallel is set to Single, the Batt. sharing parameter is unavailable.
Retain default values for the Cur. Limit coef. and Cell float volt. parameters. Only
professional maintenance personnel can change the values.
