8.3.5Changing Between Floating Charge and Equalized Charge (For HS or AHH individual battery systems)

This section describes the procedure used to change the charging mode. This operation does not apply to shared battery systems.

(1)Table 8.5 shows the procedure used to change manually from floating charge to equalized charge.

The "EQUAL CHARGE" LED lit.

The "FLOAT CHARGE" LED unlit.

*In equalized charge mode, the battery is charged for a set period of time at a voltage about 5% (depending on the type of battery) higher than normal (floating) charge, in order to prevent variations in battery performance. This must be done about once every six months, in spring and autumn if possible.

The TOSNIC-7000S UPS is equipped with a function that performs the equalized charging process automatically when restoring the battery charge after a power outage or the like.
