8.3.5 Changing 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.

Step Procedure LCD/LED Status (After Execution)
1 Check to make sure
that the "FLOAT
CHARGE" LED is lit.
2 Hold down the "FLOAT
/ EQUAL" key (h in
Figure 6.3.1 on page

second.

equalized charge is
complete.
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.
