3. In parameter 2, you can select the charging current from 1A to 4A by pressing “Test/UP” button
or “Mute/ Down” button. Please confirm the setting by pressing “ON/Enter” button.
4. In parameter 3, it is to adjust the charging current according to the deviation between the actual
charging current and the setting value of the current.
For example, you want to have the charging current in 4A, but in fact, the charging current is measured
only 3.6A. Then, you need to select “+” and change the number to 4 in parameter 3. It means the
setting charging current will be added 0.4A as output charging current. Then, confirm this modification
by pressing “ON/Enter” button. Now, you may press “Test/UP” and “Mute/Down” buttons at the same
time to exit the setting mode.
NOTE 1: Be careful that the maximum charging current should not exceed the battery accepted
charging current.
NOTE 2: All parameter settings will be saved only when UPS shuts down normally with internal or
external battery connection. (Normal UPS shutdown means turning off input breaker in bypass/
no output mode).
