Adjusng charging current:
1. In bypass mode, press “Test/UP” buon and “Mute/Down” buon simultaneous for more than 1s to
enter the seng menu.
2. Press the “Mute/Down” buon unl it shows 17 in parameter 1 and press “Enter” buon to adjust the
charging current. (Check 3-7 LCD seng for the details.)
3. In parameter 2, you can select the charging current from 1A to 4A by pressing “Test/UP” buon or
“Mute/ Down” buon. Select the charging current based on the number of baery strings. One string
equals 1A, if the number of baery strings is 2 then set it to 2A, if the baery strings is 3A set it to 3A,
anything 4 strings or more set it to 4A.
4. Conrm the seng by pressing the “ON/Enter” buon.
5. In parameter 3, it is to adjust the charging current according to the deviaon between the actual charg-
ing current and the seng 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 seng
charging current will be added 0.4A as output charging current. Then, conrm this modicaon by press-
ing “ON/Enter” buon. Now, you may press “Test/UP” and “Mute/Down” buons at the same me to exit
the seng mode.
NOTE 1: Be careful that the maximum charging current does not exceed the baery accepted charging current.
NOTE 2: All parameter sengs will be saved only when UPS shuts down normally with internal or external baery
connecon. (Normal UPS shutdown means turning o input breaker in bypass/no output mode).
