IV. Operating procedure

1. Setting up a good location according to relevant procedures set up a good location, connecting cables in accordance with the corresponding identification

2. After power input is connected, power switch on, confirming the regulator is in the “0” position. Pressing the button “Start”, power of indication lights,then bigin to boost current.

3. Pressing buttion “3 phase UP” and closely watching current meter,  If current imbalance,you can adjust single-phase. A phase Up, A phase Down, B phase Up, B phase Down,C phase Up and C phase Down, until current balance to target value. Press the timer button and start the timer. When the time reaches the set time, the alarm signal will be started

4. After the completion of the test, firstly press the button “3 phase Down”,so that the regulator returns to “0”position, then press the “Stop”button, and then reset the “time” button, remove cables connection.
