rectify faults) and the unit can be started, the unit responds to the startup command.
Step 2 Check that the UPS has transferred to normal mode by viewing the system
running diagram.
●
LCD
Check whether the UPS three-phase output voltage and frequency are normal
based on the real-time data displayed in Status > UPS Output on the LCD.
Use a multimeter to check whether the effective values of the three-phase
output voltage and frequency are normal.
●
WebUI
On the home page of the WebUI, choose Monitoring > Real-time Data. In
the Output area, check the UPS three-phase output voltage and frequency.
If the displayed voltages are incorrect, choose Maint. > Calib. on the WebUI
and expand Power unit. Enter the measured voltages for Ph. A output volt.,
Ph. B output volt., and Ph. C output volt. under Actual Value and click
Submit at the end of each row to commission the voltages.
NO TE
Calibrate all power units one by one.
