Table 4: Alarm list displayed in the LCD panel
Alarm 1:
This message indicates that the rectifier is overloaded. The rectifier overload
appears when the input current of any phase is greater than the following ratio:
Iin-ovl = 0.326 x Pout / Vout_p-n
Where
• Iin-ovl is Overload Input Current (A)
• Pout is Rated Output Apparent Power (VA)
• Vout_p-n is Rated Output Voltage phase-to-neutral (V)
Alarm 2:
This message indicates that the inverter is overloaded. The inverter overload
appears either when the output current of any phase is greater than the rated
output current
Iout-ovl = Pout / (Vout_p-n * 3)
Where:
• Iout is rated Output Current (A)
• Pout is Rated Output Apparent Power (VA)
• Vout_p-n is Rated Output Voltage phase-to-neutral (V)
