 Screen 4.1: This alarm 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
- 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)
 Screen 4.2: This alarm 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)
- Iout is rated Output Current (A)
- Pout is Rated Output Apparent Power (VA)
- Vout_p-n is Rated Output Voltage phase-to-neutral (V)
or when the total output active power is greater than the following formula.
Pact_out-ovl = Pout x 0,8
- Pact_out-ovl is the Overload Output Active Power (W)
- Pout is Rated Output Apparent Power (VA)
 Screen 4.3: This alarm appears when the input the unit is under main failure condition and the level
of battery is lower than 11,5V/bat.
 Screen 4.4: This alarm appears when the inverter output voltage phase to neutral in any phase is
out of margins over +/-6%
 Screen 4.5: This alarm appears when there is an offset voltage higher than 5V, in any phase of the
inverter output voltage phase to neutral.
 Screen 4.6: When the maintenance bypass switch is ON the UPS inverter will not be available.
 Screen 4.7: The mains failure occurs when in any phase, the input voltage phase to neutral is out of
the set margins (+15%/–20% by default) or the input frequency is out of the set margins (± 0,5Hz
by default).
 Screen 4.8: When the inverter or PFC temperature sensors measure temperatures over the
programmed values (70ºC by default).
 Screen 4.9: This message appears when the battery switch is OFF and the DC bus is charged to the
battery voltage level, to inform the user to switch ON the battery switch.
 Screen 4.10: This screen indicates that the bypass input voltage or the bypass input frequency are
out of margins. These margins are programmable but by default the bypass voltage range is
+12%/–17% and the bypass frequency range is ±0.5Hz.
 Screen 4.11: The UPS is on bypass for any reason. It must be restarted by display keypad
