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 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) 
 

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) 

or when the total output active power is greater than the following 

formula:  

 

Pact_out-ovl = Pout x 0,8 
 

Where: 
- Pact_out-ovl is the Overload Output Active Power (W)  

- Pout is Rated Output Apparent Power (VA) 

 

˙

Alarm 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. 

 

˙

Alarm 4: This alarm appears when the inverter output voltage 
phase to neutral in any phase is out of margins over +/-6%.  

 

˙

Alarm 5: This alarm appears when there is an offset voltage higher 
than 5V, in any phase of the inverter output voltage phase to 
neutral. 

 

˙

Alarm 6: When the maintenance bypass switch is ON the UPS 

inverter will not be available.  
 

˙

Alarm 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). 

 

˙

Alarm 8: When the inverter or PFC temperature sensors measure 
temperatures over the programmed values (70ºC by default). 

 

˙

Alarm 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. 

 

˙

Alarm 10: This Alarm 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. 

 

˙

Alarm 11: The UPS is on bypass for any reason. It must be 
restarted by display keypad. 

 

˙

Alarm 12: This is an alarm for parallel systems. It appears when 
some UPS of the parallel system block because the maintenance 

bypass switch of any unit is switched ON. 

 

˙

Alarm 13: This alarm indicates that the CAN BUS #1 fails. This  

communication channel is used for remote control. 

 

˙

Alarm 14: This alarm indicates that the CAN BUS #2 fails. This 
channel is used for data communication between UPS, in a parallel 
system. 

 

˙

Alarm 15: This alarm appears at the estimated end of live of the 
battery bank. The revision and replacement of some batteries will 
be necessary to be done by calling the S.T.S. (Service and 
Technical Support) department.
