Functioning 

6.1

 

Normal Mode 

The UPS typically works in 

Normal mode

: Input mains power is available and its amplitude is within specifications.  

In Normal mode the 

LINE/BATTERY

 led is always on. 

During Normal mode, the UPS recharges the batteries and keeps them in an optimal charging voltage.   

6.2

 

Battery Mode 

The UPS automatically runs in 

Battery mode

 if the AC Input Line voltage amplitude gets out of security limits (in 

case of a black-out or over-voltage/low-voltage): in this case, the UPS supplies the required output power by its 
internal battery and by the Inverter block. 

The UPS automatically returns in Normal mode a few seconds after the AC Input Line is recovered. 

In  Battery  mode  the  UPS  emits  an  acoustic  alarm  signal  every  10  seconds  and  simultaneously  the 

LINE/BATTERY

 

led flashes.  

6.3

 

Low Battery and Automatic Restart 

In  Battery  mode,  ERA  PLUS  indicates  the 

Low  Battery

  condition  whenever  the  battery  reaches  a  charge  level 

allowing connected devices to operate for approximately one more minute.  

During  Low  Battery  condition  the  UPS  emits  an  acoustic  alarm  signal  every  second  and  simultaneously  the 

LINE/BATTERY

 led flashes. 

If  AC  Input  does  not  come  back  on  within  few  minutes,  the  UPS 

shuts-down  automatically

  thus  preventing  the 

batteries from discharging excessively; the UPS stops supplying Output power, deactivates control panel indication 
and goes to a waiting state. Once AC Input comes back on, the UPS

 restarts automatically 

and after some seconds 

it goes back to work in Normal mode. 

After  a  complete  discharge,  the  UPS  needs  4  hours  to  recharge  completely  the  batteries.  The  UPS  recharges 
batteries automatically if it works in Normal mode or if it is off and connected to the AC Input Line.
