User’s manual 8 UPS ERA PLUS 900-1.100
6 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.
