5. INDICATION AND CONTROL
5.1 Battery level and load level LEDs
The battery level LEDs show the voltage level both in back-up mode and in normal
mode. When the LED indicates 20% of the capacity in back-up mode, it means
that the UPS is going to shut down; for the length of backup time left, it will depend
on the load. While when all five LEDs light in normal mode, it means that the
battery is fully charged.
The load level LEDs show the percentage of added load by the UPS rated capacity.
When all five LEDs light, the UPS is over loaded.
