level of the UPS in both the mains and battery operation
mode. If the top LED is lit in red and the UPS is emitting
a continous sound signal, this indicates that the UPS has
overloaded. However, if the red LED is blinking and the UPS
is emitting a quick intermittent signal, this indicates a shorting
at the back-up's output.If the UPS malfunctions, it switches off
automatically. The reason for shutdown is indicated by the
combination of LEDs lit (see "Description of the UPS’S
