"POWER" LED: this green LED lights continuously when the UPS is ON
and supplying connected equipment with AC power from a utility source.
The LED flashes and an alarm sounds (4 short beeps followed by a pause)
to indicate the UPS is operating from its internal batteries during a
blackout or severe brownout. If the blackout or severe brownout is
prolonged, you should save files and shut down your equipment since
internal battery power will eventually be depleted. See "BATTERY CHARGE"
LED description below.
"VOLTAGE CORRECTION" LED: this green LED lights continuously
whenever the UPS is automatically correcting high or low AC voltage on
the utility line without the assistance of battery power. The UPS will also
emit a slight clicking noise. These are normal, automatic operations of the
UPS; no action is required on your part.
"OUTPUT LOAD LEVEL" LED: this multicolored LED indicates the
approximate electrical load of equipment connected to the UPS's AC
outlets. It will turn from green (light load) to yellow (medium load) to red
(overload). If the LED is red (either illuminated continuously or flashing),
clear the overload immediately by unplugging some of your equipment
from the outlets until the LED changes from red to yellow (or green).
CAUTION! Any overload that is not corrected by the user immediately
may cause the UPS to shut down and cease supplying output power
in the event of a blackout or brownout.
"BATTERY CHARGE" LED: when the UPS is operating from utility power,
this LED indicates the approximate charge state of the UPS's internal
batteries: red indicates the batteries are beginning to charge; yellow
indicates the batteries are roughly midway through charging; and green
indicates the batteries are fully charged. When the UPS is operating from
battery power during a blackout or severe brownout, this LED indicates the
approximate amount of energy (ultimately affecting runtime) which the
UPS's batteries will provide: red indicates a low level of energy; yellow
indicates a medium level of energy; and green indicates a high level of
energy. Since the runtime performance of all UPS batteries will gradually
deplete over time, it is recommended that you periodically perform a self-
test (see MUTE/TEST Button description) to determine the energy level of
your UPS batteries BEFORE a blackout or severe brownout occurs. During
a prolonged blackout or severe brownout, you should save files and shut
down your equipment since battery power will eventually be depleted.
When the LED turns red and an alarm sounds continuously, it indicates the
UPS's batteries are nearly out of power and UPS shut down is imminent.
