2 Power LED

Green—The UPS is on and supplying connected equipment with AC

power.

Flashing green—The UPS is operating from its internal batteries during a

blackout or severe brownout. If the blackout or brownout is prolonged,

save any open files and shut down the connected equipment.

3 Voltage Correction LED

the utility line without the assistance of battery power. The UPS will emit a

slight clicking noise.

4 Output Load Level LED

support the equipment connected to the output receptacles.

Red—Maximum load

Amber—Medium load

5 Battery Charge LED

When the UPS is operating from utility power (the Power LED is green),

the Battery Charge LED indicates the approximate charge state of the

batteries:

• Red—The batteries are beginning to charge.

• Amber—The batteries are midway through charging.

• Green—The batteries are fully charged.

When the UPS is operating on battery power during a blackout or severe

brownout (the Power LED is flashing green), the Battery Charge LED

indicates the approximate amount of remaining battery energy:

• Red—The batteries have a low level of energy.

• Amber—The batteries have a medium amount of energy.

• Green—The batteries have a high amount of energy.

Periodically initiate a self-test ("Initiating a self-test" on page 35) to

determine the energy level of the batteries before a blackout or brownout

occurs.
