3 Voltage Correction LED Green—The UPS is automatically correcting high or low AC voltage on
the utility line without the assistance of battery power. The UPS will emit a
slight clicking noise.

support the equipment connected to the output receptacles.

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.
