Basic Operation continued

Indicator Lights (Front Panel)

All Indicator Light descriptions apply when the UPS is plugged into a wall outlet and turned ON.

“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” LEDs: the LEDs indicate the approximate electrical load of equipment connected to the UPS's AC outlets. They 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” LEDs: when the UPS is operating from utility power, the LEDs indicate 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, the LEDs indicate 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 red LED illuminates and an alarm sounds continuously, it indicates the UPS's batteries are nearly out of power and UPS shutdown is imminent.

“BATTERY WARNING” LED: this LED lights red and an alarm sounds intermittently after you initiate a self test (See “MUTE/TEST” Button description) to indicate the UPS batteries need to be recharged or replaced. Allow the UPS to recharge continuously for 12 hours, and repeat the self-test. If the LED continues to light, contact Tripp Lite for service. If your UPS requires battery replacement, visit www.tripplite.com to locate the specific Tripp Lite replacement battery for your UPS.

AG-0020, AG-0021, AG-0022 specifications

Tripp Lite, a leader in power protection and connectivity solutions, offers a range of high-quality surge protectors, including the AG-0022, AG-0020, and AG-0021 models. These surge suppressors are designed to meet the demands of modern electronics, providing essential protection against surges, spikes, and electrical noise that can damage devices and disrupt performance.

The Tripp Lite AG-0022 is a robust surge protector featuring advanced technology that safeguards multiple devices simultaneously. It boasts a high joule rating, which indicates its ability to absorb significant energy surges. The model includes multiple outlets, allowing users to connect several devices while ensuring they are all shielded from potential damage. With a built-in circuit breaker to prevent overloads, users can have peace of mind knowing their devices are secure.

In contrast, the Tripp Lite AG-0020 is designed for users who require a lightweight, compact solution for their power needs. Perfect for workstations and home offices, this model emphasizes portability without compromising on protection. Its sleek design includes keyhole mounting slots for easy installation in various environments. Although smaller in size, the AG-0020 still features a solid joule rating and incorporates EMI/RFI noise filtering technology to enhance the performance of connected devices.

The AG-0021 model combines versatility with exceptional protection features. It is particularly well-suited for sensitive electronics such as computers, televisions, and audio equipment. The AG-0021 includes individual switches for each outlet, allowing users to control power to each device independently. This feature enables energy-saving practices, as users can turn off devices that are not in use. Like its counterparts, the AG-0021 is equipped with a high joule rating and advanced noise filtering technology.

All three models are equipped with diagnostics and LED indicators that provide users with real-time status updates on power and surge protection levels. Additionally, Tripp Lite employs durable materials that ensure longevity and reliability, making these surge protectors a valuable addition to any electronic setup. With their distinct features, the AG-0022, AG-0020, and AG-0021 cater to diverse needs, offering superior protection and enhancing the longevity of valuable electronics in every environment.
