All Indicator Light descriptions apply when the UPS is connected to a live utility power source 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 eventual- ly be depleted. See “BATTERY CHARGE” LED description below.

IEC320-C13/230V

AC Receptacles: Your UPS features IEC320-C13 outlets, and select models also feature IEC320-C19 outlets. These output receptacles provide your con- nected equipment with AC line power during normal operation and battery power during blackouts and brownouts. The UPS protects equipment connected to these receptacles against damaging surges and line noise. If you have a serial or USB connection to your UPS, you can remotely reboot connected equipment by turning the receptacles OFF and ON using Tripp Lite's PowerAlert Software.

“VOLTAGE CORRECTION” LED: this green LED lights continuously whenever the UPS is automatically correcting high or low AC voltage on the

IEC320-C19/230V

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 (ulti- mately 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 bat- teries 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.

“BATTERY WARNING” LED: this LED lights red and an alarm sounds intermittently after you complete a self test (See “MUTE/TEST” Button descrip- tion) 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.

Input Terminal block: Use these terminals to connect the UPS System to utility power. Unscrew and remove the cover over the block for access.

Communications Ports (USB orRS-232): These ports connect your UPS to any workstation or server. Use with Tripp Lite’s PowerAlert Software and included cables to enable your computer to automatically save open files and shut down equipment during a blackout. Also use PowerAlert Software to monitor a wide variety of AC line power and UPS operating conditions. Consult your PowerAlert Software manual or contact Tripp Lite Customer Support for more information. See “USB and RS-232 Serial Communications” in the “Optional Installation” section for installation instructions.

Relay Contact Interface Port: This female DB9 port sends contact-closure signals to indicate line-fail and low battery status. See “Optional Installation” section for installation instructions.

EPO (Emergency Power Off) Port: Your UPS features a EPO port that may be used to connect the UPS to a contact closure switch to enable emergency inverter shutdown. See Optional Connection.

Battery Charge Level Switch: Controls the UPS system’s battery charge rate. If you connect any external batteries, set the Battery Charge Level Switch to the down position. This will increase your UPS’s charger output so the additional bat- teries charge faster. Note: the switch to the right of the Battery Charge Level Switch is inactive and will not affect UPS operation regardless of its position.

CAUTION! DO NOT set the Battery Charge Level Switch to the down position without an external battery connected. There is a risk of damaging the UPS’s internal battery system.
