“BOOSTING” LED: This yellow light will be lit when the UPS is boosting AC utility power to nominal levels and providing it to connected equipment. The UPS will click faintly when boosting AC power. This is a normal, automatic function of your UPS and no action is required on your part. If your UPS has to boost power frequently, you may be in a poor power area, and should consider obtaining power protection for equipment that is not connected to a UPS.

“ON BATTERY” LED: This yellow light will be lit when your UPS is providing your equipment with battery power. The UPS will also beep every two seconds, unless silenced by the “ON/TEST” Switch.

“BATTERY METER” LEDs: These four green lights show the approximate charge remaining in the UPS battery. If the battery charge is very low, the 25% LED will flash and the UPS alarm will beep every second to warn you that the remaining charge will be depleted quickly by connected equipment.

“LOAD METER” LED: These four green lights show approximate- ly how much of the UPS’s power capacity is used to support the equip- ment connected to the outlets.

“OVERLOAD” LED: This red light will be lit when the power draw of equipment connected to the Battery, Surge and Noise Protected outlets exceeds your UPS’s power capacity. The UPS alarm will beep continuously. Immediately disconnect excess equipment from the outlets until the light and alarm turn off.

“CHECK BATTERY” LED: This red light will be lit if your UPS’s microprocessor detects a battery fault or if the UPS battery is very weakly charged. Let your UPS charge for 8 hours, then run another self-test. If the light stays on, replace the batteries.

SHORT CIRCUIT: If a short circuit occurs, the UPS will stop providing power to connected equipment and the alarm will sound. If this happens, eliminate the short circuit.

OVERTEMPERATURE: If the temperature inside the UPS gets too high, the NORMAL, BOOSTING, TRIMMING and ON BATTERY LEDs will all light at once and the alarm will sound. If this happens, check to make sure the UPS’s ventilation grills are unobstructed and that it is located in a cool, well-ventilated area.

FAULT: If the UPS detects an internal failure, its NORMAL, BOOSTING and TRIMMING LEDs will light and its alarm will sound. If this happens, disconnect the UPS and contact Tripp Lite for service.

AC Outlets: These 15-amp receptacles provide your connected equip- ment with voltage regulated AC output from the AC line during nor- mal operation and from battery power during power failures. These outlets also protect connected equipment against power surges on the AC line. Your UPS is designed to support only computer equipment with battery power. Do not connect equipment with high power demands (like laser printers) to these outlets.

Communications Ports (USB or RS-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.

Accessory Slot: Remove the small cover panel from this slot to install optional accessories to remotely monitor and control your UPS. Refer to your accessory’s manual for installation instructions. Contact Tripp Lite Customer Support for more information, including a list of available SNMP, network management and connectivity products.

TVSS Cover Plate (Select Models Only): Remove this plate to install optional modem/network surge protection modules, available for purchase by special arrangement with Tripp Lite.

Voltage Dip Switch: Matches the UPS System’s output voltage to the input voltage available at the wall outlet. See Quick Installation section for setting instructions. Note: if the Voltage Dip Switch setting does not match your input voltage (if it is set above or below the input voltage), the UPS system will naturally consider the input voltage as a constant overvoltage or undervoltage condition. The UPS system will respond accordingly by automatically adjusting the input voltage to match the Voltage Dip Switch setting. This will cause constant, unnecessary wear on the UPS system.
