Note: All LEDs illuminate during a UPS system self-test.

"ON LINE" LED: This green LED will illuminate continuously to indicate the
UPS system is operating normally in on-line mode (filtering and
resynthesizing AC line input to provide pure sine wave output). When this
LED is illuminated, the load level of the UPS system is displayed on the %
level LEDs (25%, 50%, 75%, 100%).
"LINE" LED: This green LED will illuminate continuously to indicate the
utility-supplied AC line voltage at the wall outlet is nominal. It will flash if
the line voltage is outside the nominal range (either too low or too high).
User action is not required when the LED flashes; the UPS system
continuously and automatically filters AC line power to provide equipment
with pure sine wave AC power, regardless of brownout or overvoltage
conditions. If this LED is off, then AC line voltage is not present (blackout)
or is at an extremely high voltage, and the UPS system will provide
connected equipment with power from its battery system.
"BYPASS" LED: This yellow LED will illuminate continuously when the UPS
system is in economy mode. The LED will flash when the UPS system is
bypass mode, indicating that the UPS system's DC/AC inverter is
deactivated. The red "FAULT" LED will also illuminate if the UPS system is in
bypass mode due to a fault. During normal operation, the bypass LED will
illuminate briefly when the unit is plugged in. If an internal fault or overload
occurs, the LED will flash repeatedly to show that connected equipment will
receive filtered AC line power, but will not receive battery power during a
blackout. In this case, contact Tripp Lite for service.
"FAULT" LED: This red LED will flash when the UPS system detects an
internal fault. If the condition persists after restarting the UPS system, see
Section 6: Troubleshooting.
"LOAD" LED: This green LED will illuminate when the UPS system is
receiving AC power. It also illuminates the % level LEDs (25%, 50%, 75%,
100%) indicating the UPS load level.
"BATT" LED: This green LED will illuminate when the UPS system is
operating from battery power. It illuminates the % level LEDs (25%, 50%,
75%, 100%) indicating the battery charge level. (The "ON BATT" LED will
also be illuminated.)
% Level LEDs: These dual-function LEDs will indicate the % level for either
the load level (if the "LOAD" LED is lit) or the battery charge level (if the
"BATT" LED is lit).
"OVERLOAD" LED: This red LED will illuminate continuously to indicate that
the UPS system's capacity has been exceeded. The UPS alarm will beep
continuously. Immediately unplug some equipment until the LED and alarm
go off. If the overload is not corrected immediately, the UPS system will go
from on-line to bypass mode.
