1LCD Screen: Provides detailed information about operating conditions, UPS system settings and more. See the next page for a description of the LCD symbols.

2LINE LED: This green LED illuminates continuously to indicate the utility-supplied AC line voltage of the AC supply circuit is nominal. It will flash if the line voltage is outside the nominal range (either too low or too high), but still acceptable. 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 unacceptable level, and the UPS system will provide connected equipment with power from its battery system.

3Bypass LED: 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.

4Parallel Redundancy LED: This green LED illuminates when the UPS system is operating in parallel redundancy mode.

5Economy Mode LED: This amber LED illuminates when the UPS system is operating in economy mode.

6Fault LED: This red LED illuminates when UPS system experiences a fault or other abnormal condition. If the condition persists after restarting the UPS system, refer to Section 9 – Troubleshooting.

7“ON” Button: This button controls these separate functions:

UPS System Power ON

To turn on the UPS system, press this button for approximately one second until the UPS system beeps, then release the button.

Buzzer Silence

To silence the UPS system’s buzzer, press this button and hold it until the UPS system beeps, then release the button.

UPS System Cold Start

To use the UPS system as a stand-alone power source when AC power is unavailable (i.e. during a blackout), press this button and hold it until the UPS system beeps, then release the button. See Section 6-4 – Battery Mode Startup for more information.

8“OFF” Button: This button turns off power to the UPS system’s output. Press this button and hold it until the UPS system beeps, then release it. The battery will continue to charge and the fan will continue to operate even when the output is off. To turn the UPS system off completely, including the battery charger, turn off the UPS system’s utility AC input breaker after pressing the “OFF” switch.

9“Enter” Button: This button confirms changes to the UPS system settings.

10“Function” Button: This button allows access to special functions.

11Previous/Change Setting Button: This button returns to the previous page or changes the UPS system settings, depending on the context.

12Next Button: This button goes to the next page.
