Condition: Battery Low |
|
|
|
On: BYPASS, LINE, LOAD, OVERLOAD | Reduce the load the UPS supports. |
Condition: On Bypass due to Overload |
|
|
|
Flashing: OVERLOAD | Remove the cause of the short circuit |
Condition: Short Circuit | from the UPS output. |
|
|

Condition: Wiring Fault | reversed line and neutral or a missing ground. |
|
|
On: FAULT, 100% | Restart the UPS. If the problem persists, |
Condition: Battery Voltage too High | contact Tripp Lite for repairs. |
|
|
On: FAULT, BYPASS, LINE, 50% | Restart the UPS. If the problem persists, |
Condition: On Bypass due to | contact Tripp Lite for repairs. |
High Output Voltage |
|
|
|
On: FAULT, BYPASS, LINE | Restart the UPS. If the problem persists, |
Flashing: 50% | contact Tripp Lite for repairs. |

|
Low Output Voltage |
|
On: FAULT, BYPASS, LINE, 25%
