| with the Battery circuit breaker open, and the mains power fails, |
|
| then the UPS output will also fail together with load power, since |
|
| the inverter has no battery backup. |

|
| power fails then the UPS output will also fail together with load |
|
| power, since there is no battery backup. |

|
12. | BATTERY: TEST FAILED | The system has carried out a test of the battery. If this alarm is not |
|
| accompanied by a [BATTERY C.B. OPEN] or [BATTERY: FUSE FAIL] |
|

|
|
|
13. | DC BUS: UNDERVOLTAGE | When the inverter is operating on the battery this message is |
|
| displayed on the condition when battery voltage has fallen below a |
|
| preset value. If the input a.c. power cannot be restored, you should |
|
| shut down your loads. |
