|
| This selection defines how your UPS runs when the |
|
| input frequency (from the utility) is outside the |
|
| selected frequency tolerance (set via the I/P F Setting, |
|
| above), but is inside the maximum frequency limits the |
|
| UPS can accept before switching to Battery mode. |
|
| For example: If your 60 Hz UPS is set to the factory |
|
| default window of ±5% before the UPS starts |
|
| regulating the frequency: |
|
| The output frequency tracks the input frequency |
|
| exactly from 57 to 63 Hz. |
|
| If input frequency is between 45 and 57 Hz, or |
|
| between 63 and 65 Hz, the output frequency is |
|
| regulated by the UPS to exactly 60 Hz (±0.5 Hz). |
