27.Line LED (mains status): The green LED lights up when the mains voltage present is within the specified tolerance range. If this LED flashes, either the UPS connection has an incorrect pin assignment (observe phase sequence / neutral conductor connection position) or the mains is outside of the specified tolerance range.
28.to 11. Bar graph LED as the measure of the UPS capacity utilisation or the remaining battery capacity.
These LED’s show the current UPS capacity utilisation when mains voltage is present (normal mode):
11. Orange LED | 96% | – 105% | |
10. Green LED | 76% | – | 95% |
9. Green LED | 56% | – | 75% |
8. Green LED | 36% | – | 55% |
7. Green LED | 0% | – | 35% |
In battery mode, the LED’s indicate the capacity of the batteries:
11. Orange LED | 0% | – | 25% |
10. Green LED | 26% | – | 50% |
9. Green LED | 51% | – | 75% |
8. Green LED | 76% | – | 95% |
7. Green LED | 96% | – 100% | |
12.Fault LED: The red LED lights up with an acoustic warning signal when a fault is present in the UPS system.
