The 5-LED display on the left of the front panel represents the power drawn from the UPS as a percentage of
total capacity. For example, if three LEDs are lit, the load is drawing between 50% and 67% of the UPS’s
capacity. If all five LEDs light, thoroughly test your complete system to make sure that the UPS will not become
overloaded.
Overload
When the UPS is overloaded (the connected loads exceed 5000 VA / 3750 W) , the overload LED comes on and the UPS
emits a sustained tone. The alarm remains on until the overload is removed. Disconnect nonessential load equipment
from the UPS to eliminate the overload.
SmartTrim
This LED comes on to indicate that the UPS is compensating for a high voltage.
SmartBoost
This LED comes on to indicate that the UPS is compensating for a low voltage.
Low Battery
When the UPS is operating on-battery and the energy reserve of the battery runs low, the UPS beeps continuously until
the UPS shuts down from battery exhaustion or returns to on-line operation.
Cold Start
When the UPS is off and there is no utility power, use the cold start feature to apply power to the loads from the UPS’s
battery.
Note:
Cold start is not a normal condition.
•= Press and hold the on/test button until the UPS beeps.
•=Release the on/test button during the beep and the loads are powered within four seconds.
Note:
The UPS starts a self-test as a part of this procedure. The self-test does not affect the voltage display. The utility
voltage bar graph has a margin of error of ±
±±
± 4%.
