7. Operating Instructions
With the UPS plugged in, press and release the large upper on/test button to supply power to the loads.
Press and release the small, lower off button to turn off power to the loads.
Note: Whenever the UPS is plugged in and utility voltage is present, the charger maintains battery charge.
The on-line LED illuminates when the UPS is supplying utility power to the loads.
Self-test
The UPS performs a self-test automatically when turned on, and every two weeks thereafter (by default). During the self-test, the
UPS briefly operates the loads on-battery. If the UPS passes the self-test, it returns to on-line operation.
If the UPS fails the self-test it immediately returns to on-line operation and lights the replace battery LED.
SmartTrim
The SmartTrim LED comes on to indicate that the UPS is compensating for a high voltage.
SmartBoost
The SmartBoost LED comes on to indicate that the UPS is compensating for a low voltage.
Overload
When the UPS is overloaded (when the connected loads exceed the maximum specified in the “maximum load” section under
Specifications), the overload LED comes on and the UPS emits a sustained tone.
On Battery
During on-battery operation, the on-battery LED illuminates and the UPS sounds an audible alarm consisting of four beeps every
30 seconds.
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.
Battery Charge Bar Graph
The 5-LED display on the right of the front panel shows the present charge of the UPS’s battery as a percentage of the
battery’s capacity.
Load Bar Graph
The 5-LED display on the left of the front panel represents the power drawn from the UPS as a percentage of total
capacity.
Utility Voltage Bar Graph
With the UPS plugged into the normal utility power, press and hold the on/test button to see the utility voltage bar graph
display. After approximately four seconds the 5-LED display on the right of the front panel shows the utility input
voltage.
The display indicates that the voltage is between the displayed value from the list and the next higher value.
Notes:
The UPS starts a self-test as 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%.
Whenever the UPS is plugged in and utility voltage is present, the charger maintains battery charge.
