Replace Battery, Battery Charge Bar Graph

Replace Battery

If the battery fails a self-test, the UPS emits short beeps for one minute and the replace battery LED illuminates. The UPS repeats the alarm every five hours. Perform the self-test procedure to confirm replace battery conditions. The alarm stops when the battery passes the self-test.

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. When all five LEDs light, the battery is fully charged. The top LED goes out whenever the battery is not 100% charged. When the lowest LED is flashing, the battery can supply less than two minutes of run time for the load.

Shutdown Mode

In shutdown mode the UPS stops supplying power to the load, waiting for the return of utility power. If there is no utility power present, external devices (e.g., servers) connected to the computer interface or the accessory slot can command the UPS to shut down. This is normally done to preserve battery capacity after the graceful shutdown of protected servers. The UPS will scroll the front panel indicators sequentially in shutdown mode.

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. 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.

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 beeps and the loads are powered within 4 seconds.

	84

The display indicates that the voltage is between the displayed value from the list and the next higher value. For example, with three LEDs lit, the input voltage is between 101 and 109 VAC.

If no LEDs come on and the UPS is plugged into a working AC power outlet, the line voltage is extremely low.

If all five LEDs come on, the line voltage is extremely high and should be checked by an electrician

Note: 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%.
