affected by a failed test. Recharge the battery for 24 hours and perform another self-test. If it fails,
the battery must be replaced. See Replacing the Battery, page 16, for details.

Automatic Self-Test
The UPS performs a self-test automatically when turned on, and every two weeks thereafter (by
default). Automatic self-test eases maintenance requirements by eliminating the need for periodic
manual self-tests.

Utility Power
During normal operation, the UPS monitors the utility power and delivers power to the connected
equipment. If your system is experiencing excessive periods of high or low voltage, have a
certified electrician check your facility for electrical problems. If the problem continues, contact
the utility company for further assistance.

This UPS has a diagnostic feature that displays the utility voltage. With the UPS plugged into the
normal utility power, press and hold the on button to see the utility voltage bar graph display.
After a few seconds the 5-LED display on the right of the front panel shows the utility input
voltage. Refer to the figure to the left for the voltage reading (values are not listed on the UPS).

After a few seconds the 5-LED display on the right of the front panel shows the utility input
voltage. Refer to the figure to the left for the voltage reading (values are not listed on the UPS).
The display indicates that the voltage is between the highest LED lit and the next higher value.
For example, with three LEDs lit, the input voltage is between 91 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.

Voltage Trim
This LED comes on to indicate that the UPS is compensating for a high utility voltage.
Voltage Boost
This LED comes on to indicate that the UPS is compensating for a low utility voltage.
