Configuring Voltage and Frequency
The UPS automatically attempts to match the voltage and frequency to the existing utility. If the UPS is unsuccessful or if you want to bypass the automatic configuration, the voltage and frequency can be selected manually.
Automatic Configuration Mode
Automatic configuration is performed only during the initial UPS startup or during a bypass startup. The UPS attempts to match voltage and frequency to the existing utility.
When the input voltage and frequency have been determined, the UPS beeps twice and cycles through all the LEDs. One of the LEDs remains blinking. The blinking LED shows the configuration which has been automatically selected (see the configuration table on page 37).

Verify that the LED corresponds with the correct input voltage.
The UPS is
NOTE When the LED indicating the automatic selection blinks for 10 seconds during startup, you can press the RESET pushbutton on the LED panel to interrupt the UPS startup and switch to Manual Configuration Mode (see Steps 2 through 4 on page 37).
:If the automatic selection is the same as the factory configuration, the LED blinks for only 10 seconds. The LEDs cycle again and the UPS starts up.
:If the automatic selection differs from the factory configuration, the UPS does not start and the corresponding LED blinks.
To accept the automatic selection, press the RESET pushbutton momentarily to store this selection in the UPS. The UPS beeps twice and cycles through the LEDs. The LED indicating the automatic selection blinks for 10 seconds and the UPS continues to start up.
To cancel the automatic startup, press and hold the RESET pushbutton for longer than three seconds. The UPS beeps twice and goes to Manual Configuration Mode (see Steps 2 through 4 on page 37).
