Why Change Factory Defaults?
Nominal Input Voltage
When the utility power consistently fluctuates, the UPS repeatedly corrects the input voltage by switching to battery power when the nominal input range is:
:Higher than +20% of 120V or 230V nominal
:Lower than
:Higher than +20% and lower than
You can configure the UPS to more closely match the nominal input voltage by selecting a different input voltage or extending the input voltage range. See Table 1 on page 17 for a list of available options.
Other Settings
You can change the UPS default configurations for alarms and shutdown parameters, including: timing for the low battery alarm, the time delay for an unconditional shutdown, alarms for loss of utility power or site fault, and controlling loads that use less than 5% of the current when the UPS is on battery. See Table 1 on page 17 for a list of available options.
Configuration Mode
When the UPS is in Configuration mode, the LEDs represent the
configuration options. The control buttons (On button and 
button) are used to modify the UPS configuration. Figure 14 shows the LEDs and Table 1 explains the corresponding options.
