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 -30% of 120V or 230V nominal

Higher than +20% and lower than -30% of 120V or 230V nominal

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.
