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 19 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 19 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 18 shows the LEDs
and Table 1 explains the corresponding options.
