Operation

Normal Mode

During Normal mode, the µindicator illuminates and the front panel displays the percentage of UPS load capacity being used by the protected equipment (see Figure 12). The UPS monitors and charges the batteries as needed and provides power protection to your equipment.

When all of the bar graph indicators and the indicator are illuminated, power requirements exceed UPS capacity; see page 45 for more information.

Buck and Double Boost Mode

With the Buck and Double Boost feature, the UPS accepts a wide input voltage range (-30%/+20% of nominal) and provides consistent, clean voltage to your equipment. The UPS operates normally from utility power and alerts you of the voltage fluctuations. The µindicator alternates between green and red while in Buck, Single Boost, or Double Boost mode as shown in Figure 13.
