Controls and Indicators

3.2Indicators

The operation and display panel has seven indicators (see Figure 18). The indicators can be divided into two groups according to the applications: level indicators and UPS status indicators.

3.2.1Level Indicators Battery Level Indicators

The battery level indicator is composed of five sets of LED bars that illuminate and flash to indicate the battery capacity level. The Liebert® GXT3battery capacity level is shown in 20% increments (±5%). The battery level indicators will illuminate as shown in Figure 19.
