4.2.1.3 Graphical front panel
The graphical front panel consists of a USB port, LED panel, color screen display, user-programmable pushbuttons, and
navigation keys. The screen is used to read data, such as metering actual values, alarms, self-test messages, and event
records, and for viewing single-line diagrams. Settings can be changed on the front panel, except for the graphical front
panel itself and for IEC 61850. The USB port connects to a computer with the EnerVista software and can be used to
upgrade the relay and to transfer files and settings. The USB port is the square type B.
