DGC-2020HD Typical Applications
Figure 3-2. 3-Phase Wye Bus Voltage Sensing Connections
Figure 3-3 illustrates typical three-phase delta connections for all DGC-2020HD bus voltage sensing
connections: Generator, Bus 1, and Bus 2. Use the terminal numbers listed below for connecting the
desired bus type. Refer to the Terminals and Connectors chapter for rear panel terminal numbering.
For Generator voltage sensing, VA = 86, VB = 88, and VC = 90.
For Bus 1 voltage sensing, VA = 93, VB = 95, and VC = 97.
For Bus 2 voltage sensing, VA = 100, VB = 101, and VC = 103.
Figure 3-3. 3-Phase Delta Connections
Figure 3-4 illustrates typical single-phase A-B connections for all DGC-2020HD bus voltage sensing
connections: Generator, Bus 1, and Bus 2. Use the terminal numbers listed below for connecting the
desired bus type. Refer to the Terminals and Connectors chapter for rear panel terminal numbering.
For Generator voltage sensing, VA = 86, VB = 88, and VN = 91.
For Bus 1 voltage sensing, VA = 93, VB = 95, VN = 98.
For Bus 2 voltage sensing, VA = 100, VB = 101, VN = 104.
