MX2000 Three-Phase Delta and Wye AC Power Distribution Module LEDs
Figure 43 on page 103 shows the LEDs on the three-phase delta AC PDM faceplate. The three-phase wye
AC PDM has the same LEDs. The LEDs in Table 27 on page 103 indicate the status of the AC PDM. In
addition, a PDM failure triggers the red alarm LED on the craft interface.
