Location of Communication PCB LED Lights
The communication PCB’s four LED lights can be found in two locations.
• Communication card – The primary location is on the face of the communication
card which resides in the card cage in the right side of the Power Module Assembly.
Refer to Figure 7-6.
• Comm X PCB – The additional set of LED lights are on the Comm X PCB located
in the Data Monitoring Section in the front upper right of the inverter. These four
lights are surface mount LEDs located near the Ethernet connector. Refer to Figure
