2.5 DRED AND FAULT IN THE GROUND CONNECTION
2.5.1 DRED CONNECTION
The DRED connection is only used in Australia and New Zealand. DRED equipment is not provided
by GoodWe. GoodWe series ET changers comply with IEC 62109-213.9. The fault indicator
("FAULT") is located on the changer's taskbar and lights up in red in the event of a malfunction.
The changer then sends the customer information about the malfunction.
The wiring diagram for the DRED device is shown below:

Note: The DRED device should be connected via the "DRED port" as shown in
the picture.
