Is C600 firmware version 24 compatible with firmware version 16 on a MC4 for an Elau Schnieder product?
You'll have to get in touch with the Schneider support team. I have looked everywhere to find an answer for this request, but nothing found. The support team will provide all the necessary details whether the firmware file is compatible with the products above or not.
