Generac 0H6680D Nexus Control Panel. This controller is a direct replacement for existing Nexus 0H6680D part number controllers. If you have a Nexus controller with the part numbers 0H6680A or 0H6680B, this controller is not a direct fit. You will need the 0H6680DSRV replacement kit, which includes an adapter harness and instructions for mounting the adapter harness.
This is also NOT a replacement for 0H6680T or 0H6680E which are different controllers and still available.
Controller will not need to be activated as the original was with an activation code.
Panels should be installed by a qualified technician who can check output voltage and frequency to ensure proper calibration.
Generac replacement parts will also usually fit the following Generac branded generators: Honeywell, Guardian, Siemens, Carrier, Watchdog, Centurion, Eaton & Bryant.
