About the 0-56949-50
The 0-56949-50 model is listed by Reliance Electric as a power PCB to be used with GV3000 drives. This model is considered a replacement board for drives that operate on 25-60 HP. This model works in conjunction with several components of the GV3000 drives; some of the components that the 0-56949-50 will work with are the fan, which is part number 69739-48A, a membrane switch keypad/top bracket, which is part number 805548-1R, an internal fan assembly, which is part number 615196-2R, and more. It should be noted that all of these available part numbers are considered replacement parts for the GV3000 drives.
This model will be directly inserted into the GV3000 drives. Caution should be taken when inserting the model into the drive after removing the previous power PCB. The drive will need to be opened to install the 0-56949-50 unit so that the original PCB can be removed. All connectors that are used to hold down the original PCB should be removed carefully to not break them; if the connectors are broken or damaged, it can affect how the PCB is held within the drive and could slow down the installation process.
For more information on how this model will interface and react with the GV3000 drive, refer to the GV3000/SE AC Drive Hardware Reference, Installation, and Troubleshooting Manual D2-3360.
