The DS200DPCBG GE IOS + Power Connect Board features two wire terminal blocks to attach a maximum of 6 signal wire and is populated with 1 fuse and one toggle switch. When replacing this board it is necessary to connect the signal wires to the same connectors on the terminal blocks. Take note that the terminal blocks have identifiers for the individual connectors. Diagram or label the terminal blocks to provide yourself a plan showing the identifiers and also what terminals have wires attached to them. Tape on the signal wires the identifier they are attached to on the terminal block. Consult with an electrician who is familiar with the installation of the drive to understand how the drive is powered. The drive receives power from a Power Supply and the best practice is to remove the fuses from the Power Supply to remove power from the drive. Keep the fuses in a safe place but removed from the Power Supply so that someone doesn?t replace the fuses while the servicer is working on the replacement procedure. Use a screwdriver to loosen the screw that retains the wire in the terminal. However, make sure the screwdriver doesn?t touch any other components in the drive. The screwdriver might scratch a board or damage components or cause components to fall off the board. This PC board assembly has been discontinued by the OEM.
