Description

The GE Turbine Control Board DS3800DPSS features 6 fuses and 1 34-pin connector. The GE Turbine Control Board DS3800DPSS also is populated with 7 terminals with retention screws, multiple capacitors, and 1 jumper.

The capacitors on the GE Turbine Control Board DS3800DPSS present a safety concern when you plan to remove the board and replace it with another. During normal processing that occurs when the drive is in operation, the capacitors store current and when commanded, release the high voltage to cause a particular result. During normal operation the capacitors store and release current without any safety concerns. However, during the procedure to replace the drive, the power is removed so that the technician can touch the board without a concern for the presence of electrical current. You must be aware that the capacitors might still retain dangerous current. The capacitors lose the stored current after only 30 seconds once power is removed. For this reason, once power is removed from the drive, wait 30 seconds before starting the procedure to replace the board.

Another consideration when you replace the board are the components attached to the terminals. The terminals enable the technician to add components to the board. The qualified technician can add a resistor, capacitor, or other component by inserting the lead wires under the retention screws. When the board is replaced, you can remove the components from the defective board and install them on the replacement board. Wear a wrist strap when you remove and install the components. Also, make sure you install the components on the same terminals.
