The GE CPU Board DS3800HMPG1G1D is designed for quick installation in the drive. The board features a modular connector on 1 end and retention levers on the other end. The GE CPU Board DS3800HMPG1G1D also is populated with 2 red indicator LEDs and 1 amber LED which are visible from the front of the board. The board also is populated with a microprocessor, erasable programmable read-only memory (EPROM) modules, and a 34-pin connector.
Before you begin any maintenance or service on the drive, including replacing the GE CPU Board DS3800HMPG1G1D, there are some preliminary considerations to keep in mind. The drive is a high-voltage device that can cause serious injury if the servicer is shocked by the electric current. You must also understand the danger caused by the powerful motor and moving parts. They can also cause injury. Visually inspect the area and note any moisture or water on the floor. Because water is a conductor, it is a hazard to have water on the floor while working with high-voltage current. Use towels or another method to dry the floor completely. If the floor is moist from condensation, consider installing a dehumidifier or other device to dry the air. If any devices are attached to 2-wire extension cords, remove the extension cords from the area around drive. They are a shock hazard and are not safe to have in the area.
Locate and inspect all the emergency shutdown devices associated with the drive. Make sure they are functional and are easy to find in an emergency.
