DS3800NEPB

GE's DS3800NEPB is a power excitation board from the Mark IV series. Power amplifiers, a field current feedback signal, an armature current feedback signal, a calibration circuit, high voltage resistor bridges, and a heatsink assembly are all included on the board. The board is inserted in the power conversion module, and the installer is exposed to deadly quantities of electrical energy if the module is turned on.

To provide a safe working environment, turn off the module and all other equipment, then turn off the power source.

• A manufacturing facility normally features three-phase power sources that provide enough power to run all of the gadgets. An engineering drawing detailing the 3-phase power wiring utilized at the site is normally available for your use. Refer to it to find the power source for the drive. To turn off the power to the drive, remove the fuses from the source.
• Examine the board's delivery box for damage and lay it on a clean, flat surface. When you open the box, you'll discover that the board is protected by a protective wrapper. Keep it in the wrapper to avoid static electricity.
• Static can harm the components on the board, resulting in a damaged board. Remove the board from the static protective bag as soon as possible before handling or installing it. If necessary, connect the DS3800NEPB board to other boards before installing it in the power converter module.
