Product Description

The GE Field Exciter Board DS2020FECNEX015A features 7 jumpers and 2 terminal blocks with 3 terminals on each. The jumpers are identified as JP1 through JP7. The GE Line Protection Board DS2020FECNEX015A also contains test points. The board is installed on standoffs on another component of the drive. The signal wires that connect to the board originate on the component to which it is attached.

The board also is populated with capacitors that pose a safety risk if you do not take the necessary precautions before handling the board. Capacitors are used on many boards and serve the purpose of storing and releasing electric energy during normal processing of the board. However, if you touch the board when the current is removed from the board but the capacitor are still storing electric energy, a serious shock hazard can exist which can lead the an electric burn or other injury. However, after 30 seconds of being removed from power the capacitors on the board lose the electric energy they have stored and the boards are safe to touch. With that in mind, it is best practice to wait 30 seconds after you remove power from any board before you touch it.

Another important risk from electric shock is caused by the fact that the drive often is connected to more than one source of power. If that is the case the servicer might assume that all power is removed and attempt to handle boards or other devices in the drive. Serious injury might occur so always test the drive for power.
