The GE Power Excitation Board DS3800NEPB1C1B can only operate when connected to the GE Mark IV PC Board. The board must be connected to a motor excitation board.
Depending on the work the board performs, the board is build with one of two heat sinks. If the application is reversing one heat sink model is installed on the board. If the application is non-reversing, a different heat sink is installed on the board. The heat sink is intended to draw heat from one or more components in order to prevent the board from overheating.
The DS3800NEPB1C1B board is installed in the power conversion module and there are considerations you must take into account when you install the board. Make sure the board is installed in the module according to specifications. That is, make sure the board has space around it to allow the heat generated by the board to exit the module. All the components in the module generate heat and an overheat condition might cause the module to shutdown or operate unreliably.
If the heat cannot be kept at a room temperature or within the specified operating temperature, you might have to install fans or forced air ventilation. This might include air ventilation hoods or an air cooling system.
Do not operate the module in a space that is excessively dusty or dirty. Another best practice is to make sure all cables are routed to avoid interference. This applies to keeping signal cables at a distance from 3-phase power cables.
