GE进口卡件模块DS3820PSCB具有一个复位按钮、3个保险丝和1个LED。还配有3个9针连接器、多个电容器和测试点。

电路板上的3个保险丝用于保护电路板上所有组件免受过电压情况以及其他不规则电压情况的影响。如果电路中电压过高，保险丝内的元件将熔化。在这种情况下，保险丝所属的电路将停止工作，电源将停止进入电路，所有部件都将受到电压保护。

但是，如果保险丝熔断，维修人员必须确定过电压状况的原因，并且必须更换保险丝。如果您不熟悉驱动器使用的电源，请咨询工程师或其他知识渊博的人员。

有关保险丝的额定值，请参阅电路板附带的书面材料。务必只将保险丝更换为额定值相同的保险丝。另一个额定值保险丝可能会使组件承受电压，使组件暴露在过高的电压下，从而损坏电路板。

一旦您确定过电压问题得到解决，请断开驱动器的电源。然后，断开连接至板的所有电缆，并使用螺丝刀卸下将板连接至机架式机箱的4颗螺钉。检查保险丝并更换熔断的保险丝。

The GE imported card module DS3820PSCB features a reset button, 3 fuses, and 1 LED. It also comes with three 9-pin connectors, multiple capacitors and test points.

The three fuses on the board are used to protect all components on the board from overvoltage conditions and other irregular voltage conditions. If the voltage in the circuit is too high, the components in the fuse will melt. In this case, the circuit to which the fuse belongs will stop working, power will stop entering the circuit, and all components will be protected by voltage.

However, if the fuse blows, the maintenance personnel must determine the cause of the overvoltage condition and the fuse must be replaced. If you are not familiar with the power supply used by the drive, consult an engineer or other knowledgeable person.

For fuses ratings, refer to the written material that came with the circuit board. Be sure to only replace fuses with those with the same rating. Another rated fuse may expose the component to voltage, exposing the component to too much voltage and damaging the circuit board.

Once you are sure that the overvoltage problem has been resolved, disconnect the power to the drive. Then, disconnect all cables to the board and use a screwdriver to remove the four screws that connect the board to the rack mounted case. Check the fuse and replace the blown fuse.
