PCD231B 3HHE025541R0101工控模块备件
安装、测试
修理此组件时，需要采取静态控制预防措施。如果不遵守ESD控制程序，可能导致部件损坏。如果您不熟悉静电控制程序，请参阅Allen Bradley出版物8000-4.5.2《防止静电损坏》或任何其他适用的ESD保护手册。出版物2364F-5.13 1999年6月RGU™ 隔离板更换3初步步骤更换电源之前，请关闭电源；锁定/挂牌装置；并等待五分钟以使所有电压放电。打开电源结构的托架门。更换隔离板1.使用仪表测试交流线路、直流母线和隔离板上端子的电压。2.戴上ESD腕带并将其连接到PE母线（装置底部的后接地棒）。3.拆卸Lexan™ 与隔离板隔离。4.断开P1的接地连接、J1的反馈连接、J2的带状电缆以及J7的电流传感器连接（如图1所示）。5.断开接线板TB5和TB6。6.逆时针转动六个安装支架，松开电路板并将电路板拉出。7.从每个接线板上拆下负载电阻器。8.将隔离板放在防静电袋中！
拆下电压源
注意：如果存在任何电压，请拆下电压源。继续下一步前，再次检查电压。出版物2364F-5.13 1999年6月4日RGU™ 隔离板更换图1 RGU隔离板表A：负载电阻器套件 LQVWDODWLRQLQVWUXFWLRQV和2167$1772548（驱动系统285 460 286 3 50/60 276 848 326-DC.9$3+92/76$+）电流电压系列代码位于主控制板附近的典型RGU铭牌例如，此铭牌显示电流代码L和电压代码C。合适的套件为2364-SDP06A。由于铭牌显示这是一个a系列装置，TB2不需要电阻器。a系列B系列1999年PN 192666取代出版物2364F-5.13 1999年3月版权所有1999年国际公司
Installation and testing
Static control precautions are required when repairing this component. Failure to follow ESD control procedures may result in component damage. If you are unfamiliar with static control procedures, refer to Allen Bradley publication 8000-4.5.2, "Preventing Electrostatic Damage," or any other applicable ESD protection manual. Publication 2364F-5.13 June 1999 RGU ™ Preliminary steps for replacing the isolation board 3 Turn off the power before replacing the power supply; Lock out/tag out device; Wait five minutes to discharge all voltages. Open the bay door of the power structure. Replace the isolation board 1. Use the instrument to test the voltage of AC lines, DC buses and terminals on the isolation board. 2. Wear the ESD wrist strap and connect it to the PE bus (the rear ground bar at the bottom of the unit). 3. Remove Lexan ™ Isolate from the isolation plate. 4. Disconnect P1's grounding connection, J1's feedback connection, J2's ribbon cable and J7's current sensor connection (as shown in Figure 1). 5. Disconnect terminal blocks TB5 and TB6. 6. Rotate the six mounting brackets anticlockwise, release the circuit board and pull it out. 7. Remove the load resistor from each terminal block. 8. Put the isolation plate in the anti-static bag!
Remove the voltage source
NOTE: If any voltage is present, remove the voltage source. Check the voltage again before proceeding to the next step.

For example, this nameplate shows current code L and voltage code C. The appropriate kit is 2364-SDP06A. Since the nameplate shows that this is a series a device, TB2 does not need a resistor.
