ABB INPCT01传输模块中文资料：
ABB INPCT01传输模块如果使用同一直流输入电源为Series 90-30 PLC系统中的两个或多个电源供电，请确保每个机架的连接极性相同（顶部端子+和第二端子-）。不要跨越正极（+）和负极（-）线。由此产生的电位差可能会伤害人员或损坏设备。ABB INPCT01此外，如本章前面所述，每个基板必须连接到公共系统接地。基本安装程序说明：90-30系列PLC必须安装在保护外壳中。外壳应能够适当地散热安装在外壳内的所有设备产生的热量。有关散热计算的详细信息，请参阅附录F。应在开始安装程序之前完成系统设计，包括绘制布局图和接线图。本节提供了安装Series 90-30 PLC系统的基本分步方法。ABB INPCT01
英文资料
If the same DC input power source is used to provide power to two or more power supplies in a Series 90-30 PLC System, ensure that connection polarity is identical at each rack (top terminal + and second terminal -). Do not cross the Positive (+) and Negative (-) lines. A resulting difference in potential can injure personnel or cause damage to equipment. Also, each baseplate must be connected to a common system ground, described earlier in this chapter.Basic Installation Procedure Note: Series 90-30 PLCs must be mounted in a protective enclosure. The enclosure should be capable of properly dissipating the heat produced by all of the devices mounted inside it. For details on calculating heat dissipation, refer to Appendix F. The system design, which includes producing the layout and wiring drawings, should be completed before beginning the installation procedure. This section offers a basic step-by-step approach to installing a Series 90-30 PLC system.ABB INPCT01
