由于通风问题，请勿垂直或水平安装。底座安装表面是否有任何突出、凹陷或变形

单元，对印刷电路板施加过大的力并导致问题，

因此，安装在一个平面上。

（4） 避免与任何振动源共用同一面板，例如大型

电磁接触器或无熔断器断路器，并将其安装到单独的面板或

远离这些设备。

（5） 必要时提供接线管道。

但是，当PLC顶部或底部的间隙小于

如图8.1和图8.2所示，请注意以下几点：

（a） 在PLC上安装管道时，管道高度必须为50mm

（1.97英寸）或更小，以允许足够的气流。

将PLC放置在正确的位置，以便用户可以按下

模块顶部。

如果无法按下挂钩，则无法更换模块。

（b） 在PLC下方放置管道时，应考虑使用光纤

电缆或同轴电缆以及电缆的最小弯曲半径

Do not install vertically or horizontally, because of concerns with ventilation.If there are any protrusions, dents or distortion on the installation surface of the base

unit, an excessive force is applied to the printed-circuit board and causes problems,

so, install to a flat surface.

(4) Avoid sharing the same panel with any source of vibration such as a large-sized

electromagnetic contactor or no-fuse breaker, and install it to a separate panel or

away from such devices.

(5) Provide wiring ducts as necessary.

However, when the clearance from the top or bottom of the PLC is less than

described in Fig. 8.1 and Fig. 8.2, pay attention to the following:

(a) When installing a duct over the PLC, the height of the duct must be 50mm

(1.97inch) or less to allow sufficient air flow.

Place the PLC in the proper position so that the user can press the hook on the

top of the module.

Module replacement is not possible if the hook cannot be pressed.

(b) When placing a duct under the PLC, take into account the use of optical fiber

cables or coaxial cables as well as the minimum bending radius of the cables
