5.2 Wall mounting

壁挂安装

Wall mounting is an alternative to DIN rail mounting of the AC 900F controller. The description below generally also applies for installation on a mounting panel inside a cabinet.

壁挂安装是AC 900F DIN导轨安装的替代方式。下面的描述通常也适用于安装在机柜内的安装面板上.

5.2.1 PM CPU module

PM CPU模板

The CPU module features four bores for screws on the rear side of the housing (see arrows).

CPU 模块具有四个螺丝孔（参见图中箭头）。

 

Suitable dowels and screws (e.g. 4 x 50 mm) must be selected depending on the wall material at the place of installation。

必须根据安装地点的墙面材料选择合适的钉子和螺丝（例如 4 x 50 mm）

The enclosed mounting set (red parts) is intended for both upper screws. Both plastic tubes are designed to bridge the gap between the plastic housing and the wall. Insert the nose of these tubes into the bore provided in the plastic housing

封闭式安装装置（红色部件）用于两个上螺钉。双塑料管旨在弥合塑料外壳和墙。将这些管子的鼻子插入塑料外壳提供的孔中

5.2.2 TU terminal blocks

TU终端块

       When using a direct I/O, the corresponding number of I/O terminal blocks must be connected on the right side of the CPU module using the previously attached accessory part. The TA526 accessory part for wall mounting prevents any deformation of the terminal block during fixing to the wall. It is recommended to mount the terminal blocks in small groups of up to three units. After having marked the correct position and drilled the bores, the terminal blocks can be fixed by means of screws. Use two M4 screws per terminal block for this purpose. The screws must be inserted at the terminal block front.

      使用直接 I/O 时，必须使用以前附加的配件部分连接 CPU 模块右侧相应数量的 I/O 终端块。用于墙壁安装的 TA526 配件可防止在固定墙壁时终端块的任何变形。建议将终端块安装成最多三个单元的小组。在标记了正确的位置并钻孔后，终端块可以通过螺丝固定。

螺丝必须插入终端块前部。
