安装I/O扩展电缆
可使用21”（54.61 cm）输入/输出扩展电缆（IC670CBL002）代替标准电缆
底座之间需要更多空间的底座间电缆。TOSHIBA 2N3A8130-A只能使用一根输入/输出扩展电缆
每个站点使用。必须使用提供的较短接头进行其余连接带底座。

输入/输出扩展电缆可以将输入/输出基座与总线接口单元基座或其他基座连接
输入/输出基座。安装电缆时，必须确保从一个基座到另一个基座的数据流方向一致
下一个。也就是说，电缆将连接一个基座的“底部”和下一个基座的“顶部”
如果底座的方向相同（使用短电缆时必须如此）。

必须移除保护标签的角，以便接触接线盒电缆
连接器。接头上有键，以确保正确安装。
为获得适当的抗扰度保护，请将两根排流线连接到机箱接地。这是可以做到的
通过使用DIN轨夹，或在每条排流线上放置环形端子并连接每个环
用螺钉和星形垫圈将端子连接到安装板上。
Installing an I/O Expansion Cable
The 21" (54.61 cm) I/O Expansion Cable (IC670CBL002) can be used in place of the standard
inter-base cable where more space is needed between bases. Only one I/O Expansion Cable can be
used per station. The remaining connections must be made using the shorter connectors supplied
with the bases.

The I/O Expansion Cable can connect an I/O base with the Bus Interface Unit base or with another
I/O base. The cable must be installed so that direction of data flow is consistent from one base to
the next. That is, the cable would connect the “bottom” of one base with the “top” of the next base
if the bases were both oriented the same way (as they must be when using the short cable).

The corners of the protective labels must be removed to permit access to the Terminal Block cable
connectors. The connectors are keyed to assure proper installation.
For proper noise immunity protection, connect both drain wires to chassis ground. This can be done
by using a DIN rail clamp, or by placing a ring terminal on each drain wire and attaching each ring
terminal to the mounting plate with a screw and star washer.
