安裝I/O擴展電纜
可使用21”（54.61 cm）輸入/輸出擴展電纜（IC670CBL002）代替標準電纜
底座之間需要更多空間的底座間電纜。TOSHIBA 2N3A8130-A只能使用一根輸入/輸出擴展電纜
每個站點使用。必須使用提供的較短接頭進行其余連接帶底座。

輸入/輸出擴展電纜可以將輸入/輸出基座與總線接口單元基座或其他基座連接
輸入/輸出基座。安裝電纜時，必須確保從一個基座到另一個基座的數據流方向一致
下一個。也就是說，電纜將連接一個基座的“底部”和下一個基座的“頂部”
如果底座的方向相同（使用短電纜時必須如此）。

必須移除保護標簽的角，以便接觸接線盒電纜
連接器。接頭上有鍵，以確保正確安裝。
為獲得適當的抗擾度保護，請將兩根排流線連接到機箱接地。這是可以做到的
通過使用DIN軌夾，或在每條排流線上放置環形端子并連接每個環
用螺釘和星形墊圈將端子連接到安裝板上。
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.
