4. Refer to the CS/CJ-series Programmable Controllers Operation Manual (W339) for information on
wiring inside distribution boxes.
Note 1. Cover all metal portions of cables with insulating tape to be sure they do not come into contact with
the metal ducts or boxes.
2. Securely ground all distribution boxes and metal boxes around transceivers. The lower the ground
resistance, the more effective the shields will be.
3. The twisted-pair cable for 10Base-T is not shielded, and the hub is designed for use in OA environ-
ments. In environments subject to noise, we recommend the use of 10Base-5 Ethernet.
