Connecting to the Network
The following standards and specifications apply to the connectors for the Ethernet twisted-pair cable.
•
Electrical specifications: Conforming to IEEE 802.3 standards.
•
Connector structure: RJ45 8-pin Modular Connector (conforming to ISO 8877)
Precautions for Correct Use
Precautions for Correct Use
•
Turn OFF the power supply to the Controller before you connect or disconnect twisted-pair
cable.
•
Allow more than enough space for the bending radius of the twisted-pair cable. The space that
is required depends on the communications cable and connector that you use. Contact the
manufacturer or sales agent.
1
Lay the twisted-pair cable.
2
Connect the cable to the Ethernet switch.
3
Connect the twisted-pair cable to the connector on the EtherNet/IP Unit. Be sure to press the connec-
