2. Connecting the shields only at the Ethernet switch side
Connect the shields to the connector hoods only at the Ethernet switch side.
• For an NX-series CPU Unit, a clamp core must be attached to the end of the cable at the
EtherNet/IP port side. For a recommended clamp core and attachment methods, refer to
Recommended Clamp Core and Attachment Method on page 2-10.
To comply with EMC standards, it is mandatory that a clamp core be attached when con-
necting the shield to the connector hood only at the Ethernet switch side.
• For an NJ-series CPU Unit, it is not necessary to attach a clamp core.
