Connecting the Simple Locking Connectors
Press the tabs on the end of the connector and insert the connector until it
locks in place. The PLC will not operate properly if the connector isn't inserted
completely. To remove the connector, press the tabs and then pull the connec-
tor out.
1. Do not route the I/O Connecting Cables through ducts that contain the I/O
or power wiring.
2. Always turn OFF the power supply to the PLC before connecting Cables.
3. An I/O bus error will occur and the PLC will stop if an I/O Connecting Ca-
ble's connector separates from the Rack. Be sure that the connectors are
secure.
