Field Installation Guidelines
Install the 1768-CNB module in the designated CompactLogix chassis slot and verify backplane compatibility before applying system power.
Connect ControlNet network cables according to the approved network topology. Maintain proper cable routing separation from high-voltage power wiring to reduce electromagnetic interference.
Verify network addressing, node configuration, and controller communication parameters before commissioning. Apply correct shield grounding practices for ControlNet cabling according to the installation standard used by the control system.
Ensure the installation environment remains within the specified operating temperature range and protect the module from excessive vibration, conductive contamination, and unauthorized physical access.
