Field Installation Guidelines
Install the 1756-L61/B processor module into a compatible ControlLogix chassis slot and verify full engagement with the chassis backplane connector before system power application.
Connect the RS-232 serial interface using appropriate shielded communication wiring. Maintain separation between communication cables and high-current power conductors to reduce electrical interference.
For redundant controller installations, verify matching controller configurations, firmware compatibility, and redundancy module installation requirements before commissioning. CompactFlash memory devices should be installed or removed according to standard controller maintenance procedures.
