📘 Product Instructions
- Isolation: Ensure that all primary power feeds to the Series C chassis, node backplane, and fieldbus power supplies are completely switched off and locked out before installation or extraction.
- Mounting: Carefully align and secure the CC-PFB401 module onto its designated Series C carrier/IOTA backplane slot, ensuring connection pins and FTE network ports seat smoothly without binding.
- Wiring Termination: Connect fieldbus trunk and spur cables to the appropriate detachable terminal blocks, ensuring proper shielding, impedance matching, and termination resistor placement per Fieldbus standards.
- Verification: Check configuration parameters, node addresses, macrocycle timings, and redundancy settings within the Experion Control Builder engineering station prior to startup.
- Initialization: Restore power to the control rack and observe front-panel diagnostic indicators to verify successful hardware boot, Fault Tolerant Ethernet (FTE) sync, and active communication across all H1 links.
