The extender carries the bus relationship beyond the basic unit, so connector identity, station topology, cable route and module order must be retained together. It is not a general-purpose communications converter.
Important Notice: Verify CI610 3BHT300003R1 and the complete station topology before removal. Do not substitute a similarly named controller interface or change the bus order during service.
The technical reference organizes exact characteristics and engineering boundaries. The installation guide focuses on controlled preparation, restoration, commissioning and handover.
