Installation Notes
Install the module in any I/O slot of the compatible 1771 chassis, excluding the extreme left slot which is reserved for processors or adapters [citation:4]. Connect field wiring using the 1771-WH wiring arm, which allows module replacement without disconnecting field wires. Remove power from the backplane and wiring arm before installing or removing the module [citation:4]. Key the backplane connector according to the module requirements before insertion. For conversion to newer platforms, Rockwell provides field wire conversion modules such as 1492-CM1771-LD001 for migration to 1756-IA16 [citation:15].
