I. Conversion Preparation
Prior to actually beginning the removal of the Modicon 800 I/O hardware, it is vital to prepare for the I/O field wire swing-arm conversion by at minimum
reviewing the following steps:
a) Inventory the 1492 swing-arm conversion mounting hardware on site to ensure the correct components are available, before removing any 800
I/O hardware. Refer to Appendix A 800 I/O Housing to 1756 I/O Chassis Conversion System Selection Process for details.
b) Inventory the 1492 swing-arm conversion modules (e.g. 1492-CM800-LD002) and 1492 cables (e.g. 1492-CABLE003X, 1492-ACABLE003UC,
etc) to interface the conversion module to the 1756 I/O module. Inventory your 1756 I/O modules, power supply and chassis. Ensure the correct
component types and correct number of those components are on site to complete the conversion. Refer to Appendix B Conversion Module
Selection Process for details.
c) Review the application considerations in each conversion module’s Installation manual to ensure the conversion module or its associated 1492
cable is not being misapplied. A wiring diagram which shows the circuit connections from the 800 I/O swing-arm to the 1756 I/O module is also
in the Installation Manual to assist in possible troubleshooting.
d) Review Rockwell Automation Publication 1770-4.x Industrial Automation Wiring and Grounding Guidelines (available at the Publication
Literature Library: http//.www.ab.com/literature). Ensure to follow these guidelines with particular attention to ground when installing the conver-
sion system.
e) Obtain current and correct 800 I/O wiring schematics prior to disassembly. Typically this will not be used but should be available in advance for
reference.
f) Tools required: Flat blade and phillips screwdriver, box or socket wrench set (size dependent on original installation), cable ties.
