Rockwell Automation 1492 1771-to-1756 I/O Swing-arm Conversion System - Manual (Page 6)

II. Conversion Steps
5) Install the 1771 Swing-arm into the Conversion Modules
a) Locate the 1492 conversion module that mates to the 1771 I/O swing-arm and conversion base-plate slot location. Review both conversion
module and swing-arm labels to ensure a correct match. Refer to Appendix B or C for additional component compatibility details.
b) Refer to Figure 5a and 5b, With the proper swing-arm selected for the conversion module (review labels), guide and press the lower part of the
1771 swing-arm into the horizontal bar located in the lower part of the conversion module. NOTE: this allows the swing-arm to pivot like it did in
the 1771 chassis. Pivot the swing-arm terminals to mate with the conversion module terminal until the locking tab at the top of the swing-arm
snaps into place on the conversion module.

Before inserting the 1771 I/O swing-arm terminal block into the conversion module it is recommended that the terminal block contacts be
carefully inspected and cleaned if necessary to ensure a good electrical connection with the conversion module. A mild abrasive (e.g. pencil
eraser) is recommended. Do not use a solvent. NOTICE
