II. Conversion Steps
b) Locate the 1492 conversion module that mates to the 800 I/O terminal block and conversion base-plate slot location. Review both conversion
module and terminal block labels to ensure a correct match. Refer to Appendix B for additional details.
c) Identify the terminal block insertion guides on both ends of the 800 I/O terminal block and the insertion guides of the conversion module. Refer
to Figures 4c and 4d.
d) Refer to Figures 4e and 4f. Using the terminal block guides, carefully slide the 800 I/O terminal block into the mating conversion module slots.
Continue sliding the terminal block forward so its field connection (V-shaped slot) slides into the module’s circuit board tabs and press the two
components together to ensure the mating terminals are fully engaged. When fully engaged the screw hole on the 800 I/O terminal will align
with the screw hole on the conversion module (refer to Figure 4g).
Before inserting the 800 I/O 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.
