II. Conversion Steps
Figure 4b
Figure 4a
b) Insert the Conversion Module into the Base-plate:
Refer to Figure 4b, Notice the opening at the bottom of the base-plate and the plastic extension at the bottom of the conversion module. These
two parts mate together and lock the bottom of the module to the base-plate. To get them to lock, (Refer to Figure 4c) place the module at
approximately a 30 degree angle (lower part to upper part) to the back of the base-plate. With the aid of the lower two horizontal tabs/guides
(Refer to Figure 4d), guide the plastic extension into the opening at the bottom of the base-plate. Once this is done, the module will insert
between the remaining horizontal tabs and will snap into place at the upper base-plate opening using the plastic spring finger at the top of the
module (refer to Figure 4e) NOTE: The plastic spring is also used to remove the conversion module from the base-plate.
c) Repeat steps 4a and 4b until all of the required conversion modules are installed into the base-plate.
4) Install the 1771 I/O Conversion Modules into the Base-plate
a) Match the Conversion Module with the 1771 I/O Swing-arm:
Begin conversion at the left most slot of the base-plate and continue inserting modules left-to-right. Find the 1492 conversion module that mates
to the 1771 swing-arm (I/O module) that was previously inserted in that slot of the 1771 I/O chassis. NOTE: Closely review the 1771 I/O module
Catalog Number and slot location information you placed on the swing-arm label in steps 1a and 1b. The nameplate label on the conversion
module (refer to Figure 4a for an example) indicates which 1771 I/O module it is compatible with. Compare that information to the label on the
swing-arm to ensure there is a functional match.
There is a label on the 1492 conversion module to indicate which 1771 to 1756 I/O module it is capable to convert. Also refer to Appendix B
for a conversion list.
