Panel Mounting Using the Dimensional Template
Locate holes every 17.5 mm (0.689 in.) to allow for a mix of single-wide and
one-and-a-half-wide modules (e.g. 1769-OA16).
Panel Mounting Procedure Using Modules as a Template
The following procedure allows you to use the assembled modules as a template
for drilling holes in the panel. If you have sophisticated panel mounting equipment,
you can use the dimensional template provided on page 7. Due to module
mounting hole tolerance, it is important to follow these procedures:
1. On a clean work surface, assemble no more than three modules.
2. Using the assembled modules as a template, carefully mark the center of all
module-mounting holes on the panel.
3. Return the assembled modules to the clean work surface, including any
previously mounted modules.
4. Drill and tap the mounting holes for the recommended M4 or #8 screw.
5. Place the modules back on the panel, and check for proper hole alignment.
6. Attach the modules to the panel using the mounting screws.
7. Repeat steps 1 to 6 for any remaining modules.
TIP
If mounting more modules, mount only the last one of
this group and put the others aside. This reduces
remounting time during drilling and tapping of the next
group.
