Mount Module to Panel 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 (for example, the 1769-OA16 module).
Mount Module to Panel Procedure Using Modules as a Template
This procedure lets you use the assembled modules as a template for drilling holes
in the panel. Due to module-mounting hole tolerance, it is important to follow this
procedure.
Refer to Mount Module to Panel Using the Dimensional Template on page 9 if you
have sophisticated panel-mounting equipment.
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 screws.
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 the remounting time during drilling and tapping of
the next group.
Spacing for single-wide modules 35mm (1.378 in.)
Spacing for one-and-a half-wide modules 52.5mm (2.067 in.)
