Panel Mount
Mount the module to a panel using two screws per module. Use M4 or #8
panhead screws. Mounting screws are required on every module.
Panel Mounting Using the Dimensional Template
Panel Mounting Procedure Using Modules as a Template
This procedure lets you 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. Due to module mounting hole
tolerance, it is important to follow these procedures.
1. Assemble no more than three modules on a clean work surface.
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…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.

Spacing for single-wide modules 35 mm (1.378 in.).
Overall hole spacing tolerance:
±0.4 mm (0.016 in.).
Spacing for one-and-a-half-wide modules 52.5 mm (2.067 in.).
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).
