Panel Mounting Procedure Using Module as a Template
The following procedure enables you to use the assembled modules as a
template for drilling holes in the panel. Due to module mounting hole
tolerance, it is important to follow these steps:
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.
