Chapter 2 Installation and Wiring
Mount to a Panel
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
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).
Panel Mounting Using the Modules as a Template
This procedure lets 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. 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.
