Chapter 2 Installation and Wiring
Mount to a Panel
Mount the module to a panel by using two screws per module. Use
M4 or #8 panhead screws. Mounting screws are required on every
module.
Panel Mounting By 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 By Using the 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. 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.
