1769-L31 CompactLogix™ Controller
Panel mounting
Mount the controller to a panel using two screws per module. Use M4 or #8
panhead screws. Mounting screws are required on every module.
The following procedure allows 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 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.
6. Attach the modules to the panel using the mounting screws.
TIP
7. Repeat steps 1 to 6 for any remaining modules.
DIN rail mounting
The controller can be mounted using the following DIN rails:
• 35 x 7.5 mm (EN 50 022 - 35 x 7.5)
• 35 x 15 mm (EN 50 022 - 35 x 15)
Before mounting the controller on a DIN rail, close the DIN rail latches. Press the
DIN rail mounting area of the controller against the DIN rail. The latches will
momentarily open and lock into place.
Publication 1769-IN069A-EN-P - March 2004
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.
