Ground the Wiring
This product is intended to be mounted to a well-grounded mounting surface
such as a metal panel. Additional grounding connections from the controller’s
mounting tabs or DIN rail (if used) are not required unless the mounting
surface cannot be grounded.
Refer to the Allen-Bradley publication 1770-4.1, Industrial Automation
Wiring and Grounding Guidelines, for additional information.
TIP Compact I/O expansion cables have the same dimensions as the end caps.
Expansion cables can be used on either the right or left end. A 1769-ECR
right end cap or 1769-ECL left end cap terminates the end of the
communication bus.
ATTENTION This product is grounded through the DIN rail to chassis ground. Use zinc
plated yellow-chromate steel DIN rail to assure proper grounding. The use of
other DIN rail materials (such as aluminum or plastic) that can corrode, oxidize,
or are poor conductors, can result in improper or intermittent grounding.
Secure DIN rail to mounting surface approximately every 200 mm (7.8 in.) and
use end-anchors appropriately.

Mount the Panel
Mount the controller to a panel by using two screws per module. Use M4 or
#8 panhead screws. Mounting screws are required on every module.
This procedure lets you use the assembled modules as a template for drilling
holes in the panel.
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 by using the mounting screws.
7. Repeat steps 1...6 for any remaining modules.
IMPORTANT Due to module mounting hole tolerance, it is important to follow these
procedures.
TIP The grounding plate, that is, where you install the mounting screws,
enables the module to be grounded when it is panel-mounted.
TIP If you are mounting more modules, mount only the last one of this group and
put the others aside. This reduces remounting time when you are drilling
and tapping the next group of modules.
