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 Allen-Bradley Industrial Automation Wiring and Grounding Guidelines, publication
1770-4.1, for additional information.
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.
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.
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.
