Chapter 4 Install the CompactLogix 5370 L3 Controller
Mount the Controller on a Panel
Use two M4 or #8 pan head screws to mount the controller. Mounting screws
are required on many modules. Use this procedure to use the assembled
modules as a template to drill holes in the panel.
1. On a clean work surface, assemble no more than three modules.
2. Use the assembled modules as a template and 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. Use the mounting screws to attach the modules to the panel.
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,
grounds the module 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 process reduces remounting time when
you are drilling and tapping the next group of modules.
