Chapter 1 Compact I/O ASCII Module
Panel Mount Procedure with Modules as a Template
The following procedure lets you 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.
Mark the center of all module-mounting holes on the panel by using the
assembled modules as a template.
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.
If mounting more modules, mount the last one of this group only and put
the others aside. This reduces remounting time during drilling and tapping
of the next group.
7.
Repeat steps 1…6 for any remaining modules.
DIN Rail Mount
The module can be mounted on these DIN rails:
• 35 x 7.5 mm (EN 50022 - 35 x 7.5)
• 35 x 15 mm (EN 50022 - 35 x 15)
Before mounting the module on a DIN rail, close the DIN rail latches. Press the
DIN rail mounting area of the module against the DIN rail. The latches
momentarily open and lock into place.
IMPORTANT
When mounting the CompactLogix system, either use screws to panel mount
the system
or use DIN rail. Do not use both. Use of both mounting methods
can cause hardware damage and cause the system to fail.
