Panel Mounting Procedure Using Modules as a Template
The following procedure allows you to use the assembled adapter and modules as a template for
drilling holes in the panel. If you have sophisticated panel mounting equipment, you can use the
dimensional template provided on page
11 .
Due to the 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.
7. Repeat steps 1 through 6 for any remaining modules.
DIN Rail Mounting
The adapter can be mounted using the following DIN rails:
• 35 x 7.5mm (EN50022 - 35 x 7.5)
• 35 x 15mm (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 will momentarily open and lock
into place.
TIP 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.
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, for example, aluminum and plastic, that can corrode, oxidize, or are poor
conductors, can result in improper or intermittent grounding.
