Mount to Module with Screws by Using the Modules as a Template
The following procedure lets you 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
70 .
Due to the module-mounting hole tolerance, it is important to follow this
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 all
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 with the mounting screws.
7. Repeat steps 1 through 6 for any remaining modules.
Mount on a DIN Rail
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)
Follow these steps to mount the module.
1. Verify that the DIN rail latches are closed.
2. Press the DIN rail mounting area of the module against the DIN rail.
The latches momentarily open, then 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.
