Panel Mounting Procedure Using Modules as a Template
The following procedure allows you to use the assembled 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 the previous page. 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. 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.
NOTE 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.
7. Repeat steps 1 to 6 for any remaining modules.
DIN Rail Mounting
The module can be mounted using the following DIN rails:
· 35 x 7.5 mm (EN 50 022 - 35 x 7.5), or
· 35 x 15 mm (EN 50 022 - 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.
