Practical tip
The following procedure allows you to use the mounted modules as a template for drilling holes
in the panel. Due to module mounting hole tolerance, it is important to follow these procedures:

On a clean work surface, mount no more than 3 modules (e.g. one terminal base and two
terminal units).
Using the mounted modules as a template, carefully mark the center of all module-
mounting holes on the panel.
Return the mounted modules to the clean work surface, including any previously mounted
modules.
Drill and tap the mounting holes for the screws (M4 or #8 recommended).
Place the modules back on the panel and check for proper hole alignment.
Attach the modules to the panel using the mounting screws.
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.
Repeat the steps for all remaining modules.
Mount DIN rail 7.5 mm or 15 mm.
Mount the terminal unit.
The terminal unit is snapped into the DIN rail in the same way as the Terminal Base.
Once secured to the DIN rail, slide the terminal unit to the left until it fully locks into place
creating a solid mechanical and connection.
When attaching the devices, make sure the bus connectors are securely
locked together to ensure proper connection. Max. 10 terminal units can
be attached.
