1. Installation
1.1 DIN Slot Mounting
Mounted by 35mm-width DIN slots, the expansion module connects
each other with snap-fit, which you can push it along the front direction of
the module to fasten modules tightly. Then, users can open the DIN snap-fit
at the bottom of the module and lock the bottom onto the DIN rail; Rotate
module close to the DIN guide rail and close the DIN snap-fit with a
double-checking, as the following figure：
