2.1 Installation Requirements
DIN slot installation
It can be installed with a 35mm-width DIN slot in the environment of low
vibration.
Open the DIN snap-fit at the bottom of the module and fix the bottom of
the module to the DIN guide rail; Rotate the module to close the DIN rail and
close the snap-fit. Check carefully that the DIN snap-fit is tightly fixed to the
DIN guide rail, as shown in the following：
