In addition, when three or more modules with 130mm or more in depth (such as Q66DA-G etc.) are mounted,
or when the base unit is used in the environment with extremely frequent vibration, use the Q6DIN1A Q-type

The large mounting bracket enables to enhance the resistance to vibration. Depending on the environment, it is
recommended to mount the base unit directly on the control panel.
