(7) If you want to mount base units on a DIN rail, please note the
following points.
(a) Suitable DIN rail types are listed as follows(JIS C 2812):
TH35-7.5Fe
TH35-7.5Al
TH35-15Fe
*JIS: Japanese Industrial Standard
(b) Spacing intervals for DIN rail mounting screws
When using a TH35-7.5Fe or TH35-7.5Al DIN rail, rail
mounting screws should be placed at a pitch of 200 mm (7.87
inches) or less in order to ensure that the rail has sufficient
strength.

35mm
(1.38inches)
(8) When installing the base unit to DIN rail in an environment with
large vibration, use a vibration-proofing bracket (A1S-PLT-D).
Mounting the vibration-proofing bracket (A1S-PLT-D) enhances the
resistance to vibration.
Depending on the environment to set up the base unit, it is also
recommended to fix the base unit to the control panel directly.
