Rail Mounting
Considerations
If you are using 7.5 mm DIN rail, make sure that the region along the rail where the
island bases will be installed does not have any screw heads on it. The base units
may not make proper contact with the rail if there are screw heads behind them.
For high vibration environments where the rail needs to be fastened to the mounting
surface along areas where the island modules will be mounted, use 15 mm DIN rail.
The bolt heads on 15 mm rail will be sufficiently recessed so that they do not
interfere with the base-to-rail contacts.
