Danger of injury by falling objects
The 35 mm DIN rail does not provide adequate support in shipping or when there is severe
vibration (> 10 g). When used under these conditions, the device can detach itself and may
cause injury to persons.
When used in shipbuilding or when extreme vibration can be expected, mount the device
on a S7 standard rail.
