Mounting on DIN rails 
Installation 
 
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.
