IMPORTANT SAFETY CONSIDERATIONS 

You must consider the possible negative effects of power, component, 
wiring, sensor, or software failure in the design of any type of monitoring or 
control system.  This is very important where property loss or human life is 
Involved.  It is important that you perform satisfactory overall system design 
and it is agreed between you and Acromag, that this is your responsibility.
