IMPORTANT SAFETY CONSIDERATIONS 

You must consider the possible negative effects of power, wiring, 
component, sensor, or software failure in the design of any type of  
control or monitoring 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.
