2.5.2 Supply voltage with the characteristic value KK
You will find information on the characteristic values here:
“Device name and product code” on page 19
 
You have the option of supplying the supply voltage redundantly, without 
load distribution.
Both supply voltage inputs are uncoupled.
With a redundant supply, the supply voltage 1 (upper voltage input on the 
device) has priority.
