Do you have the User Manual or Instruction manual for the

 

ABB DCS 400 and associated Field Supply Unit?

 

 

If so, you have the information you need. Input AC amps and Output DC amps are Listed in the manual.

 

If you don't have the manual(s) ..... Then contact your Local ABB distributor or sales office

 

and request them.

 

You could also find the nameplate on the units where the input and output amps should also be listed.

 

 

As to how to size the wires ...... follow the requirements of your national and local Electrical Codes; of which we have no knowledge.
