On the right, click on "Import". Next click on "Browse"

Select the TBSX509CA2-pdf.p7b file
Finally use "Edit Trust" or "Trust" in the lower area and tick the case "Signatures and as a trusted root". Then affect the following rights:

(Note: in Acrobat Reader 7, certificates that are not linked to the Adobe root do not inherit of the trust settings. It might be necessary to define rights for each root generating end-entity certificates)
