How do I wire a Powerpact D frame or Compact NSJ with STR53UP trip unit to a Masterpact or Powerpact breaker with a Micrologic 5.0/6.0 A/P/H trip unit for Zone Selective Interlocking (ZSI)?

Z11 gets wired to Z5, and Z12 gets wired to Z3. Note that the Powerpact D frame/Compact NSJ has no ZSI input and can only act as a down stream breaker with regard to ZSI.
