I have a question about the mechanical installation of the DIN rail modules. I have a client who is upgrading from a Homeworks Interactive system with 3 enclosures full of RPM's.We're getting a proposal together to upgrade to QS, QSX if the timing is right.Question - Is it possible to use the Din Rail modules in the original RPM enclosure.? Has anybody tried this and is it a matter of adding the Din rails and rewiring? Does Lutron has an upgrade path?Any help/ suggestions would be appreciated.Thanks
