Hello Simon, even though you might have damaged one or more modules I
don't think this is the reason for the constantly blowing fuses.

Assumed by now all modules are connected correctly I suggest to try
other fuses: "630 - 700 mA time lag (slow blow)". [That info is from
Dopefer's HP -> FAQ.] Make sure they are SLOW BLOW/TIME LAG!

Hope that helps, Ingo
