We have noticed that when we are doing some wiring on channels 1 or 2 on module base ITU805 input fuse burns out. After that we have opened module base as you can see from the video (which I can't upload). As soon as you press harder on C1 or C2 positive terminal touches metal frame of the base which is connected to DIN rail and therefore with mounting plate in the cabinet. Since negative pole of power supply is grounded we get short circuit (you can see mark on metal plate in the picture from attachment). We are not asking you to solve us this, just for the users which have this kind of modules to pay extra attention when dealing with wiring of channels 1 and 2.
