The din rail in the 05 pic is that real tight to the back panel (add star washers to cut through paint), make sure the green/yellow blocks have the middle screw tight.
One mighty thin grounding wire in bpel04.jpg, also could add star washer to cut through paint You could measure the ground resistance too if you can. Others are likely to mention you have two grounds rather than a star ground. Make sure cases are tight to frame to guarantee continuity Dave Caroline ------------------------------------------------------------------------------ _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
