With age,humidity or temperature or whatever, the screening card lining the
inside of the plastic case can curl up and touch solder and traces on the
IEC sub-board, aluminium side to mains voltages. Cut away all around that
corner on the rear and side card.

The EMX 88S has proper rigid metal work around that IEC area

For us folks on the west side of the Atlantic Ocean, what is a
screening card?
