lets just ignore that one thread. You should familiarize your self with the units construction, identify where the line voltage is present and avoid that area. Follow the good practices as suggested.The reasoning behind my knee jerk is that I was reading another thread from about 10 years where someone was asking the exact same questions and the guy answering got really alarmed and just told him to close it up because he was not going to be part of his electrocution. So I took that to heart a little.
