WebAug 8, 2024 · The shield is connected to ground via the 100k res/100nF cap. There is a metal tab fitted to the PCB which rests on the metal chassis. According to the old ESD report, this was needed or the device failed. As far as I can see, these were the only things added in addition to that example circuit to protect from ESD. WebShields on power cables are connected to earth ground at each shield end and at splices for redundancy to prevent shock even though induced current will flow in the shield. This current will produce losses and heating and will reduce the maximum current rating of the circuit. Tests show that having a bare grounding conductor adjacent to the ...
