Mounting Hole Connected to Ground Through Capacitor
The board''s ground plane layer (which serves as the digital/analog/power ground) connects to the DC negative return. The power supply itself has a terminal for a chassis ground connection, which is connected to the one-point system ground. The +/-DC supply, however, is isolated from this chassis ground. $endgroup$ –

The individual star grounds should still be connected to the capacitor grounds. The preamp sections: The individual tube preamp stages have their own "local" grounds, where the cathode resistor and capacitor ground sides are connected. Each stage "local" ground should be run back to the star point on a separate wire.

However, I still have a question: should be signal ground network connected to PE or not? Or should it be connected through, let''s say, a 10 MΩ, 1 W resistor? If the device doesn''t have galvanic isolation there should not be any connection between SGND and PE, right? If there is a galvanic isolation the question becomes tricky for me.

6 FAQs about [What pole should the capacitor be connected to when grounding]
Is a capacitor a ground terminal?
The capacitor is for EMI filtering, it is there to reduce common mode noise. Yes they are ground terminals. One is the ground reference for unisolated mains input side, the other one is the ground reference for isolated low voltage output side. Therefore it must be of special type for safety reasons, the type is called an Y capacitor.
How do you ground a capacitor bank?
Ground the neutral of ungrounded capacitor banks. For a fixed pole-mounted capacitor bank, ground the jumper leads on the source side of the capacitor unit between the fuses cutout and capacitor unit terminal.
When should a capacitor bank be grounded?
Open the fuse cutouts. DO NOT ground the capacitor bank immediately after the bank has been disconnected from the system. For capacitor banks with capacitor units containing discharge resistors designed to discharge the capacitor unit from peak rated voltage to less than 50 V in five minutes, allow five minutes before grounding.
How do you attach a capacitor brace to a pole?
Place the other end of the brace against the pole at an angle of approximately 45° and fasten with a 1/2-in. lagscrew or thru bolt. For a snug fit, force the end of the brace attached to the capacitor bank toward the pole and tighten the nut and bolt in the capacitor bank frame. Repeat steps 1, 2, and 3 for the other brace. 45° APPROX.
Should a bypass capacitor be connected to Node_G?
The bypass capacitor should be connected to node_G. Though there may be additional parasitic impedance on its way to other ground points, variation in voltage at node_G affects the critical nodes equally, so it does not inject an error or distortion. I’ve shown an op amp with a single power supply.
What happens when a capacitor is charged?
When a capacitor is being charged, negative charge is removed from one side of the capacitor and placed onto the other, leaving one side with a negative charge (-q) and the other side with a positive charge (+q). The net charge of the capacitor as a whole remains equal to zero.
