Customer ServiceY capacitors, also known as grounding capacitors, are one of the key components of EMI filters. Their primary function is to provide a low-impedance path from the line to the ground, allowing high-frequency noise to be diverted, thereby preventing it from propagating into or out of the device.

Customer ServiceGrounding a capacitor involves connecting one of its terminals to the ground or earth. This is typically done using a wire. The ground serves as a reference point and helps to stabilize the voltage across the capacitor. It also provides a path for the discharge of the stored energy in the capacitor, which can be important for safety reasons.

In the realm of electrical electronics, a capacitor is a passive device that stores electrical energy in an electric field. It consists of two terminals and is commonly used in AC electric circuits that power electric
Customer ServiceSensitivity to power noise and ripple can be minimized by connecting the proper type of localized decoupling capacitor directly between the power pin and the ground plane with a connection that is as short as possible.

It tests out fine (and the case IS bonded to ground internally) but I see the outputs are labeled DC- and DC+ and indeed DC- is not bonded to ground so the outputs are floating (though I''m not detecting a high voltage differential).

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.

Using the lifting eyes on the capacitor bank frame, lift the capacitor bank, positioning it at the pole so that the bolts can slip into the slots on the capacitor bank pole-mounting bracket. (Figure 3) Lower the capacitor bank onto the bolts. Tighten the nuts on the bolts securely. Figure 2. Pole-mounting bracket
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.
Tighten the capacitor terminal clamp nuts to a torque of 16–19 ft.-lb. Check for proper wiring of the capacitor units.
