Should 0v be connected to ground?
Connecting the local ground and AC line ground is not a good idea as this can cause a ground loop. In such a case, it is usually better to connect the outer chassis to the local ground. The frame of a power supply might still be connected to the AC line ground, but then that shouldn’t be shorted to the chassis.
What is the difference between ground and 0V?
-Ve is a voltage negative with respect to ground. Ground or 0V is typically the reference potential within a circuit. When you connect the “+” pole of a battery to gnd, then the “-” pole of the battery is negative with respec to ground. You can use this a -Ve.

Can a power supply be connected to the chassis?
In such a case, it is usually better to connect the outer chassis to the local ground. The frame of a power supply might still be connected to the AC line ground, but then that shouldn’t be shorted to the chassis. Or, you ignore the AC line ground completely and tie the power supply frame and whole chassis to the local ground.
What are the benefits of grounding a DC power supply?
A second benefit grounding the DC system is that a large network of interconnected ground signals creates a very consistent reference point. If you are measuring voltage with a meter, and the voltage at a junction is changing because of interference, but the reference is not, this would be a very noisy signal.
When to connect DC output to bonded ground?
When the same interference is on both lines, this is referred to as common-mode signaling, and noise is measured when only one of those signals is measured without reference to the other. Ofen, it is recommended to connect the DC – output to a bonded ground in order to reduce or eliminate this common-mode noise.
