Ground close to the battery. The battery poles are supposed to be safe to touch. The battery ground should therefore be the most reliable and visible ground connection. The DC ground cabling should have a sufficient thickness to be able to carry a fault current at least equal to the DC fuse rating.
The answer is not a straightforward yes or no. This article explores the benefits and drawbacks of grounding DC power supplies. DC power supplies are a common, perhaps almost guaranteed, component of any control system, especially one containing a digital controller.
So, the short answer for some 24V DC systems is no, the output is not required to be connected to ground. From the UL 508A specification, there are further answers that also dictate grounding depending on the input voltage of the power supply. Figure 1. Grounding power supplies inside a control cabinet can be a difficult decision.
A 2- wire, dc system supplying premises wiring and operating at greater than 50 volts but not greater than 300 volts shall be grounded. Exception No. 1: A system equipped with a ground detector and supplying only industrial equipment in limited areas shall not be required to be grounded.
