How to Power On an Industrial Ethernet Switch | Step-by-Step Wiring Guide for Terminal Block Input
If you’ve ever tried to power on an industrial Ethernet switch, you might have noticed—it’s not as simple as plugging in a DC barrel jack or NEMA plug like a typical office switch.
In this tutorial, we’ll walk you through how to correctly wire and power on an industrial DIN-rail Ethernet switch using a DC terminal block connector.
Industrial switches use DC power input and terminal blocks, requiring you to correctly identify the positive (+) and negative (–) poles, loosen the screws, insert the ferrule wires, and tighten them securely. This video is designed for engineers, system integrators, and anyone new to industrial networking who wants a clear, safe, and step-by-step guide.
We made this video because many people get confused when setting up their first industrial switch — unlike business or home switches, these are built for rugged environments and need proper wiring.
