From an electrical standpoint, industrial machine equipment and tools - from drill presses to multi-motored automatic machines - can present special fire and shock hazards.

Modern electrical machine tool equipment may vary from that of a single-motor machine (such as a drill press that performs simple, repetitive operations) to very large, multimotored automatic machines, which contain highly complex electrical control systems. Typically, these machines are especially designed, factory-wired, tested by the builder and then erected in the plant.

You must totally enclose conductors and their connection external to the control panel enclosure in suitable raceways or enclosures. Unless used for flexible connections involving small or infrequent movements, or connections to normally stationary motors, limit switches and other externally mounted devices, fittings used with raceways or multiconductor cables must be liquidtight.

Figure 5 below shows a schematic diagram for a PLC based motor control system, similar to the previous motor control example.

The control panel may be isolated but the lamp will require power so that the engineer can see while working on it.

If the screen is to be connected then make it off in the same way as for coaxial cable with a soldered pigtail and a sleeve.

Two of the phases are also connected to the transformer to power the logic. The start and stop buttons are at the left of the box (note: normally these are mounted elsewhere, and a separate layout drawing would be needed).
