You're permitted to use wiring channels if they're made of a flame-retardant insulating material. If you're working with back-connected control panels, you must provide access doors or swing out panels that swing about a vertical axis. Multiple-device control panels must have terminal blocks or attachment plugs and receptacles to terminate and connect all outgoing control conductors.

A highly disturbing device (variable speed drive, frequency converter, etc.) will have less radiation in the panel if it is “encapsulated” in a small, electromagnetically sealed, unpainted metal enclosure.

This is essential for industrial control systems that may contain hundreds or thousands of wires. These numbering schemes are often particular to each facility, but there are tools to help make wire labels that will appear in the final controls cabinet.

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

When checking these subsystems keep an eye out for evidence suggesting trouble such as sludge or debris in fuel, missing or damaged air cleaner, score marks on top of piston and cylinder walls, and excessive carbon build up on the intake and exhaust valves. All of these give you valuable insight to your problem.

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).

However, an exception allows you to install a splice in leads attached to electrical equipment, such as motors and solenoids.
By Sylviane Marcelline. Electrical Wiring. Published at Tuesday, January 23rd 2018, 22:25:49 PM. Workshops manufacturing parts in PVC or rubber use high-frequency welding processes to perform assembly. The propagation of strong magnetic fields and high-frequency waves is not easily controllable.

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