These conductors must be yellow throughout the entire circuit, including wiring in the control panel and the external field wiring. • White or natural gray represents a grounded circuit conductor. • White with blue stripe represents a grounded DC current-carrying circuit conductor. International and European standards require you to use light blue for the neutral conductor. • White with yellow stripe represents grounded AC current-carrying control circuit conductors that remain energized when the disconnecting means is in the OFF position. For additional circuits powered from different sources that remain energized when the main disconnecting means is in the OFF position, you must use striping colors other than green, yellow or blue to uniquely identify the grounded conductors.

Ensure that identification tags and cable markers are legible, marked with a permanent ink and suitable for the environment where the panel is to be used. They should also correspond with those shown in the machine drawings and instruction or service documentation.

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).

Electrical Standard for Industrial Machinery, helps you ensure fire safety by addressing the electrical considerations specific to equipment, apparatus, and systems used in industrial manufacturing processes.

The starter solenoid is a relay switch that contains 2 circuits and has 3 or 4 wires connecting to and from it. Two of these wires are heavy gauge, and the remaining are smaller gauge. The two heavy gauge wires are connected to your starter and to your battery. The remaining small gauge wires are connected to the small terminals on the starter solenoid and lead to the ignition switch and to the common ground. If your starter solenoid only has one small wire or terminal, the ground is through the solenoid’s mounting bracket.

Wiring diagrams, sometimes called “main” or “construction” diagrams, show the actual connection points for the wires to the components and terminals of the controller.

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