Circuit Diagram 3 - Best Practices

The nuts and bolts of a good wiring diagram is its clarity. Therefore, some "Best Practices" have prevailed...

Conductors

You connect components with lines...

• Lines are drawn vertically or horizontally.
• Only in special cases, 45 degree lines can be used.
• Never draw lines through components.

Components

All components must be clearly marked...

• All components are uniquely marked with a reference number.
• Increase the reference numbers from top left to bottom right.
• Mark important components with a special reference.

Power Supply

For the power supply applies...

• Draw the positive voltages on top, the negative voltages at the bottom.
• You can leave out the power supply as a component.

In- and Outputs

For the inputs and outputs apply...

• Draw inputs on the left, outputs on the right...
• Arrange functional blocks of a circuit so that the input is left, the output is right.

These are some of the most important best practices. However, they become clearer by some examples...
