IEC Electrical Schematics and Industrial Control Panels

This course gets you up to speed on understanding what makes up an industrial control panel.  An overview of IEC Basic panel design criteria and standards is provided.

• IEC schematics and how to read them is covered. 

• These electrical schematic diagrams are often used in small to large scale electrical control systems.  Stand alone machines, infrastructure equipment, integrated assembly lines, resorts, theme parks and building automation systems, use these types of electrical schematic diagrams.

• An example IEC industrial control panel schematic set is provided in the course.

Important topics are covered in this course:

• The main parts and basic construction of an IEC industrial control panel

• Introduction to IEC industrial control panel standards

• Overview of utilization categories for low voltage switch gear

• Back panel component layouts, including din rail and wire routing ducts is explained

• PLC graphic layout and back panel layout are detailed

• Basic emergency stop control circuits are outlined

• Safety control module integration is covered

• Safe torque off or STO variable frequency drive safety function is covered

• What makes up an industrial control schematic set

• IEC 60617 graphical symbols use in diagrams

• How IEC page coordinate systems work

• Electrical device cross referencing systems

• On and off page connectors, source and destination arrows and parent and child components

• The mains power section, control wiring section and PLC control section are covered

• Mains power sequential wire numbering based on functional description is covered

• Control wire marking based on sequential numbering and page prefix numbering is covered

• Motor controllers such as DOL starters, and VFD are shown in schematic sets
