Learning outcomes
- Explain the key principles of panel layout, emc and documentation.
- Carry out a structured practical check or configuration task.
- Recognise common faults, risks and evidence needed for diagnosis.
Module 2 · Lesson 4
Panel layout, EMC and documentation
Apply layout, heat, segregation, EMC, terminal and documentation principles to industrial control panels.
Before you begin
Panel dimensions, equipment heat-loss data and wiring standards.
Safety: Use site procedures, approved test equipment and competent supervision. Never bypass a protection or interlock without formal control.
Step-by-step learning
- Place heat-producing equipment to support natural or forced airflow.
- Separate VSD motor cables from analogue and network cables.
- Use shield termination and gland arrangements appropriate to the signal and site standard.
- Create a complete document pack: BOM, drawings, settings, software versions and test sheets.
Ian's practical tips:
- A tidy panel is not cosmetic—it makes inspection, cooling and fault finding safer.
- Document every non-default drive, relay and network setting.
Fault-finding questions
- What should be happening, and what evidence proves it?
- Where is the last known correct signal, voltage, state or process condition?
- What changed immediately before the fault?
- Can the system be divided into smaller testable sections?
Practical activity
Create a one-page test record for this lesson. Include expected values, measured results, equipment used, risks controlled, defects found and the final proven condition.
