Engineers and compliance managers looking to implement these design choices must consult the official, full-text specification. The authorized publication can be obtained directly from the or national standards bodies (such as ANSI, BSI, or DIN).
Indicates a state requiring operator intervention that is not safety-critical. Examples include a prompt to load raw materials or reset a cycle counter.
Organizations such as ANSI (USA), BSI (UK), DIN (Germany), or ISO members sell localized versions of the standard (e.g., BS EN 60073).
While free copies are tempting, the risks of outdated or counterfeit files far outweigh the cost. Purchase the official PDF from the IEC Webstore or your national standards body. Then, apply its principles rigorously. Your operators—and your liability insurer—will thank you. iec 60073 pdf
Placing critical controls in standardized, easily accessible locations.
Used for mandatory resetting actions (e.g., resetting a thermal overload relay after it trips).
: Emergency, danger, or fault. Used for critical conditions like a DC supply failure or a trip condition that requires immediate action . Engineers and compliance managers looking to implement these
Under IEC 60073, you must never use a red indicator for "normal power on" or green for an emergency stop. Violations can lead to failed safety inspections and liability in accidents.
In industrial automation and electrical engineering, clear communication between machines and human operators is critical. A single misunderstood signal can lead to costly downtime, equipment damage, or severe workplace injuries. To standardize how machines communicate status and accept commands, the International Electrotechnical Commission established .
Indicates an immediate hazard or critical condition that requires urgent action (e.g., a dangerous malfunction, fire, or safety device tripped). Examples include a prompt to load raw materials
While summary guides are useful for a general overview, designing compliant control panels requires the official text.
Actuator color overrides indicator color: A red emergency stop button is always red, even if its internal status indicator is green.
