Which temperature must be marked on the galvanic isolator and its status monitor?

The maximum ambient operating temperature must be marked on the galvanic isolator and its status monitor because it indicates the highest temperature at which the device can operate safely and effectively. This temperature is crucial for ensuring the reliability and longevity of the galvanic isolator, as exceeding this limit could lead to overheating, failure of the device, or potential safety hazards.

Additionally, labeling the maximum ambient operating temperature helps users understand the environmental conditions under which the component should function. It allows for proper installation and usage, ensuring that the isolator is not placed in environments that could compromise its operation. Recognizing the limits of temperature is essential for maintaining electrical safety standards and optimal performance in marine applications.

The other temperature parameters such as minimum storage temperature, operating pressure temperature, and the temperature at normal conditions do not directly relate to the operational limits and do not emphasize the critical aspect of maximum working temperature required for safety and performance standards in electrical systems on vessels.
