What information must be included on the marking of the galvanic isolator?

The marking of a galvanic isolator must include the manufacturer's identification. This is crucial for several reasons. First, the manufacturer’s identification ensures traceability, allowing users to contact the manufacturer for support, replacement parts, or warranties. It also helps in verifying that the device meets industry standards and regulations, as established by the manufacturer. Such identification typically includes the brand name or logo, model number, and possibly the country of origin.

While other options, like estimated lifespan, purchase date, and maintenance procedure, may offer useful information to the user, they are not standardized requirements for the marking of galvanic isolators. The focus on manufacturer identification aligns with industry standards on safety and reliability, ensuring device accountability and traceability in the marine electrical industry. This is essential for both regulatory compliance and effective maintenance practices.
