Where must the installation instructions be located for a luminaire?

The correct choice emphasizes that installation instructions for a luminaire should be either included with the luminaire itself or visibly placed on the exterior packaging. This ensures that the necessary information is immediately accessible to users or installers, facilitating proper installation and compliance with safety standards. Clear visibility of the instructions reduces the risk of mishandling or improper installation, which can lead to hazards such as electrical faults or fire risks.

While providing instructions in a user manual or on the manufacturer's website is useful, it does not guarantee immediate access during installation. Additionally, having instructions solely inside the packaging may result in them being overlooked or not readily available at the time of installation, which could pose the same risks. Therefore, placing the instructions in a prominent position ensures that they are easy to find and follow, thereby promoting safety and effectiveness in luminaire installation.
