    SELV is by definition class 2 Andy, there are terminals marked Earth but why is a good question,  but it is not a problem for you to wire up is it? Both units are mounted on a PCB, but you do not show us the casing if any. 

    The SELV output may be class II, but that does NOT mean the mains input is. 

    I would certainly either question this product as Sparkingchip has done … or not use it, purely based on the markings on the drivers required by the product standards. They are there for a reason, to indicate (in this case) the safe installation and use of the product.
