Then the obvious thing to do would be to connect a multimeter between the earth terminal and the rest of the assembly.

I don't believe that our overseas manufacturer's are ardent followers of symbols/markings used elsewhere. I reckon it's just generic labeling on a whole batch of boards, some of which are destined for markets whose countries use a cpc and those who don't, a bit like the Chinese Export mark found on most things these days, but it would be interesting see if if one got a continuity reading.

Most likely highlighting my ignorance here, but would a more obvious answer be that the earth terminal is just there to ‘park’ the cpc where a light fitting is changed but is using the existing wiring from a fitting which previously utilized it?

gkenyon:

Reasonable assumption, but the IEC 60417-5017 symbol on the bottom-left of the driver is used where the equipment must be earthed.

Yes, but does it need to be earthed if it is a component of a Class II luminaire? That is why I asked about the markings on the complete product.

Been there, done that with the original version.

I would really like them to have said they are double insulated with a parking terminal for the CPCs, it would make it a much more versatile product.

Then they changed the drivers and introduced this one with an earth terminal, but then did not connect it.

If the complete product is marked as Class II, then strictly not.

However, it does raise the question as to whether it's correct to put a Class I product inside a Class II product without earthing it.

For example, some safety isolating transformers require an earthed screen to achieve the full level of protection for SELV.

Without asking the question of the manufacturer of the “finished product” in which these drivers are incorporated, all you are left with is questions I'm afraid. As I said earlier, I wouldn't be happy and would either select another product, or obtain what I thought was a reasonable answer to my questions of the luminaire manufacturer.

As David and others have pointed out, there may well be nothing to worry about with the product. But at the end of the day, when an EICR is carried out, the inspector may well “FI” it, or even C2 it, so best to get it out of the way when you install it, as the installer will be seen as doing something wrong whatever the right of the matter is.
At least if you check with the manufacturer, and everything is OK, you can print a label saying “Class II product, checked with manufacturer on <date>. Do not Earth this product.” and stick it inside.

The answer:

Even though this driver does not require an earth, the emergency version does so we list the whole range as class one?

I'll post this again, as I marked it as resolved the forum software inserted my post as the first reply.

That answer is obviously completely unsatisfactory and the CE marking is invalid.  Each individual product must be fully compliant with the markings and this one isn't! It is currently illegal to sell it until we lose the CE regulations, but then there is no enforcement now (or ever much) anyway. In an EICR it could easily generate a C2 as said above. The provided CE certificate also appears to be false, in that it is non-compliant with the regulations so we must assume it is a China Export mark, which is also illegal as the mark is trademarked to the EU, and obviously used to deceive the purchaser. Rather a sorry story really. I also wonder why the maintained fitting needs an Earth, presumably the battery circuits have some isolation problems? All very strange. A recovery of British manufacturing would be a very good thing.

until we lose the CE regulations

I thought we had - isn't it a “UKCA” (and UKNI) mark now?

Postponed taking its introduction to January 2023 due to not getting it organised.

It's not a proper CE mark anyway - its dimensions are wrong.  The C is too close to the E.
