G'day folk. Following on from recent postings on 'Systems', and in order to muddy the waters a bit, I'll bring up the subject of 'Excluded Installations'.
If you buy a computer, or a machine, that is comprised of a plurality of parts, each CE marked, assembled by a manufacturer for a particular function, then that would seem to be a system, and should be tested and certificated as such. If, however, you procure those self same parts, each CE marked, and assemble them at the place where it is to be used, it comprises an Installation, which need not be tested and certified as a whole, but nevertheless needs to conform to the Protection Requirements. I would ask the groups opinion on the following.... If I assemble a machine/apparatus from a group of CE marked components, strip it, ship it, rebuild it in the customers plant in exactly the same form as it was originally assembled at source, is this a 'System', or an 'Excluded Installation'? The CE marking requirements are dealt with, i.e. customs see separate boxes each with CE marks. EMC Conformance is dealt with as we would have added ferrites etc. as required to get the Emissions etc. under control. But do we need to test, certificate and CE mark the whole set of equipment as a single entity, or simply show a bundle of component part CE certificates? What say you all?
