The implication of 'individual, self-contained items' is that they are marketed individually (and are therefore each CE-marked). Unfortunately, we could not get agreement on more specific wording. These items may be supplied by one or more than one manufacturer, and are often racked-up on-site; thus the rack is an 'installation' as defined in the Directive and Guidelines. If a manufacturer sells as a single item of commerce a rack of physically-separable items which are not marketed individually, then that is a 'system' as defined in the Directive and the Guidelines and is tested and CE-marked as a whole. -- Regards, John Woodgate, OOO - Own Opinions Only. http://www.jmwa.demon.co.uk Interested in professional sound reinforcement and distribution?
