Yes, so having documentation on that the Essential Requirements of the LVD has been fulfilled (as per Annex I clause 1.5.1 of the MD) would still be required for compliance with the MD?
Also, even if being a Fixed Installation according to the EMCD, the manufacturer of this Fixed Installation would still need to provide documentation that Good Engineering Practice has been followed during the installation of the sub-parts of the product, even if the product itself doesn't need to be EMC tested or go through a conformity assessment process?
