Proposal as approved by the GRSP to remove unnecessary constraints on electric vehicle systems having a working voltage of 48V and to adapt the safety provisions of the regulation to this technology.

Editorial improvements to the text and introduction of provisions allowing for the separation of connectors (including the vehicle inlet) without the use of tools under prescribed conditions specified under paragraph 5.1.1. This paragraph describes the general requirements for the protection of all high voltage parts, including the obligation that such protection against live parts cannot be opened without the use of tools. If connectors can be opened without use of tools or if they do not satisfy the IPXXD/IPXXB protection limits, the provisions of 5.1.1.3 have to be met.

Proposal to amend the transitional provisions in order to explicitly confirm that approvals granted prior to the respective supplements to the 01 and 02 series of amendments and the establishment of the new guidelines on UN Regulation procedures (documents WP.29/2017/107 including Corrigendum 1 and Addendum 1) will continue to be accepted. This amendment confirms the understanding that the new procedures apply only to new approvals and do not affect previous approvals.
