V DC or equal or below 30 V AC (rms) within 1 s after the connector is separated.
         5.1.1.1. For protection of live parts inside the passenger compartment or luggage compartment, the protection degree IPXXD shall be provided.
         5.1.1.2. For protection of live parts in areas other than the passenger compartment or luggage compartment, the protection degree IPXXB shall be satisfied
         5.1.1.3. Service disconnect
         For a service disconnect which can be opened, disassembled or removed without tools, it is acceptable if protection degree IPXXB is satisfied under a condition where it is opened, disassembled or removed without tools.
         5.1.1.4. Marking
         5.1.1.4.1. In the case of a REESS having high voltage capability the symbol shown in Figure 1 shall appear on or near the REESS.  The symbol background shall be yellow, the bordering and the arrow shall be black.

         Marking of high voltage equipment
         5.1.1.4.2. The symbol shall also be visible on enclosures and barriers, which, when removed expose live parts of high voltage circuits.  This provision is optional to any connector for high voltage buses.  This provision shall not apply to any of the following cases:
              (a)  Where barriers or enclosures cannot be physically accessed, opened, or removed; unless other vehicle components are removed with the use of tools;
         (b)  Where barriers or enclosures are located underneath the vehicle floor.
         5.1.1.4.3. Cables for high voltage buses which are not located within enclosures shall be identified by having an outer covering with the colour orange.
         5.1.2. Protection against indirect contact
         Protection against indirect contact is also required for vehicles equipped with any REESS type approved under Part II of this Regulation.
         5.1.2.1. For protection against electrical shock which could arise from indirect contact, the exposed conductive parts, such as the conductive barrier and enclosure, shall be galvanically connected securely to the electrical chassis by connection with electrical wire or ground cable, or by welding, or by connection using bolts, etc. so that no dangerous potenti              als are produced.
         5.1.2.2. The resistance between all exposed conductive parts and the electrical chassis shall be lower than 0.1 ohm when there is current flow of at least 0.2 amperes.
         This requirement is satisfied if the galvanic connection has been established by welding.
         5.1.2.3. In the case of motor vehicles which are intended to be connected to the grounded external electric power supply through the conductive connection, a device to enable the galvanical connection of the electrical chassis to the earth ground shall be provided.
         The device should enable connection to the earth ground before exterior voltage is applied to the vehicle and retain the connection until after the exterior voltage is removed from the vehicle.
         Compliance to this requirement may be demonstrated
