EV.6.2.1 All Tractive System components must be rated for the maximum Tractive System voltage EV.6.2.2 If the Accumulator Container is made from an electrically conductive material:
a. The poles of the Accumulator Segment(s) and/or cells must be isolated from the inner wall of the Accumulator Container with an insulating material that is rated for the maximum Tractive System voltage.
b. All conductive surfaces on the outside of the Accumulator Container must have a low resistance connection to the GLV System Ground, see EV.7.7
c. Any conductive penetrations, such as mounting hardware, must be protected against puncturing the insulating barrier.
EV.6.2.3 Each Accumulator Segment must be electrically insulated by the use of suitable material (not air) between the segments in the container and on top of the segment.
The intent is to prevent arc flashes caused by inter segment contact or by parts/tools accidentally falling into the container during maintenance for example.
EV.6.2.4 Soldering electrical connections in the high current path is prohibited.
Soldering wires to cells for the voltage monitoring input of the AMS is allowed, these wires are not part of the high current path.
EV.6.2.5 Every wire used in an Accumulator Container, whether it is part of the GLV or Tractive System, must be rated to the maximum Tractive System voltage.
