To insulate and strip the batteries ensemble there are different special tools:  \nTool number 1076921-00-B. Insulation multimeter.  \nTool number 1130480-00-A. Cable for insulation multimeter.  \nYou must be sure that all the testing devices and equipment are compatible with high-voltage applications.  \nWhen the batteries are insulated, a recommended waiting time must pass by before proceeding to handling the electric propulsion system.  \nWith the insulation multime","cbCaiuzZTeEFsLSP","https://ap.wps.com/l/cbCaiuzZTeEFsLSP","pdf",3147411,16,"English","# 03 General information\n## WARNING!
