Inspection Procedure

WARNING:
  • Before inspecting or servicing the high-voltage system or disconnecting the low voltage connector of the inverter with converter assembly, be sure to follow all safety measures, such as wearing insulated gloves and removing the 3 service plug grips to prevent electrocution. After removing the 3 service plug grips, carry one of the 3 service plug grips in your pocket to prevent other technicians from accidentally reconnecting it while you are servicing the vehicle. Keep the other 2 service plug grips in a secure place.
  • After removing the service plug grips, wait for at least 10 minutes before touching any of the high-voltage connectors or terminals. After waiting for 10 minutes, check the voltage at the terminals in the inspection point in the inverter with converter assembly. The voltage should be 0 V before beginning work.

HINT: 

Waiting for at least 10 minutes is required to discharge the high-voltage capacitor inside the inverter with converter assembly and the electric vehicle charger assembly.
