Battery Charger and 14 V Power Module Maxi 20 A Fuse Replacement

Removal Procedure

Danger: Always perform the High-Voltage Disabling procedure prior to servicing any High Voltage component or connection. Personal Protection Equipment (PPE) and proper procedures must be followed.

The High-Voltage Disabling procedure will perform the following tasks:

   • Identify how to disable high voltage.
   • Identify how to test for the presence of high voltage.
   • Identify conditions under which high voltage is always present and personal protection equipment (PPE) and proper procedures must be followed.
Before working on any high-voltage system, be sure to wear the following Personal Protection Equipment:
   • Safety goggles with appropriate side shields when within 15 metres (50 feet) of the vehicle, either indoors or outdoors.
   • Certified and up-to-date Class "0" Insulation gloves rated at 1000 V with leather protectors.
      - Visually and functionally inspect the gloves before use.
      - Wear the Insulation gloves with leather protectors at all times when working with the high-voltage battery assembly, whether the system is energised or not.
Failure to follow the procedures exactly as written may result in serious injury or death.

Danger: The Volt Battery Pack will utilise an exchange program.
