1.
PRECONDITIONING
• Before inspecting the high-voltage system or disconnecting the low voltage connector of the inverter with
converter assembly, take safety precautions such as wearing insulated gloves and removing the service
plug grip to prevent electrical shocks. After removing the service plug grip, put it in your pocket to prevent
other technicians from accidentally reconnecting it while you are working on the high-voltage system.
• After disconnecting the service plug grip, wait for at least 10 minutes before touching any of the high-voltage
connectors or terminals.
• Waiting for at least 10 minutes is required to discharge the high-voltage capacitor inside the inverter with
converter assembly.
