Drive Motor A Inverter Power Supply Circuit Low

Check these first

• A low or unstable high voltage supply to the drive motor A inverter
• An inverter internal fault that loads the supply
• A chafed or loose high voltage supply connection
• A high voltage interlock that is not fully seated

What to do next

1. Check for companion high voltage codes stored with this one
2. Inspect the high voltage supply connections for looseness and heat
3. Verify the high voltage interlock loop is complete
4. Check the contactors that feed the inverter
5. Service the inverter only after the supply and connections test good
6. Clear the code and retest
