Convo Inverter Cvf-s1 Manual _verified_ -

First-time VFD users without someone experienced to help.
Applications requiring advanced features like Modbus or PID with complex feedback loops.

Danger: High voltage remains on DC bus capacitors for up to 5 minutes after power is removed. Wait 10 minutes before opening cover.
Do not perform a hi-pot / dielectric test on the inverter.
Ground the inverter correctly (terminal ⏚). Earth leakage current >3.5mA – use a dedicated grounding wire.
Do not connect input power to output terminals U/V/W.
Do not install a contactor or switch between inverter and motor while running.
Do not use the inverter with a motor insulation rating less than 1300V (use inverter-duty motors).

Used for fault output or status indicators. Basic Troubleshooting
