Line phase failure

What does F06 mean?

An immediate switch-off with inhibit, only for 3-phase inverters, indicating a missing phase in the line supply or an insufficient line voltage.

• Phase failure in the incoming line supply
• Line voltage too low

1. 1

   Check the line cable for phase continuity at the inverter input terminals

2. 2

   Check the line voltage at the inverter input terminals for correct levels
