Cause : Line currents not symmetrical comes when asymmetry of the currents in the line phase too high. The most probable cause is failure of a line phase.
- check the line supply and fuses.
- check the connection and size (rating) of the line reactor.
- check the previous alarm A06205 and the alarm value.
