Normally DC BUS FAULT is fixed by replacing C14 and C10. C14 is the 100uf/63V and C10 is 2200uf/16V. They are located between the heat dissipator and the logic board near transformer TX1.

sometimes gives the message some time after and its because the charger isn´t working properly. the charger is a spare board in the 9120, 5 and 6 KVa.
