Troubleshooting
▶
During Discharging mode, voltage of Inv1 and Inv2 will be displayed alternately.
▶
Even when the power is o, it is dangerous when you come in contact with inverter PBA, fan PBA since high pressure DC voltage is charged
to those parts.
▶
When replacing or repairing the PBA, cut-o the power and wait until the DC voltage is discharged before replacing/repairing them.
- Wait for more than 15 minutes to allow those parts to be fully discharged.
