Suggestion
1. Check whether the low-voltage
power loop is short-circuited. If
yes, locate and rectify the fault.
2. Check whether overcurrent occurs
in the low-voltage power loop. If
yes, rectify the fault.
3. Rectify the fault before turning on
the switch.
4. If the fault persists, contact your
dealer or technical support.
1. Disconnect the MCCB and inverter
in sequence, observe the IMD
impedance change, locate the
faulty loop, and rectify the fault.
2. Check whether condensation or
contaminant particles accumulate
on the surface of the bus subrack
or insulator. If yes, disconnect the
power supply and then perform
dehumidification or clean up
foreign matters.
3. Check whether the insulation
resistance of the low-voltage loop
cable is normal. If no, rectify the
fault.
4. If the fault persists, contact your
dealer or technical support.
