Goodrive350 IP55 High-ingress Protection Series VFD Maintenance and hardware fault diagnosis
-270-
The method for using a resistor (incandescent lamp) to charge the drive is described as
follows:
If you directly connect the drive device to a power supply to charge the DC bus capacitor, it
needs to be charged for a minimum of 60 minutes. The charging operation must be performed
at a normal indoor temperature without load, and you must connect a resistor in series mode in
the 3PH circuit of the power supply.
For a 380 V drive device, use a resistor of 1 kΩ/100W. If the voltage of the power supply is no
higher than 380 V, you can also use an incandescent lamp of 100W. If an incandescent lamp is
used, it may go off or the light may become very weak.

8.4.2 Electrolytic capacitor replacement
Read 1 "Safety Precautions" carefully and follow the instructions to perform
operations. Otherwise, physical injuries or damage to the device may be caused.
The electrolytic capacitor of a VFD must be replaced if it has been used for more than 35,000
hours. For details about the replacement, contact the local INVT office.
8.5 Power cable
Read 1 "Safety Precautions" carefully and follow the instructions to perform
operations. Otherwise, physical injuries or damage to the device may be caused.
1. Stop the VFD, disconnect the power supply, and wait for a time no shorter than the waiting
time designated on the VFD.
2. Check the connection of the power cables. Ensure that they are firmly connected.
3. Power on the VFD.
