in a critical part of a process, fan replacement is recommended once these symptoms appear. Spare
fans are also available.
9.3.1 Replacing the cooling fan
Read and follow the instructions in chapter Safety precautions. Ignoring the
instructions would cause physical injury or death, or damage to the equipment.
1. Stop the inverter and disconnect it from the AC power source and wait for at least the time
designated on the inverter.
2. Loose the fan cable from the clip.
3. Disconnect the fan cable.
4. Remove the fan.
5. Install the new fan in the inverter, put the fan cables in the clip and then fix the inverter well.
6. Connect the power supply.
9.4 Capacitors
9.4.1 Capacitors reforming
The DC bus capacitors must be reformed according to the operation instruction if the inverter has
been stored for a long time. The storing time is counted form the producing date other than the
delivery data which has been marked in the serial number of the inverter.
Storing time less than 1
year
Operation without charging
Connect with the power for 1 hour before first ON command
Use power surge to charge for the inverter
• charging 25% rated voltage for 30 minutes
• charging 50% rated voltage for 30 minutes
• charging 75% rated voltage for 30 minutes
• charging 100% rated voltage for 30 minutes
Storing time more than 3
years
Use power surge to charge for the inverter
• charging 25% rated voltage for 2 hours
• charging 50% rated voltage for 2 hours
• charging 75% rated voltage for 2 hours
• charging 100% rated voltage for 2 hours
Use voltage-adjusting power supply to charge the inverter:
The right selection of the voltage-adjusting power supply depends on the supply power of the inverter.
Single phase 220V AC/2A power surge is applied to the inverter of single/three-phase 220V AC. The
inverter of single/three-phase 220V AC can apply single phase 220V AC/2A power surge (L+ to R; N
