The method of using power surge to charge for the inverter:
The right selection of Power surge depends on the supply power of the inverter. Single phase 230V AC/2A power
surge applied to the inverter with single/three-phase 230V AC as its input voltage. All DC bus capacitors charge at
the same time because there is one rectifier.
High-voltage inverter needs enough voltage (for example, 400V) during charging. The small capacitor power (2A is
enough) can be used because the capacitor nearly does not need current when charging.
Change electrolytic capacitors
 Read and follow the instructions in chapter Safety Precautions. Ignoring the instructions may
cause physical injury or death, or damage to the equipment.
Replace electrolytic capacitors after 35000 hours operation. Please contact IMO for assistance.
6.1.3 Power cable
 Read and follow the instructions in chapter Safety Precautions. Ignoring the instructions may
cause physical injury or death, or damage to the equipment.
1. Stop the drive and disconnect it from the power line. Wait for at least the time designated on the inverter.
2. Check the tightness of the power cable connections.
3. Restore power.

6.2 Fault solution

 Only qualified electricians are allowed to maintain the inverter. Read the safety instructions in
chapter Safety precautions before working on the inverter.
6.2.1 Alarm and fault indications
Fault is indicated by LEDs. See Operation Procedure. When TRIP light is on, an alarm or fault message on the
panel display indicates abnormal inverter state. P07.27~P07.32 records the last 6 faults and P07.33~P07.56
records the operation data of the last 3 faults. Using the information reference in this chapter, most alarms and
fault causes can be identified and corrected. For further assistance, contact IMO.
6.2.2 Fault reset
The inverter can be reset by pressing the keypad key STOP/RST, through digital input, or by power cycing. When
the fault has been cleared, the motor can be restarted.
6.2.3 Fault instruction and solution
Perform the following after inverter fault:
Connect with the power for 1 hour before first ON command
Use power surge to charge for the inverter
• Add 25% rated voltage for 30 minutes
• Add 50% rated voltage for 30 minutes
• Add 75% rated voltage for 30 minutes
• Add 100% rated voltage for 30 minutes
Use power surge to charge for the inverter
• Add 25% rated voltage for 2 hours
• Add 50% rated voltage for 2 hours
• Add 75% rated voltage for 2 hours
• Add 100% rated voltage for 2 hours
