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
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. The
inverter with single/three-phase 230V AC as its input voltage can apply Single phase 230V AC/2A
power surge (L+ to R and N to S or T). 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.
Change electrolytic capacitors if the working hours of electrolytic capacitors in the inverter are
above 35000. Please contact with the local ASTOR offices or dial our service hotline 12 424-00-88
for detailed operation.
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. Using the information given in this
chapter, most alarm and fault cause can be identified and corrected. If not, contact with the ASTOR
office.
6.2.2 How to reset
The inverter can be reset by pressing the keypad key STOP/RST, through digital input, or by
