charging. The small capacitor
power (2A is enough) can be used because the capacitor nearly does not need current when
charging.
The operation method
resistors (LEDs):
The charging time is at least 60 minutes if charge the DC bus capacitor directly through supply
power. This operation is available on normal temperature and no-load condition and the resistor
should be serially connected in the 3-phase circuits of the power supply(the distance between
resistors of each phase
≥5.5mm):
380V drive device: 1k/100W resistor. LED of 100W can be used when the power voltage is no
more than 380V. But if used, the light may be off or weak during charging.

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
