1. Please confirm whether the rated voltage of AC main circuit power supply is consistent with that of frequency
converter.
Danger of injury and fire.
2. Do not do voltage withstand test on the inverter.
Will cause damage to semiconductor components, etc.
3. Please connect the brake resistor or brake unit according to the wiring diagram.
There is a risk of fire.
4. Please use the screw driver with specified torque to fasten the terminal.
There is a risk of fire.
5. Do not connect the input power line to the output U, V and W terminals.
If the voltage is applied to the output terminal, the inverter will be damaged internally.
6. Do not connect the phase-shifting capacitor and LC / RC noise filter to the output circuit.
It will cause internal damage to the inverter.
7. Do not connect the electromagnetic switch and contactor to the output circuit.
When the frequency converter is running with load, the surge current generated by the action of electromagnetic
switch and electromagnetic contactor will cause the over-current protection circuit of the frequency converter to
act.
8. Do not remove the front panel cover.
May cause internal damage to the inverter.
1. Before wiring, please make sure that the input power has been cut off.
Danger of electric shock and fire.
2. Ask electrical engineering professionals to do wiring operation.
Danger of electric shock and fire.
3. The grounding terminal must be reliably grounded.
Danger of electric shock and fire.
4. After the emergency stop terminal is connected, be sure to check whether its action is effective.
There is a risk of injury. (the responsibility for wiring shall be borne by the user)
5. Do not touch the output terminal directly, do not connect the output terminal of the inverter with the cover, and
do not short circuit between the output terminals. There is danger of electric shock and short circuit.
6. After cutting off the AC power supply, before the indicator light of the AC motor driver goes out, it means that
there is still high voltage inside the AC motor driver, which is very dangerous. Please do not touch the internal
circuit and components.
