noise filter, which will lead to inverter fault or component damage.
9. When wiring change is required while power is on or inverter is running, inverter operation
must be stopped then wait for over 10 minutes after power is cut off. Check the voltage by
multi-meter then make the wiring change. There is still dangerous high voltage on capacitor
within a period after power is cut.
10. Ground terminal must be well grounded.
▲Since there is leakage current in inverter, in order to avoid electric shock, inverter and
motor must be grounded.
▲Use independent terminal for inverter grounding. DO NOT just use screw on shell or
chassis instead.
▲ It is recommended to adopt thick cable with demanded diameter no smaller then in the
attached form. Grounding wire should be near inverter, and ground wire be as short as
possible.
▲ When the motor is grounded on inverter side, please use one core of the four-core cable
to ground, with the same size to input wire.
