Safety Precautions
Operation
Danger
Danger
Power supply can only be connected after the wiring is completed and the cover is
installed. It is forbidden to remove the cover in live condition; otherwise, there exists the
risk of electric shock.
When auto failure reset function or restart function is set, isolation measures shall be
taken for the mechanical equipment, otherwise, personal injury may be caused.
When the inverter is powered on, even when it is in the stop state, the terminals of the
inverter are still live. Do not touch the inverter terminals; otherwise electric shock may
be caused.
The failure and alarm signal can only be reset after the running command has been cut
off. Otherwise, personal injury may be caused.
Note
Note
Do not start or shut down the inverter by switching on or off the power supply, otherwise,
the inverter may be damaged.
Before operation, please confirm if the motor and equipment are in the allowable use
range, otherwise, the equipment may be damaged.
The heatsink and the braking resistor have high temperature. Please do not touch such
device; otherwise, you may be burnt.
When it is used on lifting equipment, mechanical contracting brake shall also be
equipped.
Please do not change the inverter parameter randomly. Most of the factory set
parameters of the inverter can meet the operating requirement, and the user only needs
to set some necessary parameters. Any random change of the parameter may cause
the damage of the mechanical equipment.
In the applications with industrial frequency and variable frequency switching, the two
contactors for controlling the industrial frequency and variable frequency switching shall
be interlocked.

on state, please do not touch the inverter terminals; otherwise, there
exists the risk of electric shock.
If cover is to be removed, the power supply must be disconnected first.
Wait for at least 10 minutes after power off or confirm that the CHARGE LED is off
before maintenance and inspection to prevent the harm caused by the residual voltage
of the main circuit electrolytic capacitor to persons.
The components shall be maintained, inspected or replaced by qualified electricians.
