please contact the factory previously.
1.2 Safety Precautions
Description of safety marks:
Danger: The misuse may cause fire, severe injury, even death.
Note: The misuse may cause medium or minor injury and equipment damage.
Use
DangerDanger
This series of inverter is used to control the variable speed operation of three-phase
motor and cannot be used for single-phase motor or other applications. Otherwise,
inverter failure or fire may be caused.
This series of inverter cannot be simply used in the applications directly related to the
human safety, such as the medical equipment.
This series of inverter is produced under strict quality management system. If the
inverter failure may cause severe accident or loss, safety measures, such as
redundancy or bypass, shall be taken.
Goods Arrival Inspection
NoteNote
If the inverter is found to be damaged or lack parts, the inverter cannot be installed.
Otherwise, accident may be caused.
Installation
NoteNote
When handling and installing the product, please hold the product bottom. Do not hold
the enclosure only. Otherwise, your feet may be injured and the inverter may be
damaged because of dropping.
The inverter shall be mounted on the fire retardant surface, such as metal, and kept far
away from the inflammables and heat source.
Keep the drilling scraps from falling into the inside of the inverter during the installation;
otherwise, inverter failure may be caused.
When the inverter is installed inside the cabinet, the electricity control cabinet shall be
equipped with fan and ventilation port. And ducts for radiation shall be constructed in
the cabinet.

Wiring
DangerDanger
The wiring must be conducted by qualified electricians. Otherwise, there exists the risk
of electric shock or inverter damage.
Before wiring, confirm that the power supply is disconnected. Otherwise, there exists the
risk of electric shock or fire.
The grounding terminal PE must be reliably grounded, otherwise, the inverter enclosure
may become live.
Please do not touch the main circuit terminal. The wires of the inverter main circuit
terminals must not contact the enclosure. Otherwise, there exists the risk of electric
shock.
The connecting terminals for the braking resistor are ⊕2/B1 and B2. Please do not
connect terminals other than these two. Otherwise, fire may be caused.
The leakage current of the inverter system is more than 3.5mA, and the specific value of
the leakage current is determined by the use conditions. To ensure the safety, the
inverter and the motor must be grounded.
NoteNote
The three-phase power supply cannot connect to output terminals U/T1, V/T2 and
W/T3, otherwise, the inverter will be damaged.
It is forbidden to connect the output terminal of the inverter to the capacitor or LC/RC
noise filter with phase lead, otherwise, the internal components of the inverter may be
damaged.
Please confirm that the power supply phases, rated voltage are consistent with that of
the nameplate, otherwise, the inverter may be damaged.
Do not perform dielectric strength test on the inverter, otherwise, the inverter may be
damaged.
The wires of the main circuit terminals and the wires of the control circuit terminals shall
be laid separately or in a square-crossing mode, otherwise, the control signal may be
interfered.
The wires of the main circuit terminals shall adopt lugs with insulating sleeves.
The inverter input and output cables with proper sectional area shall be selected
according to the inverter power.
When the length of the cables between the inverter and the motor is more than 100m, it
is suggested to use output reactor to avoid the inverter failure caused by the overcurrent
of the distribution capacitor.
The inverter which equipped with DC reactor must connect with DC reactor between the
terminal of ○
+1、○ +2, otherwise the inverter will not display after power on.

Operation
DangerDanger
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.
NoteNote
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.
Maintenance, Inspection
DangerDanger
In the power-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.

NoteNote
The circuit boards have large scale CMOS IC. Please do not touch the board to avoid
the circuit board damage caused by electro static.
Others
DangerDanger
It is forbidden to modify the inverter unauthorizedly; otherwise, personal injury may be
caused.
