certain material loss.
This symbol indicates matters needing attention in operation or use.
This symbol prompts the user with some useful information.
The following two icons are supplementary descriptions of the above signs:
It means something that must not be done.
Indicates something that must be done.
1.2. Use range
This inverter is suitable for general industrial three-phase AC asynchronous motors.
● And in equipment (nuclear power control equipment, aerospace equipment, transportation equipment, life support
system, safety equipment, weapon system, etc.) which may threaten life or harm human body due to inverter failure or
working error, please consult our company in advance for special purpose.
● This product is manufactured under the strict supervision of the quality management system, but safety protection
measures must be taken to prevent the inverter from expanding the scope of the accident when it is used in important
equipment.
1.3 Installation Environment
● is installed indoors and in well-ventilated places, and should be installed vertically to ensure the best cooling effect.
additional ventilation devices may be required in horizontal installation.
● The environmental temperature should be within the range of-10 ~ 40℃. If the temperature exceeds 40℃, please
remove the upper cover. If the temperature exceeds 50℃, it needs external forced heat dissipation or derating. Users are
advised not to use the inverter in such a high temperature environment, because this will greatly reduce the service life of
the inverter.

● The environmental humidity is required to be lower than 90%, and there is no condensation of water droplets.
● it is installed in a place with vibration less than 0.5G to prevent falling damage. The inverter is not allowed to suffer
sudden impact.
● it is installed in an environment far away from electromagnetic fields and free of inflammable and explosive
substances.
1.4 Installation safety matters
● Do not work with wet hands.
● It is strictly forbidden to carry out wiring operations without completely disconnecting the power supply.
● When the inverter is powered on, please do not open the cover or carry out wiring operation, otherwise there is a
danger of electric shock.
● When wiring and inspection are carried out, it must be carried out 10 minutes after the power supply is turned off,
otherwise there is a danger of electric shock.
● Do not install inverters with damaged or missing components to avoid personal accidents and property losses.
● The main circuit terminal must be firmly connected with the cable, otherwise the inverter may be damaged due to
poor contact.
● For the sake of safety, the grounding terminals of inverters must be grounded reliably. To avoid the influence of
grounding common impedance interference, multiple inverters should be grounded by one-point grounding, as shown in
Figure 1-1.
Figure 1-1
● It is forbidden to connect the AC power supply to the output terminals U, V and W of the inverter, otherwise the
inverter will be damaged, as shown in Figure 1-2.
Figure 1-2
● When it is on the input power supply side of the inverter. Be sure to configure a fuse-free circuit breaker for circuit
protection to prevent the accident from expanding due to the failure of the inverter.

● The electromagnetic contactor should not be installed on the output side of the inverter, because the contactor will
turn on and off when the motor is running, which will produce operating overvoltage and cause damage to the inverter.
However, configuration is still necessary for the following three situations:
The frequency conversion governor used for energy-saving control, the system often works at rated speed, and in
order to realize economic operation, it is necessary to cut off the inverter.
Participate in important process flow, cant shut down for a long time, and need to switch between various control
systems to improve system reliability.
When one inverter controls multiple motors. Users should pay attention to the fact that the contactor must not act
when the inverter has output!
1.5 Use safety matters
● Do not operate with wet hands.
● For inverters with stored for more than one year, the voltage regulator should be used to gradually increase the
voltage to the rated value when powering on, otherwise there is danger of electric shock and explosion.
●Don’t touch the inside of the inverter after it is powered on, and don’t put bars or other objects into the inverter,
otherwise it will cause electric shock death or the inverter can’t work normally.
●Please do not open the face cover when the inverter is powered on, otherwise there is a danger of electric shock.
● Use the restart function after power failure with caution, otherwise it may cause personal injury or death.
●If it runs over 50Hz, it is necessary to ensure the speed range of motor bearings and mechanical devices in use.
●Mechanical devices requiring lubrication, such as reduction boxes and gears, should not run at low speed for a long
time, otherwise their service life will be shortened and even equipment will be damaged.
● When the ordinary motor runs at low frequency, it must be derated because of its poor heat dissipation effect. If it is a
constant torque load, it must adopt the forced heat dissipation mode of motor or adopt a special frequency conversion
motor.
● Please cut off the input power of the inverter when it is not used for a long time, so as to avoid the inverter being
damaged or even causing fire due to foreign matter entering or other reasons.
● Since the output voltage of the inverter is PWM pulse wave, please do not install capacitors or surge current
absorbers (such as piezoresistors) at its output end, otherwise the inverter will fail and trip, and even the power
components will be damaged. If installed, be sure to remove it. As shown in figure 1 -3.
Figure 1-3
● Before the motor is used for the first time or placed for a long time before reuse, the motor insulation shall be
checked and the measured insulation resistance shall be ensured to be no less than 5MΩ.
● If you need to use the inverter outside the allowable working voltage range, you need to configure a step-up or
step-down device for transformation processing.
● In the area where the altitude exceeds 1,000 meters, the heat dissipation effect of the inverter will deteriorate due to
the thin air, so it needs to be derated. Generally, it needs to be derated by about 10% for every 1000m increase.

● Places without corrosive gases and liquids;
● Places with less dust, oil and gas and metal dust;
● Places without vibration and easy to maintain and check;
● Places without electromagnetic noise interference;
3.3 Installation space and direction
● For the convenience of maintenance, enough space should be left around the inverter. As shown in the figure.
● In order to achieve good cooling effect, the inverter must be installed vertically and the air circulation should be
smooth.
●If the installation is not secure. After installing a flat plate under the base of the inverter, it is installed on a loose plane,
and the stress may cause damage to the main circuit parts, thus damaging the inverter;
● The wall of installation shall be made of incombustible materials such as iron plates.
● Multiple inverters are installed in the same cabinet. When installing from top to bottom, pay attention to the spacing,
and add a diversion baffle in the middle or install it in a staggered way.

4.4 Matters needing attention for Wiring
4.4.1 Main circuit wiring
●When wiring , please implement wiring in accordance with the provisions of electrical laws and regulations to ensure
safety.
● For power supply wiring, please use isolation wire or line pipe, and ground both ends of the isolation layer or line
pipe;
● Please install an air circuit breaker NPB between the power supply and the input terminals (R, S, T). (If using the
leakage circuit breaker, please use the circuit breaker with high frequency countermeasures).
● Please arrange the power line and control line separately, and do not place them in the same trunking.
● Do not connect the AC power supply to the inverter output terminals (U, V, W);
● The output wiring must not touch the metal part of the inverter housing, otherwise it may cause a short circuit to the
ground.
● Components such as phase-shifting capacitors, LC and RC noise filters cannot be used at the output end of inverter.
● The main circuit wiring of inverter must be far away from other control equipment.

● When the wiring between the inverter and the motor exceeds 50m (220V series) and 100m (380V class), high dv/dt
will be generated in the coil of the motor, which will damage the interlayer insulation of the motor. Please use the AC motor
dedicated to the inverter or install a reactor on the inverter side.
● When the distance between the inverter and the motor is long, please reduce the carrier frequency, because the
larger the carrier, the greater the leakage current of higher harmonic on the cable, which will have adverse effects on the
inverter and other equipment.
4.4.2 Control circuit wiring (signal line)
The signal line should not be placed in the same slot as the main circuit wiring, otherwise interference may occur.
Please use shielded wires for signal wires, and ground them at one end. The wire diameter is 0.5-2mm² 1 shielded wire is
recommended for the control line. Use the control terminals on the control keypadcorrectly as required.
4.4.3 Grounding wire
Please use the third grounding method (below 100Ω) to ground the grounding wire terminal E; Please use the
grounding wire according to the technical basic length and size of electrical equipment; Never share the grounding
electrode with large power equipment such as electric welding machine and power machinery, and the grounding wire
should be as far away from the power line of large power equipment as possible; Please use the grounding wiring mode of
multiple inverters in the following figure (a) to avoid the loop of (b) or (c).
● Grounding wiring must be as short as possible.
●Please properly ground the grounding terminal E, and never connect to the zero line.

4.5 Matters needing attention for specific application
4.5.1 Type selection
(1) Installation of reactor
When the inverter is connected to a large-capacity power transformer (above 600kVA) or the phase-advancing
capacitor is switched, the power input circuit will produce excessive peak current, which may damage the components of
the converter. To prevent this, please install DC reactor or AC reactor. This also helps to improve the power factor on the
power supply side. In addition, when thyristor converters such as DC drivers are connected to the same power supply
system, DC reactors or AC reactors must be set regardless of power supply conditions.
Inverter Capacity (KVA)
Installation conditions of reactor
(2) Inverter capacity
When running a special motor, please make sure that the rated current of the motor is not higher than the rated output
current of the inverter. In addition, when running multiple induction motors in parallel with a inverter, the capacity of the
inverter should be selected so that 1.1 times of the total rated current of the motors is less than the rated output current of
the inverter.
(3) Starting torque
The starting and accelerating characteristics of the motor driven by inverter are limited by the overload rated current of
the combined inverter. Compared with the starting of general commercial power supply, the torque characteristic is smaller.
If a large starting torque is required, please increase the capacity of the inverter by one level or increase the capacity of the
motor and inverter at the same time.
(4) Emergency stop
Although the protection function will act and the output will stop when the inverter fails, the motor cannot be stopped
suddenly at this time. Therefore, please set mechanical stop and hold structure on the mechanical equipment that needs
emergency stop.

(5) Special options
Terminals PB(+) and P1(+) are terminals for connecting with special optional items. Do not connect machines other
than special options.
(6) Precautions related to reciprocating load
When the inverter is used for reciprocating loads (cranes, elevators, punching machines, washing machines, etc.), if
150% or more of the current flows repeatedly, the service life of IGBT inside the inverter will be shortened due to thermal
fatigue. As a general standard, when the carrier frequency is 4kHz and the peak current is 150%, the starting/stopping
times are about 8 million times.
Especially when low noise is not required, please reduce the carrier frequency. In addition, please reduce the peak
current during reciprocating to less than 150% by reducing the load, prolonging the acceleration and deceleration time, or
increasing the capacity of the inverter by one level (during the trial run for these purposes, please confirm the peak current
during reciprocating and adjust it as needed). In addition, when used in cranes, it is suggested to make the following
choices to ensure the motor torque and reduce the current of the inverter, because the starting/stopping action during JOG
is fast. · The capacity of the inverter should ensure that its peak current is lower than 150%. The capacity of inverter should
be more than 1 level larger than that of motor.
4.5.2 Matters needing attention in motor use
(1) It is used for existing standard motors
Low speed domain
Compared with the standard motor driven by commercial power supply, the loss caused by using inverter will increase
somewhat. In the low speed range, the cooling effect will deteriorate and the temperature of the motor will increase.
Therefore, in the low speed range, please reduce the load torque of motor. The allowable load characteristics of our
standard motor are shown in the figure. In addition, when 100% continuous torque is required in low speed range, please
discuss whether to use the special motor for inverter.
Frequency (Hz)
Allowable load characteristics of our standard motor
(2) Matters needing attention for special motors
The rated current of the pole-changing motor is different from that of the standard motor. Please confirm the maximum
current of the motor and select the corresponding inverter. Be sure to switch the number of poles after the motor stops. If
switching is performed during rotation, the regeneration overvoltage or overcurrent protection circuit will act and the free
running of the motor will stop.
Motor with brake
When using inverter to drive motor with brake, if the brake circuit is directly connected to the output side of inverter, the
brake will not open due to the low voltage during starting. Please use the motor with brake with independent brake power
supply, and connect the brake power supply to the power supply side of the inverter. In general, when using a motor with a
brake, the noise in the low speed range may become larger.
(3) Power transmission structure (reducer, belt, chain, etc.)
When the gearbox, gearbox and reducer with oil lubrication mode are used in the power transmission system, the oil
lubrication effect will become worse if they only run continuously in the low speed range, so please pay attention. In
addition, when running at high speed above 60Hz, problems such as noise of power transmission structure, service life,
strength caused by centrifugal force, etc. will occur, so please pay full attention to it.
