1.5 Use note
The design of the inverter allows it to operate in an industrial environment with electromagnetic interference.
Usually, if the quality is good, it can ensure the safety of inverter and trouble free operation, please install to
ensure the inverter can run reliably and effectively avoid the electromagnetic interference caused by the
following rules.
●Ensure that the grounding cable of all control devices are connected to the inverter as transducer with
short and thick, reliably connected to public places or public star connection grounding bus motor; please
contact the nearest ground, please do not put the shell of the motor is connected to the earthing terminal or
inverter control system protection.
●When the equipment is not grounded, the contact leakage occurs. Please connect the grounding end
of the inverter to the equipment shell and motor shell, and the single phase 220V converter N terminal must
be connected to zero line
●Conductors are preferably flat and multicore because they are less impedance at high frequencies
●The ends of the truncated cables should be as neat as possible to ensure that the segments are as
short as possible
●Control cable wiring should be far away from the power supply cables and the motor cable, use wire
slot alone, and must be in power cables and the motor cable when crossing each other should adopt 90
degrees vertical cross.
13
●The cabinet is installed to ensure the contactor with a surge suppressor. Or, there is a 'R-C' damping
circuit is connected to the coil of AC contactor, the use of varistor and corresponding coil voltage; the coil DC
contactor is connected with a "freewheeling diode" or coil device voltage corresponding to the type of
varistor; the output control relay in inverter contactor contactor occasions and frequent action, this is
especially important.
●The connection wire of the motor shall be shielded cable or armored cable, and the grounding end of
the shielding layer can be reliably grounded by the cable grounding card
●Install "input noise filter" can reduce the electromagnetic interference brought from the grid side of
other equipment, the input side noise filter "must be as close as possible to the inverter power input terminal,
at the same time, with the same inverter filter must be reliable grounding.
●Install "the output side filter can reduce noise" wireless interference from the motor and the inductive
interference, "the output side filter noise" must be as close as possible to the inverter output terminals, at the
same time, with the same inverter filter must be reliable grounding.
●Shielded cable or twisted pair shall be used whenever the control loop is connected
●Adding the "zero phase reactor" in the power line near the inverter input terminal, adding the "zero
phase reactor" in the motor line near the inverter output terminals, adding "zero phase reactor" in the control
line near the inverter control terminal, can effectively reduce the electromagnetic interference and the main
power cable connected inverter induction.
●Grounding, correct and reliable grounding are the basic conditions for the safe and reliable operation
of this product. In order to properly connect the converter to the ground, please read the following cautions
carefully
●To avoid electric shock, please use the dimensions specified in the electrical
equipment technical standard, and shorten the wiring length as much as possible, and
warning
the grounding resistance is below 10 Omega.Otherwise, the leakage current caused by
the inverter will lead to the unstable potential of the grounding terminal far from the
grounding point, which will lead to an electric shock accident
●Do not share the ground wire with the welder or power equipment that requires high
current / pulse current, otherwise it will cause abnormal operation of the inverter
●When using multiple inverters, do not loop the ground. Otherwise, the inverter will act
abnormally
●The motor must be grounded independently, and the motor casing can not be
Causion
connected to the ground terminal of the converter, nor can the same ground network be
shared with the control system

3.2 Description of Peripheral Devices for Main Circuit
The capacity of the circuit breaker shall be 1.5 ~ 2 time of the rated current of the inverter.
Circuit breaker
The time features of the circuit breaker shall fully consider the time features of the inverter
overload protection.
Because the inverter output is the high-frequency pulse, there will be high-frequency leakage
current. Special leakage circuit breaker shall be used when installing leakage circuit breaker
Leakage circuit
at the input end of the inverter.
breaker
It is suggested that B type leakage circuit breaker be used, and the leakage current value
shall be set as 300mA.
Frequent open and close of contactor will cause inverter failure, so the highest frequency for
the open and close of contactor shall not exceed 10 times/min.
Contactor
When braking resistor is used, to void the overtemperature damage of the braking resistor,
thermal protection relay with braking resistor overtemperature detection shall be installed to
disconnect the contactor at the contact control power side of the thermal protection relay.
1. The inverter power supply capacity is more than 600kVA or 10 times of the inverter capacity.
2. If there is switch type reactive-load compensation capacitor or load with silicon control at
the same power node, there will be high peak current flowing into input power circuit,
causing the damage of the rectifier components.
Input AC reactor
3. When the voltage unbalancedness of the three-phase power supply of the inverter
or DC reactor
exceeds 3%, the rectifier component will be damaged.
4. It is required that the input power factor of the inverter shall be higher than 90%.
When the above situations occur, install the AC reactor at the input end of the inverter or DC
reactor to the DC reactor terminal.
The noise input from the power end to the inverter and output from the inverter to the power
Input noise filter
end can be reduced.
Although the inverter has motor overload protection function, when one inverter drives two or
Thermal protection
more motors or multi-pole motors, to prevent the motor overtemperature failure, thermal
relay
protection relay shall be installed between the inverter and each motor, and the motor
overload protection parameter Pd.00 shall be set as “2” (motor protection disabled).
When the output end of the inverter is connected with noise filter, the conduction and
Output noise filter
radiation interference can be reduced.
When the cable connecting the inverter and the motor is longer than 100m, it is suggested to

install AC output reactor to suppress the high-frequency oscillation to avoid the damage to
motor insulation, large leakage current and frequent inverter protective action.

3.8 Attention for Main Circuit Wiring
3.8.1 Power Supply Wiring
It is forbidden to connect the power cable to the inverter output terminal, otherwise, the internal
components of the inverter will be damaged.
To facilitate the input side overcurrent protection and power failure maintenance, the inverter shall
connect to the power supply through the circuit breaker or leakage circuit breaker and contactor.
Please confirm that the power supply phases, rated voltage are consistent with that of the nameplate,
otherwise, the inverter may be damaged.
3.8.2 Motor Wiring
It is forbidden to short circuit or ground the inverter output terminal, otherwise the internal components of
the inverter will be damaged.
Avoid short circuit the output cable and the inverter enclosure, otherwise there exists the danger of
electric shock.
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.
When contactor is installed between the inverter and the motor, it is forbidden to switch on/off the
contactor during the running of the inverter, otherwise, there will be large current flowing into the inverter,
triggering the inverter protection action.
Length of cable between the inverter and motor
If the cable between the inverter and the motor is too long, the higher harmonic leakage current of the
output end will cause adverse impact on the inverter and the peripheral devices. It is suggested that when
the motor cable is longer than 100m, output AC reactor be installed. Refer to the following table for the
carrier frequency setting.
Length of cable between the
Less than 50m
Less than 100 m
More than 100m
inverter and motor
Carrier frequency (P2.30)
Less than 15kHz
Less than 10kHz
Less than 5kHz
3.8.3 Grounding Wiring
The inverter will produce leakage current. The higher the carrier frequency is, the larger the leakage
current will be. 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.
The grounding resistance shall be less than 10ohm. For the grounding wire diameter requirement, refer
to 3.3 lectotype of main circuit peripheral devices.
Do not share grounding wire with the welding machine and other power equipment.
25
In the applications with more than 2 inverters, keep the grounding wire from forming a loop.

Fig. 3−3 Grounding wiring
3.8.4 Countermeasures for Conduction and Radiation Interference
Inverter
Input filter
Filtering cable
Fig. 3-4 noise current legend
When the input noise filter is installed, the wire connecting the filter to the inverter input power end shall
be as short as possible.
The filter enclosure and mounting cabinet shall be reliably connected in large area to reduce the back
flow impedance of the noise current Ig.
The wire connecting the inverter and the motor shall be as short as possible. The motor cable adopts
4-core cable, with the grounding end grounded at the inverter side, the other end connected to the motor
enclosure. The motor cable shall be sleeved into the metal tube.
The input power wire and output motor wire shall be kept away from each other as long as possible.
The equipment and signal cables vulnerable to influence shall be kept far away from the inverter.
Key signal cables shall adopt shielding cable. It is suggested that the shielding layer shall be grounded
with 360-degree grounding method and sleeved into the metal tube. The signal cable shall be kept far
away from the inverter input wire and output motor wire. If the signal cable must cross the input wire and
output motor wire, they shall be kept orthogonal.
When analog voltage and current signals are adopted for remote frequency setting, twinning shielding
cable shall be used. The shielding layer shall be connected to the grounding terminal PE of the inverter,
and the signal cable shall be no longer than 50m.
The wires of the control circuit terminals RA/RB/RC and other control circuit terminals shall be separately
routed.
It is forbidden to short circuit the shielding layer and other signal cables or equipment.
When the inverter is connected to the inductive load equipment (e.g. electromagnetic contactor, relay
and solenoid valve), surge suppressor must be installed on the load equipment coil, as shown in Fig.3-5.
