Precautions
●Motor Insulation Inspection
Motor in use for the first time, placed a long time before re-use and periodic
inspection should be done, the motor insulation should be checked, to prevent the
motor winding insulation failure and damage to the inverter. To motor insulation check
connection separate from the inverter, 500V megger is recommended, should ensure
that the measured insulation resistance of not less than 5MΩ.
●Motor Thermal Protection
If the rated capacity of the motor Yes not match those of the inverter, especially
when the rated power of the inverter is higher than the rated power of the motor, be
sure to adjust the inverter motor protection parameter values , or thermal relay shall be
mounted for motor protection.
●Running with Frequency higher than Power Frequency
This inverter can provide output frequency from 0Hz to 3200Hz. If the customer is
required to run 50Hz above, consider the mechanical endurance of the device.
●Vibration of Mechanical Device
The inverter may encounter the mechanical resonance point at certain output
frequencies, which can be avoided by setting the skip frequency parameters in the
inverter.
●Motor Heat and Noise
Since the output voltage of inverter is PWM wave and contains certain harmonics,
the temperature rise, noise and vibration of the motor comparing with the power
frequency will be increased slightly.
●Use with the voltage different with the rated voltage
If the HV610C series inverter is used outside the allowable working voltage range
as specified in this manual, it is easily lead to the inverter devices damage. If needed,
use the corresponding boost or lower voltage transformer processing.
●The output side with the pressure-sensitive devices or to improve the power factor
capacitor
Since the inverter output is PWM wave, the output side if installed with capacitors
to improve the power factor or lightning varistors. Easily lead to the inverter
instantaneous overcurrent or even damage the drive, do not use.
●Switching Devices like Contactors Used at the Input and Output terminal
If a contactor is installed between the power supply and the input terminal of the
inverter, it is not allowed to use the contactor to control the startup/stop of the inverter.
Necessarily need to use the contactor control inverter start and stop of not less than an
hour. Frequent charge and discharge will reduce the service life of the capacitor inside
the inverter. If switching devices like contactor are installed between the output terminal
and the motor, should ensure that the inverter output off operation, otherwise easily lead
to the inverter module damage.

●Change Three-phase Input to Two-phase Input
It is not allowed to change the HV610C series three-phase inverter into two-phase.
Otherwise, it may cause fault or damage to the inverter. This operation must be handed
under HNC technical guidance.
●Lightning Surge Protection
The series inverter has lightning over current protection device, and has certain
self-protection ability against the lightning. In applications where lightning occurs
frequently, the user shall install additional protection devices in front of the inverter.
●Altitude and Derating Use
Altitude of over 1000m of the region, the heat sink’s cooling effect of the inverter
may turn poorer due to the thin air. Therefore, it needs to derate the inverter for use.
This case please contact our technical advice.
●Some Special Use
If the user needs to use the inverter with the methods other than the recommended
wiring diagram in this manual, such as DC bus, please consult our company.
●Cautions of Inverter scrapped
The electrolytic capacitors on the main circuit and the PCB may explode when they
are burnt. Emission of toxic gas may be generated when the plastic parts are burnt.
Processed as industrial waste.
●Adaptable Motor
1) The standard adaptable motor is four-pole squirrel-cage asynchronous induction
motor or permanent magnetic synchronous motor. If such motor is not available, be
sure to select adaptable motors in according to the rated current of the motor.
2) The cooling fan and the rotor shaft of the non-frequency-conversion motor adopt
coaxial connection. When the rotating speed is reduced, the heat sink cooling effect will
be reduced. Therefore, overheating occasions should be retrofitted with a strong
exhaust fan or replace the variable frequency motor.
3) Since the inverter has built-in standard parameters of the adaptable motors, it is
necessary to perform motor parameter identification or modify the default values so as
to comply with the actual values as much as possible, or it may affect the performance
and protective properties.
4)Since short circuit cable or internal circuit of motor may cause alarm,or even machine
explosion,please do insulation and short circuit test before the initial use as well as daily
maintenance.Note ：be sure to do this test, inverter and tested parts must be all
separated!

2) Try not set parallel arrangement for inverter input/output power line and weak
electric signal lines, set vertical arrangement if possible.
3) The inverter output power line is recommended to use shielded cable, or steel
shielded power line, and shielding layer should be reliable grounded. Twisted
pair shielded control cable is recommended for wiring of interference device.
4) If the distance between the inverter and the motor exceeds 100 meters,
output filter or reactor shall be installed.
Input filter installation EMC guidance：
1) Note ：The filters should strictly be used according to the rated value. As filter
belongs to class I appliances, filter metal shell ground shold be large area well
connected to installation cabinet metal ground, and good conductive continuity
is required. Otherwise there will be risk of electric shock and serious impact on
the EMC effect.
2) EMC test proves, filter and PE end must be connected to the same public
ground, otherwise it will seriously affect the EMC effect.
3) Filter should be installed as close as possible to the inverter power supply input.

Auto voltage regulation
(AVR)
It can keep constant output voltage automatically in case of change of
network voltage.
Over-voltage/current stall
control
It can limit the running voltage/current automatically and prevent
frequent over-voltage/current tripping during the running process
Quick current limit
Minimize the over-current fault,protect normal operation of the inverter
Torque limit & control
"Excavators" characteristics,automatically limit torque during
operation,prevent frequent over-current trip;
Closed loop vector mode can realize the torque control.
Personalized
Instantaneous stop
non-stop
When instantaneous power off,voltage reduction is compensated
through load feedback energy,which could make inverter keep running
in a short period of time.
Rapid current limit
To avoid inverter frequent over-current fault.
