Attention
Safety precautions
(1) Definition of safety information
Notice
Steps taken to ensure proper operation.
Danger
If you do not comply with the relevant requirements, it will cause serious personal
injury, or even death.
Warning
Failure to comply with the requirements may result in personal injury or equipment
damage.
(2) Safety notice
Unpacking check
Notice
1. Before unpacking, please check whether the outer package of the product is in good condition, and whether
there is damage, moisture, deformation, etc.
2. Before unpacking, please check whether the external model identification of the packing box is consistent with
that of the ordered model.
3. When unpacking, please check the surface of products and accessories for damage, corrosion, bruise, etc.
4. After unpacking, please check whether the product name plate label is consistent with the external model label.
5. After unpacking, check whether the internal accessories are complete, including operation panel and expansion
card.
Note: If any of the above five points appear during unpacking, please contact the local Xinje office or Xinje dealer
in time, and we will solve the problem for you as soon as possible.
Installation
Notice
1. When carrying, please hold the bottom of the machine.
If you only hold the panel, there is a risk that the main body will fall and hurt your feet.
2. Please install it on the plate of metal and other non combustible materials.
If it is installed on flammable materials, there is a risk of fire.
3. When more than two inverters are installed in the same control cabinet, please set the cooling fan and keep the
air temperature at the air inlet below 40 ℃.
Due to overheating, it can cause fire and other accidents.

2
Wiring
Notice
1. Please confirm whether the rated voltage of AC main circuit power supply is consistent with that of frequency
converter.
Danger of injury and fire.
2. Do not do voltage withstand test on the inverter.
Will cause damage to semiconductor components, etc.
3. Please connect the brake resistor or brake unit according to the wiring diagram.
There is a risk of fire.
4. Please use the screw driver with specified torque to fasten the terminal.
There is a risk of fire.
5. Do not connect the input power line to the output U, V and W terminals.
If the voltage is applied to the output terminal, the inverter will be damaged internally.
6. Do not connect the phase-shifting capacitor and LC / RC noise filter to the output circuit.
It will cause internal damage to the inverter.
7. Do not connect the electromagnetic switch and contactor to the output circuit.
When the frequency converter is running with load, the surge current generated by the action of electromagnetic
switch and electromagnetic contactor will cause the over-current protection circuit of the frequency converter to
act.
8. Do not remove the front panel cover.
May cause internal damage to the inverter.
Danger
1. Before wiring, please make sure that the input power has been cut off.
Danger of electric shock and fire.
2. Ask electrical engineering professionals to do wiring operation.
Danger of electric shock and fire.
3. The grounding terminal must be reliably grounded.
Danger of electric shock and fire.
4. After the emergency stop terminal is connected, be sure to check whether its action is effective.
There is a risk of injury. (the responsibility for wiring shall be borne by the user)
5. Do not touch the output terminal directly, do not connect the output terminal of the inverter with the cover, and
do not short circuit between the output terminals. There is danger of electric shock and short circuit.
6. After cutting off the AC power supply, before the indicator light of the AC motor driver goes out, it means that
there is still high voltage inside the AC motor driver, which is very dangerous. Please do not touch the internal
circuit and components.

Maintenance and inspection
Notice
1. The keyboard, control circuit board and driver circuit board are equipped with CMOS integrated circuits.
Please pay special attention when using.
If you touch the circuit board directly with your fingers, static induction may damage the integrated chip on the
circuit board.
2. Do not change the wiring or remove the terminal wiring during power on. Do not check the signal during
operation. It will damage the equipment.
Danger
1. Do not touch the terminal of the inverter, there is high voltage on the terminal.
Danger of electric shock.
2. Before power on, be sure to install the terminal cover. When removing the cover, be sure to disconnect the
power supply.
Danger of electric shock.
3. Non professional technicians are not allowed to carry out maintenance and inspection.
Danger of electric shock.

Precautions for use
Constant torque and low speed operation
When the inverter with ordinary motor runs at low speed for a long time, the motor life will be affected due to
the poor heat dissipation effect. If low speed constant torque long-term operation is needed, special frequency
conversion motor must be selected.
Confirmation of motor insulation
When using VH6 series frequency converter, please confirm the insulation of the motor before connecting the
motor, so as to avoid damaging the equipment. In addition, when the motor is in a bad environment, please
check the insulation of the motor regularly to ensure the safe operation of the system.
Negative torque load
For such occasions as lifting the load, there will often be negative torque, and the frequency converter will trip
due to over-current or over-voltage fault. At this time, the selection of braking resistance should be considered.
Mechanical resonance point of load device
In a certain output frequency range, the inverter may encounter the mechanical resonance point of the load
device, which must be avoided by setting the jump frequency.
Capacitors or varistors to improve power factor
As the output voltage of the frequency converter is pulse wave type, if the output side is installed with
capacitors to improve the power factor or varistors for lightning protection, it will cause the frequency converter
fault trip or device damage. Please remove it. In addition, it is recommended not to add air switch and contactor
and other switching devices on the output side.
The use of derating when setting the fundamental frequency
When the fundamental frequency is lower than the rated frequency, please pay attention to the derating of the
motor to avoid overheating and burning.
Operate at frequency above 50 Hz
If the frequency exceeds 50 Hz, in addition to considering the vibration and noise increase of the motor, it is
also necessary to ensure the speed range of the motor bearing and mechanical device, and make sure to check in
advance.
Electronic thermal protection value of motor
When selecting the suitable motor, the inverter can implement thermal protection for the motor. If the rated
capacity of motor and frequency converter does not match, the protection value must be adjusted or other
protection measures must be taken to ensure the safe operation of motor.
Altitude and derating
In the area with altitude more than 1000 meters, the heat dissipation effect of frequency converter becomes
worse due to the thin air, so it is necessary to reduce the rating.
About the protection level
The protection grade IP20 of VH6 series frequency converter is achieved when the status display unit or
keyboard is selected.
Notes on scrapping
When scrapping the inverter, please pay attention to:
When the electrolytic capacitors in the main circuit and printed circuit board are burned, they may explode.
Toxic gases are produced when plastic parts are burned. Please treat as industrial waste.
