Foreword
Thank you for using our company's inverter. Before using it, you must read this instruction manual carefully. Please use
it after you are familiar with the precautions of this product.
Installation Environment：
1. Installed indoors and in a well-ventilated place, generally should be installed vertically to ensure the best cooling
effect.
2. The ambient temperature is required to be in the range of -10~45℃.
3. The ambient humidity is required to be less than 90%, without water droplets condensing.
4. Install in a place with vibration less than 0.5G to prevent falling damage. The inverter is not allowed to suffer
sudden impact.
5. Install in an environment away from magnetic fields and free of flammable and explosive substances.
6. Make sure to install the inverter on fireproof materials (such as metal) to prevent fire.
7. Make sure that no foreign objects enter the inverter to prevent circuit shortcuts from burning down the inverter.

Safety Precautions
1. Before wiring, please confirm whether the input power is in the power off state.
2. It is strictly forbidden to operate with wet hands during wiring operation, and professional electrical engineering
personnel are required.
3. The main circuit terminal and the cable must be firmly connected, otherwise the inverter may be damaged due to
poor contact.
4. For safety reasons, the ground terminal of the inverter must be reliably grounded.
5. It is strictly forbidden to connect the AC 220V or 380V power supply to the terminals other than TA and TC in
the control terminal.
6. It is strictly forbidden to connect the AC power supply to the output U, V, W terminals of the inverter.
7. On the input power supply side of the inverter, be sure to configure a fuseless circuit breaker for circuit protection
or a circuit breaker with leakage protection to prevent the accident caused by the inverter from expanding.
8. Please confirm whether the voltage of the AC main circuit power supply is consistent with the rated voltage of the
inverter.
9. Do not intervene the contactor in the output circuit. If necessary, please consult our company or relevant qualified

VTS2000 Series frequency inverter

personnel in advance.
10. When the inverter is powered on, do not open the cover or perform wiring work.
11. Do not touch the inside of the inverter after power-on, and do not put conductive rods or other objects into the
inverter.
12. .For inverters that have been stored for more than half a year, a charging experiment should be conducted before
use to restore the characteristics of the filter capacitor of the inverter main circuit. When charging, the voltage
regulator should be used to gradually increase the voltage to the rated value. Within 1~2 hours, otherwise there is
a risk of electric shock or explosion.
13. Since the output voltage of the inverter is a PWM pulse wave, please do not install capacitors or inrush current
absorbers at its output. If it has been installed, be sure to remove it.
14. It is strictly forbidden to use contactors and other switching devices on the input side of the inverter to directly
start and stop frequently.
15. Derating is required for areas with an altitude of more than 1000 meters. -Generally, the derating is about 10%
every 1000 meters.。
16. If there are abnormal phenomena such as smoke, odor, strange noise, etc. in the inverter, please immediately cut
off the power and carry out maintenance or call the agent for service.
17. When carrying out inspection and maintenance, the main circuit power should be cut off first.
