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 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

- 2 -
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.
18. The company will not be responsible for any loss of property and personnel caused by
unauthorized modification of the inverter or failure to follow the procedures in this manual.

GP unification Model
description
Users check factory models through P0.00. P type is one lower power than G type.
E.g：If you need 11kw P type, 7.5kw G type could be selected as a replacement. Its input
current is the rated input current (20.5A) of 7.5kw G type, but its rated power is that of
11kw G type, and output current is the rated output current(25A) of 11kw G type.
Though inverter hardware of GP unification is different, there are some
optimization of software parameters for different load types .
P type model is only suitable for pump, fan etc light load models, can not work at the rated
current or more than the rated frequency for a long time.

Carrier
frequency
setting
For occasions requiring silent
operation, the carrier frequency can be
appropriately increased to meet the
requirements, but it will increase the
heat generation of the inverter.
When the inverter leaves the factory,
the manufacturer has set a reasonable
carrier frequency. Under normal
circumstances, the user does not need to
modify this parameter.

V/F frequency

When P0.13=2 (multi-point V/F curve),
users can use F0.17~F0.22 V/F curve.
The V/F curve is usually set according
to the load characteristics of the motor.
Note: V1<V2<V3, F1<F2<F3, the low
frequency voltage setting is too high
may cause the motor to overheat or
even burn, the inverter may be over
current stall or over current protection.

Starting DC braking current and time:
When the inverter starts, perform DC
braking according to the setDC braking
current before starting, and then start
the acceleration operation after the set
DC braking time before starting. If the
DC braking time is set to 0, the DC
braking is invalid. The greater the DC
braking current, the greater the braking
force.
