Cautions

Dangers

1. Untrained and qualified personnel working on the device/system of the controller or failing to observe the relevant regulations in the "Dangers" may cause serious personal injury or major property damage. Only qualified professionals who have been trained in the design, installation, commissioning, and operation of the equipment are allowed to work on the devices/systems of this equipment.

2. The input power cable is only allowed to be permanently tightly connected, and the equipment must be reliably grounded.

3. Even if the controller is not in operation, the following terminals may still carry dangerous voltages.

-Power terminals R, S, T, (+), (-)

-Terminal U, V, W connected to the motor

4. After the power switch is turned off, you must wait for 5 minutes to allow the controller to discharge before it is allowed to start installation.

5. The minimum cross-sectional area of the grounding conductor must be equal to or greater than the cross-sectional area of the power supply cable.


Warnings

1. Lift the cabinet by supporting the base, do not grab the panel and lift when moving the controller, otherwise the main unit may fall, which may cause personal injury.

2. Install the controller on flame-retardant materials (such as metal), otherwise it may cause a fire.

3. If more than two controllers are installed in a cabinet, a cooling fan should be installed, and the air temperature should be lower than45°C, otherwise overheating may cause fire or damage to the device.


Troubleshooting

The following fault conditions may be encountered during the use of the controller, please refer to the following methods for simple fault analysis:

No display after power-on:

1. Use a multimeter to check whether the input power of the controller is consistent with the rated voltage of the controller. If there is a problem with the power supply, please check and eliminate it.

2. Check whether the CHARGE lamp is on. If this light is on, the fault may be in the switching power supply. Please seek service.

After power on, the power air switch trips:

1. Check whether there is a grounding or short circuit between the input power

supplies and eliminate the problem.

2. Check whether the rectifier bridge has been broken down, if it is damaged, seek service.

The motor does not rotate after the controller is running

1. Check whether there is a balanced three-phase output among U, V, and W. If there is, the motor circuit or itself is damaged, or the motor is blocked due to mechanical reasons. Please exclude.

2. There is output but the three phases are not balanced. It may be because the

controller driver board or output module is damaged, please seek service.

3. If there is no output voltage, the drive board or output module may be damaged, please seek service.

Power on the controller shows normal, after running, the power air switch tripped:

1. Check whether there is a short circuit between the output modules. If yes, please seek service.

2. Check whether there is a short circuit or grounding between the motor leads. If so, please exclude it.

3. If the trip occurs occasionally and the distance between the motor and the controller is relatively long, consider adding an output AC reactor.


After-sales service

1. The warranty is limited to the inverter itself. Within 12 months from the date of purchase, the inverter will provide free maintenance services if the product is damaged due to malfunctions caused by the product itself within 12 months from the date of purchase.

2. During the warranty period, if something happens, our company will charge a certain amount of maintenance fee depending on the situation.

A. Failure to strictly follow the "Instruction Manual" or exceed the standard requirements in an environment that does not meet the requirements of the "Instruction Manual".

B. Failure caused by self-repair or modification without permission.

C. Faults caused when the inverter is used for abnormal functions.

D. The inverter is damaged due to incorrect wiring.

E. Damage caused by improper storage, fall or other external factors after purchase.

F. Failures caused by natural disasters such as abnormal voltage, lightning, fire, water mist, metal dust, gas corrosion, earthquakes, storms, or disaster-related causes.

G. Tear off the product identification (such as nameplate, etc.) without authorization; the serial number of the body does not match the warranty card.

3. If you have any questions, please contact the agent or contact our company directly.

4. For machines beyond the warranty period, our company will also provide lifetime paid maintenance services.
