1. Увод
This manual provides essential information for the safe and efficient operation of your MENDUNER AT1-4000X Variable Frequency Drive (VFD). Please read this manual thoroughly before installation, operation, or maintenance to ensure proper usage and prevent damage or injury.
The AT1-4000X VFD is designed to control the speed of three-phase AC motors. It features a unique control method to achieve high torque, high precision, and a wide range of speed regulation, offering high performance. It also provides good anti-trip performance and the ability to adapt to strong power interference, temperature, humidity, and dust, significantly improving stability. By optimizing PWM control technology and electromagnetic compatibility, it meets user requirements for low noise and low electromagnetic interference. It offers fast start and stop response and high torque at low speeds.
2. Мере предострожности
Failure to follow these safety instructions may result in electric shock, fire, or serious injury. Always observe all warnings and instructions.
- Before wiring, ensure the power supply is completely disconnected.
- Wiring should only be performed by a qualified professional engineer.
- Do not install the inverter on flammable or explosive materials.
- Уземљење инвертора мора бити правилно и безбедно уземљено.
- Do not touch the inverter terminals immediately after power-off, as residual voltagе можда још увек постоји.
- Only professional personnel should perform wiring and internal maintenance due to high voltage inside the inverter, which can cause electric shock.
