EM730 User Manual

User Manual of EM730/EM730E Series Inverter Preface Thank you for choosing SINEE’s EM730/EM730E series inverter. Document No.: 31010183 Release time: June 2020 Version: 100 The EM730/EM730E series inverter is a high-reliable and small-sized universal inverter launched by SINEE. EM730 supports three-phase AC asynchronous motors, while EM730E supports permanent magnet synchronous motors. They support a variety of drive control technologies, such as the vector VF (VVF) control and speed sensorless vector control (SVC); speed output and torque output; and Wi-Fi access and background software debugging. Features of the EM730/EM730E series inverter:

 Support debugging by the mobile phone APP or monitoring of the inverter status;  Support Wi-Fi module or serial port access;  Rich and convenient PC background software functions;  No need for derating at the ambient temperature of 50 ℃ ;  Support “one-key shuttle” for fast and accurate speed adjustment;  Perfect protections: Protections against the short circuit, overcurrent, overvoltage, overload, overheating, etc. Before using the EM730/EM730E series inverter, please read this manual carefully and keep it properly. While connecting the inverter to motor for the first time, please select the motor type (asynchronous or synchronous) correctly and set the motor nameplate parameters:

rated power, rated voltage, rated current, rated frequency, rated speed, motor connection, rated power factor, etc. Since we are committed to continuously improving our products and product data, the data provided by us may be modified without prior notice.

User Manual of EM730/EM730E Series Inverter Safety precautions Safety definition: Safety precautions are divided into the following two categories in this manual: Danger: The dangers caused by nonconforming operations may include serious injuries and even deaths. Warning: The danger caused by nonconforming operations, including moderate or minor injuries and equipment damage. During the installation, commissioning and maintenance, please read this chapter carefully, and follow the safety precautions herein. Our company will not be liable for any injury or loss arising from nonconforming operations. Precautions Before installation: Danger 1.

Do not install the product in the case of water in the package or missing or damaged components found in unpacking! 2. Do not install the product in the case of inconsistency between the actual product name and identification on the outer package. Warning 1. Handle the controller with care; otherwise, it may be damaged! 2. Never use the inverter damaged or with some parts missing; otherwise, injuries may be caused! 3. Do not touch the components of the control system with your hands; otherwise, there is a danger of static damage! During installation: Danger 1. Please install the inverter on a metal retardant object (e.g. metal) and keep it away 2

User Manual of EM730/EM730E Series Inverter from combustibles; otherwise, a fire may be caused! 2. Do not loosen the fixing bolts of components, especially those with red marks! Warning 1. Never make wire connectors or screws fall into the inverter; otherwise, the inverter may be damaged! 2. Install the inverter in a place with little vibration and exposure to direct sunlight. 3. When the inverter is installed a relatively closed cabinet or space, pay attention to the installation gap to ensure the effects of heat dissipation. During wiring: Danger 1.

Follow the instructions in this manual, and appoint professional and electrical engineering personnel to complete wiring; otherwise, unexpected dangers may be caused! 2. The inverter and power supply must be separated by a circuit breaker (recommendation: greater than or equal to and closest to twice the rated current); otherwise, a fire may be caused! 3. Before wiring, make sure that the power supply is in the zero energy status; otherwise, electric shock may be caused! 4. Never connect the input power supply to the output terminals (U, V, W) of the inverter. Pay attention to the marks of wiring terminals, and connect wires correctly! Otherwise, the inverter may be damaged! 5.

Make the inverter grounded correctly and reliably according to the standards; otherwise, electric shock and fire may be caused! Warning 1. Make sure that the lines meet the EMC requirements and local safety standards. For wire diameters, refer to the recommendations. Otherwise, an accident may occur! 2. Never connect the braking resistor directly between the DC bus and terminal. Otherwise, a fire may be caused! 3. Tighten the terminals with a screwdriver of specified torque; otherwise, there is a risk of fire. 4. Never connect the phase-shifting capacitor and LC/RC noise filter to the output circuit. 5.

Do not connect the electromagnetic switch and electromagnetic contactor to the output circuit. Otherwise, the overcurrent protection circuit of the inverter will be enabled. In severe cases, the inverter may be subject to internal damage. 6. Do not dismantle the connecting cable inside the inverter; otherwise, internal damage may be caused to the inverter. 3

User Manual of EM730/EM730E Series Inverter Before power-on: Danger 1. Make sure that the voltage level of the input power supply is consistent with the rated voltage of the inverter; and the input terminals (R, S, T) and output terminals (U, V, W) of the power supply are connected correctly. Check whether there is short circuit in the peripheral circuits connected to the inverter and whether all connecting lines are tightened; otherwise, the inverter may be damaged! 2. The withstand voltage test has been performed to all parts of the inverter, so it is not necessary to carry it out again. Otherwise, an accident may be caused! Warning 1.

The inverter must not be powered on until it is properly covered; otherwise, electric shock may be caused! 2. The wiring of all peripheral accessories must be in line with the instructions in this manual. All wires should be connected correctly according to the circuit connections in this manual. Otherwise, an accident may occur! After power-on: Danger 1. Never touch the inverter and surrounding circuits with wet hands; otherwise, electric shock may occur! 2. If the indicator is not ON and the keyboard has no response after power-on, immediately turn off the power supply.

Never touch the inverter terminals (R, S, T) and the terminals on the terminal block with your hands or screwdriver; otherwise, electric shock may be caused. Upon turning off the power supply, contact our customer service personnel. 3. At the beginning of power-on, the inverter automatically performs a safety test to external strong current circuits. Do not touch the inverter terminals (U, V, W) or motor terminals; otherwise, electric shock may be caused! 4. Do not disassemble any parts of the inverter while it is powered on. Warning 1. When parameter identification is required, please pay attention to the danger of injury during motor rotation; otherwise, an accident may occur! 2.

Do not change the parameters set by the inverter manufacturer without permission; otherwise, the inverter may be damaged! 4
