During Installation：

A90 series Inverter User Guide Safety Information In this guide, there are two types of safety information. Danger ： The label indicates that a failure to follow instructions can result in serious injury or even death. Caution ： The label indicates that a failure to follow instructions can result in moderate or slight injury and device damage. Please read this chapter carefully before system installation, debugging and maintenance and always follow the safety precautions below during operation. SINEE will not undertake any damage or loss caused by a failure to follow the instructions. Safety Precautions Before Installation: Danger 1.

Do not install inverter if its package is wetted or any its component is missing or broken. 2. Do not install inverter if the label information on its package is not identical to that on inverter. Caution 1.Open the wooden box, please bring gloves, do not hand contact the wooden box on the sealed iron, or the risk of injury! 2.when handling the inverter, be sure to grasp the bottom of the inverter. If you hold the front cover, the inverter body may fall, there is the risk of being injured! 3.Be careful when carrying or transporting inverter so as to avoid damage! 4.Do not use inverter if it is damaged or any component is missing so as to avoid injury!

5.Do not touch the parts of control system with bare hands so as to avoid ESD! 6.the inverter has been Dielectric Withstand Voltage Test in the factory, do not carry on the Dielectric Withstand Voltage Test of the inverter, otherwise there is danger of damage to the inverter! During Installation ： Danger 1.Installation base shall be metal or other non-flammable material so as to prevent fire risk. 2.Do not unscrew fixing bolts, especially bolts with red mark. Caution 1. Can not be installed in the inverter with conductive dust, corrosive gases, salt spray, oil, condensation, vibration or direct sunlight occasions!

2.Ensure that no cable strips or screws are dropped into inverter so as to avoid damage to inverter. 3.Consider the installation space for cooling purpose when inverter is installed in a closed cabinet or space. 2

Before Power-on:

A90 series Inverter User Guide Wiring ： Danger 1.Wiring must be performed by authorized and qualified personnel so as to avoid unexpected accidents. 2.Between the inverter and the power supply must be separated from the circuit breaker (recommended to use greater or equal to and the nearest 2 times the rated current specifications), or it may fire! 3.Please confirm the power before the line is disconnected (zero energy) state, do not live for wiring work, or there is the risk of electric shock! 4.Never connect input power supply cable to output terminals (U, V ,W)of inverter. Pay attention to terminal symbols and connect to the terminals correctly.

Otherwise it will cause damage to the inverter, and even cause a fire! 5. Please follow the standard on the inverter for the correct and reliable grounding, otherwise there will be the risk of electric shock! Caution 1.Connect the inverter output terminals U, V, and W to the motor input terminals U, V and W, respectively. Phase sequence inconsistency can cause the motor to reverse. 2.Be sure that wiring meets EMC requirements and local safety standards. Cable should be in recommended sizes so as to prevent accident risk. 3.Must not be directly connected brake resistor to DC bus terminals + and – so as to prevent fire risk.will cause a fire!

4.Tighten terminals with a screwdriver of specified torque so as to prevent fire risk. 5.Do not connect a phase-shifting capacitor or an LC/RC noise filter to output circuits. 6.Do not connect the electromagnetic switch, electromagnetic contactor to the output circuit, otherwise the inverter over-current protection circuit action, serious, will lead to internal damage to the inverter. 7.Do not disconnect internal cable of inverter, or else this can possibly damage the internal parts of inverter. Before Power-on: 1.Please confirm whether the input power supply voltage level and inverter rated voltage level, otherwise it will lead to equipment damage or cause a fire; 2.

Confirm the power input terminal (R, S, T), and the output terminals (U, V, W) on the connection position is correct; 3. Pay attention to check with the inverter connected to the external circuit is short-circuit phenomenon, the connection line is fastened, otherwise it will cause the inverter damage! Danger Caution 1.The front cover of inverter must be closed before inverter is powered on. Otherwise, it may result in an electric shock. 2.The wiring of all peripherals must be conducted in accordance with the guidance of this guide. Otherwise, it may result in an electric hazard. 3

During Operation：

A90 series Inverter User Guide After Power-on ： Danger 1.Do not touch inverter or its peripheral circuits with wet hands to avoid the electric shock. 2.If the indicator is off or the keypad does not display any information after power-on, please cut off the power supply immediately. After 10 minutes of power outages, check wiring for errors. Never touch any terminal of R, S or T of inverter or the connecting terminals with hands or a screw driver, or else an electric shock accident may occur. Contact our customer service personnel immediately after cutting off the power. 3.After power can not touch any terminal of the inverter, must not touch the motor, or there is danger of electric shock.

4.Do not remove any parts of the inverter in the power-on state of the inverter. Caution 1.If the need for parameter identification, please note that the motor rotation of the risk of injury, please confirm the safety and then proceed, otherwise it may cause accidents! 2.Do not arbitrarily change the inverter manufacturers parameters, otherwise it may cause damage to equipment! Maintenance ： Danger 1.Do not live on the equipment for maintenance and repair, or there is danger of electric shock!

2.Cut off the main circuit power supply, confirm the keypad display interface extinguished at least 10 minutes before the implementation of the inverter maintenance and repair, or residual capacitor on the capacitor will cause harm! 3.Without the professional training of personnel Do not carry out the maintenance and maintenance of the inverter, or cause personal injury or equipment damage! 4. After the replacement of the inverter must be set and check the parameters, all pluggable interface must be plugged in the case of power failure! 5.

The power generated when the synchronous machine running.To wait for the motor to stop 10 minutes after power off , then disconnect the motor and inverter connection, and do a good job in order to implement the maintenance and maintenance of the inverter, otherwise there is a Risk of electric shock! During Operation ： Danger 1.Never touch cooling fan, heat sink or discharge resistor with bare hands for checking temperature, which may result in burning! 2.Only qualified technicians are allowed to detect signal during operation so as to prevent personal injury or device damage.

Caution 1.Prevent any foreign items from being dropped into the device during operation, so as to avoid damage to the device. 2.Do not control the start/stop of inverter by ON/OFF of the contactor so as to avoid damage to the device. 4
