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
